It provides multi-head X functionality for displays that might -be located on different machines. -.I Xdmx -functions as a front-end X server that acts as a proxy to a set of -back-end X servers. All of the visible rendering is passed to the -back-end X servers. Clients connect to the -.I Xdmx -front-end, and everything appears as it would in a regular multi-head -configuration. If Xinerama is enabled (e.g., with -.B +xinerama -on the command line), the clients see a single large screen. -.PP -.I Xdmx -communicates to the back-end X servers using the standard X11 protocol, -and standard and/or commonly available X server extensions. -.SH OPTIONS -In addition to the normal X server options described in the -.I Xserver(1) -manual page, -.I Xdmx -accepts the following command line switches: -.TP 8 -.BI "\-display " display-name -This specifies the name(s) of the back-end X server display(s) to connect -to. This option may be specified multiple times to connect to more than -one back-end display. The first is used as screen 0, the second as screen 1, -etc. If this option is omitted, the -.B $DISPLAY -environment variable is used as the single back-end X server display. -.sp -.TP 8 -.BI "\-xinput " input-source -This specifies the source to use for XInput extension devices. The -choices are the same as for -.BR "\-input " , -described below, except that core devices on backend servers cannot be -treated as XInput extension devices. (Although extension devices on -backend and console servers are supported as extension devices under -.IR Xdmx ). -.sp -.TP 8 -.BI "\-input " input-source -This specifies the source to use for the core input devices. The choices are: -.RS -.TP 4 -.B dummy -A set of dummy core input drivers are used. These never generate any -input events. -.sp -.TP 4 -.B local -The raw keyboard and pointer from the local computer are used. A -comma-separated list of driver names can be appended. For example, to -select the example Linux keyboard and PS/2 mouse driver use: -.BR "-input local,kbd,ps2" . -The following drivers have been implemented for Linux: kbd, ms (a -two-button Microsoft mouse driver), ps2 (a PS/2 mouse driver), usb-mou -(a USB mouse driver), usb-kbd (a USB keyboard driver), and usb-oth (a -USB non-keyboard, non-mouse driver). Additional drivers may be -implemented in the future. Appropriate defaults will be used if no -comma-separated list is provided. -.sp -.TP 4 -.I display-name -If the display-name is a back-end server, then core input events are -taken from the server specified. Otherwise, a console window will be -opened on the specified display. -.sp -If the -.I display-name -is followed by ",xi" then XInput extension devices on the display will -be used as -.I Xdmx -XInput extension devices. If the -.I display-name -is followed by ",noxi" then XInput extension devices on the display will -.B not -be used as -.I Xdmx -XInput extension devices. Currently, the default is ",xi". -.sp -If the -.I display-name -is followed by ",console" and the -.I display-name -refers to a display that is used as a backend display, then a console -window will be opened on that display -.B and -that display will be treated as a backend display. Otherwise (or if -",noconsole" is used), the display will be treated purely as a backend -or a console display, as described above. -.sp -If the -.I display-name -is followed by ",windows", then outlines of the windows on the backend -will be displayed inside the console window. Otherwise (or if -",nowindows" is used), the console window will not display the outlines -of backend windows. (This option only applies to console input.) -.sp -If the -.I display-name -is followed by ",xkb", then the next 1 to 3 comma-separated parameters -will specify the keycodes, symbols, and geometry of the keyboard for -this input device. For example, ",xkb,xfree86,pc104" will specify that -the "xfree86" keycodes and the "pc104" symbols should be used to -initialize the keyboard. For an SGI keyboard, ",xkb,sgi/indy(pc102)" -might be useful. A list of keycodes, symbols, and geometries can be -found in -.IR /usr/X11R6/lib/X11/xkb . -If this option is not specified, the input device will be queried, -perhaps using the XKEYBOARD extension. -.RE -.sp -.RS -If this option isn't specified, the default input source is the first -back-end server (the one used for screen 0). The console window shows -the layout of the back-end display(s) and pointer movements and key -presses within the console window will be used as core input devices. -.sp -Several special function keys are active, depending on the input -source: -.sp -.RS -.B Ctrl-Alt-q -will terminate the -.I Xdmx -server in all modes. -.sp -.B Ctrl-Alt-g -will toggle a -server grab in console mode (a special cursor, currently a spider, is -used to indicate an active server grab). -.sp -.B Ctrl-Alt-f -will toggle fine-grain motion in console mode (a special cursor, -currently a cross hair, is used to indicate this mode). If this mode is -combined with a server grab, then the cursor will have 4 lines instead -of only 2. -.sp -.BR Ctrl-Alt-F1 " through " Ctrl-Alt-F12 -will switch to another VC in local (raw) mode. -.RE -.RE -.sp -.TP 8 -.BI "-shadowfb" -This option turns on (legacy) support for the shadow frame buffer. -.sp -.TP 8 -.BI "-noshadowfb" -This option turns off (legacy) support for the shadow frame buffer. -Note that this option has been deprecated and will be removed in the -next release. -.sp -.TP 8 -.BI "-nomulticursor" -This option turns off support for displaying multiple cursors on -overlapped back-end displays. This option is available for testing and -benchmarking purposes. -.sp -.TP 8 -.BI "-fontpath" -This option sets the -.I Xdmx -server's default font path. This option can be specified multiple times -to accommodate multiple font paths. See the -.B "FONT PATHS" -section below for very important information regarding setting the -default font path. -.sp -.TP 8 -.BI "-configfile " filename -Specify the configuration file that should be read. Note that if the -.B \-display -command-line option is used, then the configuration file will be -ignored. -.sp -.TP 8 -.BI "-config " name -Specify a configuration to use. The -.I name -will be the name following the -.B virtual -keyword in the configuration file. -.sp -.TP 8 -.BI "-stat " "interval screens" -This option enables the display of performance statistics. The interval -is in seconds. The screens is a count of the number of back-end screens -for which data is printed each interval. Specifying 0 for screens will -display data for all screens. -.sp -For each screen, the following information is printed: the screen -number, an absolute count of the number of XSync() calls made -(SyncCount), the rate of these calls during the previous interval -(Sync/s), the average round-trip time (in microseconds) of the last 10 -XSync() calls (avSync), the maximum round-trip time (in microseconds) of -the last 10 XSync calls (mxSync), the average number of XSync() requests -that were pending but not yet processed for each of the last 10 -processed XSync() calls, the maximum number of XSync() requests that -were pending but not yet processed for each of the last 10 processed -XSync() calls, and a histogram showing the distribution of the times of -all of the XSync() calls that were made during the previous interval. -.sp -(The length of the moving average and the number and value of histogram -bins are configurable at compile time in the -.B dmxstat.h -header file.) -.sp -.TP 8 -.BI "-syncbatch " interval -This option sets the -.I interval -in milliseconds for XSync() batching. An -.I interval -less than or equal to 0 will disable XSync() batching. The default -.I interval -is 100 ms. -.sp -.TP 8 -.BI "-nooffscreenopt" -This option disables the offscreen optimization. Since the lazy window -creation optimization requires the offscreen optimization to be enabled, -this option will also disable the lazy window creation optimization. -.sp -.TP 8 -.BI "-nowindowopt" -This option disables the lazy window creation optimization. -.sp -.TP 8 -.BI "-nosubdivprims" -This option disables the primitive subdivision optimization. -.sp -.TP 8 -.BI "-noxkb" -Disable use of the XKB extension for communication with the back end -displays. (Combine with -.B "-kb" -to disable all use of XKB.) -.sp -.TP 8 -.BI "-depth " int -This option sets the root window's default depth. When choosing a -default visual from those available on the back-end X server, the first -visual with that matches the depth specified is used. -.sp -This option can be combined with the -.BI "-cc" -option, which specifies the default color visual class, to force the use -of a specific depth and color class for the root window. -.sp -.TP 8 -.BI "-norender" -This option disables the RENDER extension. -.sp -.TP 8 -.BI "-noglxproxy" -This option disables GLX proxy -- the build-in GLX extension -implementation that is DMX aware. -.sp -.TP 8 -.BI "-noglxswapgroup" -This option disables the swap group and swap barrier extensions in GLX -proxy. -.sp -.TP 8 -.BI "-glxsyncswap" -This option enables synchronization after a swap buffers call by waiting -until all X protocol has been processed. When a client issues a -glXSwapBuffers request, Xdmx relays that request to each back-end X -server, and those requests are buffered along with all other protocol -requests. However, in systems that have large network buffers, this -buffering can lead to the set of back-end X servers handling the swap -buffers request asynchronously. With this option, an XSync() request is -issued to each back-end X server after sending the swap buffers request. -The XSync() requests will flush all buffered protocol (including the -swap buffers requests) and wait until the back-end X servers have -processed those requests before continuing. This option does not wait -until all GL commands have been processed so there might be previously -issued commands that are still being processed in the GL pipe when the -XSync() request returns. See the -.BI "-glxfinishswap" -option below if Xdmx should wait until the GL commands have been -processed. -.sp -.TP 8 -.BI "-glxfinishswap" -This option enables synchronization after a swap buffers call by waiting -until all GL commands have been completed.

The second dimension -following -.B wall -is the dimension of each display in the wall (e.g., 1280x1024). -.PP -The first geometry following -.B display -is the geometry of the screen window on the backend server.

This can be most easily handled by -either using a font server (e.g., xfs) or by remotely mounting the font -paths on each back-end server, and then setting the -.I Xdmx -server's default font path with the --I "-fontpath" -command line option described above. -.PP -For example, if you specify a font path with the following command line: -.RS -Xdmx :1 -display d0:0 -fontpath /usr/fonts/75dpi/ -fontpath /usr/fonts/Type1/ +xinerama -.RE -Then, /usr/fonts/75dpi/ and /usr/fonts/Type1/ must be valid font paths -on the -.I Xdmx -server and all back-end server, which is d0 in this example. -.PP -Font servers can also be specified with the -.I "-fontpath" -option. For example, let's assume that a properly configured font -server is running on host d0. Then, the following command line -.RS -Xdmx :1 -display d0:0 -display d1:0 -fontpath tcp/d0:7100 +xinerama -.RE -will initialize the front-end -.I Xdmx -server and each of the back-end servers to use the font server on d0. -.PP -Some fonts might not be supported by either the front-end or the -back-end servers. For example, let's assume the front-end -.I Xdmx -server includes support Type1 fonts, but one of the back-end servers -does not. Let's also assume that the default font path for -.I Xdmx -includes Type1 fonts in its font path. Then, when -.I Xdmx -initializes the default font path to load the default font, the font -path that includes Type1 fonts (along with the other default font paths -that are used by the -.I Xdmx -server) is sent to the back-end server that cannot handle Type1 fonts. -That back-end server then rejects the font path and sends an error back -to the -.I Xdmx -server. -.I Xdmx -then prints an error message and exits because it failed to set the -default font path and was unable load the default font. -.PP -To fix this error, the offending font path must be removed from the -default font path by using a different -.I "-fontpath" -command line option. -.PP -The -.I "-fontpath" -option can also be added to the configuration file as described above. -.SH "COMMAND-LINE EXAMPLES" -The back-end machines are d0 and d1, core input is from the pointer and -keyboard attached to d0, clients will refer to :1 when opening windows: -.RS -Xdmx :1 -display d0:0 -display d1:0 +xinerama -.RE -.PP -As above, except with core input from d1: -.RS -Xdmx :1 -display d0:0 -display d1:0 -input d1:0 +xinerama -.RE -.PP -As above, except with core input from a console window on the local -display: -.RS -Xdmx :1 -display d0:0 -display d1:0 -input :0 +xinerama -.RE -.PP -As above, except with core input from the local keyboard and mouse: -.RS -Xdmx :1 -display d0:0 -display d1:0 -input local,kbd,ps2 +xinerama -.RE -Note that local input can be used under Linux while another X session is -running on :0 (assuming the user can access the Linux console tty and -mouse devices): a new (blank) VC will be used for keyboard input on the -local machine and the Ctrl-Alt-F* sequence will be available to change -to another VC (possibly back to another X session running on the local -machine). Using Ctrl-Alt-Backspace on the blank VC will terminate the -Xdmx session and return to the original VC. -.PP -This example uses the configuration file shown in the previous section: -.RS -Xdmx :1 -input :0 +xinerama -configfile filename -config example2 -.RE -With this configuration file line: -.RS -option -input :0 +xinerama; -.RE -the command line can be shortened to: -.RS -Xdmx :1 -configfile filename -config example2 -.RE -.SH "USING THE USB DEVICE DRIVERS" -.P -The USB device drivers use the devices called -.IR /dev/input/event0 ", " /dev/input/event1 ", etc." -under Linux. These devices are driven using the -.I evdev -Linux kernel module, which is part of the hid suite. Please note that -if you load the -.I mousedev -or -.I kbddev -Linux kernel modules, then USB devices will appear as core Linux input -devices and you will not be able to select between using the device only -as an -.I Xdmx -core device or an -.I Xdmx -XInput extension device. Further, you may be unable to unload the -.I mousedev -Linux kernel module if -.I XFree86 -is configured to use -.I /dev/input/mice -as an input device (this is quite helpful for laptop users and is set up -by default under some Linux distributions, but should be changed if USB -devices are to be used with -.IR Xdmx ). -.PP -The USB device drivers search through the Linux devices for the first -mouse, keyboard, or non-mouse-non-keyboard Linux device and use that -device. -.SH "KEYBOARD INITIALIZATION" -.PP -If -.I Xdmx -was invoked with -.I \-xkb -or was -.B not -compiled to use the XKEYBOARD extension, then a keyboard on a backend or -console will be initialized using the map that the host X server -provides. -.PP -If the XKEYBOARD extension is used for both -.I Xdmx -and the host X server for the keyboard (i.e., the backend or console X -server), then the type of the keyboard will -be obtained from the host X server and the keyboard under -.I Xdmx -will be initialized with that information. Otherwise, the default type -of keyboard will be initialized. In both cases, the map from the host X -server will -.B not -be used. This means that different initial behavior may be noted with -and without XKEYBOARD. Consistent and expected results will be obtained -by running XKEYBOARD on all servers and by avoiding the use of -.I xmodmap -on the backend or console X servers prior to starting -.IR Xdmx . -.PP -If -.I \-xkbmap -is specified on the -.I Xdmx -command line, then that map will currently be used for all keyboards. -.SH "MULTIPLE CORE KEYBOARDS" -X was not designed to support multiple core keyboards. However, -.I Xdmx -provides some support for multiple core keyboards. Best results will be -obtained if all of the keyboards are of the same type and are using the -same keyboard map. Because the X server passes raw key code information -to the X client, key symbols for keyboards with different key maps would -be different if the key code for each keyboard was sent without -translation to the client. Therefore, -.I Xdmx -will attempt to translate the key code from a core keyboard to the key -code for the key with the same key symbol of the -.B first -core keyboard that was loaded. If the key symbol appears in both maps, -the results will be expected. Otherwise, the second core keyboard will -return a NoSymbol key symbol for some keys that would have been -translated if it was the first core keyboard. -.ig -.SH ENVIRONMENT -.. -.ig -.SH FILES -.. -.SH "SEE ALSO" -.BR DMX "(3X), " X "(__miscmansuffix__), " Xserver "(1), " xdmxconfig "(1), " -.BR vdltodmx "(1), " xfs "(1), " xkbcomp (1) -.SH AUTHORS -Kevin E.

It provides multi-head X functionality for displays that might +be located on different machines. +.I Xdmx +functions as a front-end X server that acts as a proxy to a set of +back-end X servers. All of the visible rendering is passed to the +back-end X servers. Clients connect to the +.I Xdmx +front-end, and everything appears as it would in a regular multi-head +configuration. If Xinerama is enabled (e.g., with +.B +xinerama +on the command line), the clients see a single large screen. +.PP +.I Xdmx +communicates to the back-end X servers using the standard X11 protocol, +and standard and/or commonly available X server extensions. +.SH OPTIONS +In addition to the normal X server options described in the +.I Xserver(1) +manual page, +.I Xdmx +accepts the following command line switches: +.TP 8 +.BI "\-display " display-name +This specifies the name(s) of the back-end X server display(s) to connect +to. This option may be specified multiple times to connect to more than +one back-end display. The first is used as screen 0, the second as screen 1, +etc. If this option is omitted, the +.B $DISPLAY +environment variable is used as the single back-end X server display. +.sp +.TP 8 +.BI "\-xinput " input-source +This specifies the source to use for XInput extension devices. The +choices are the same as for +.BR "\-input " , +described below, except that core devices on backend servers cannot be +treated as XInput extension devices. (Although extension devices on +backend and console servers are supported as extension devices under +.IR Xdmx ). +.sp +.TP 8 +.BI "\-input " input-source +This specifies the source to use for the core input devices. The choices are: +.RS +.TP 4 +.B dummy +A set of dummy core input drivers are used. These never generate any +input events. +.sp +.TP 4 +.B local +The raw keyboard and pointer from the local computer are used. A +comma-separated list of driver names can be appended. For example, to +select the example Linux keyboard and PS/2 mouse driver use: +.BR "-input local,kbd,ps2" . +The following drivers have been implemented for Linux: kbd, ms (a +two-button Microsoft mouse driver), ps2 (a PS/2 mouse driver), usb-mou +(a USB mouse driver), usb-kbd (a USB keyboard driver), and usb-oth (a +USB non-keyboard, non-mouse driver). Additional drivers may be +implemented in the future. Appropriate defaults will be used if no +comma-separated list is provided. +.sp +.TP 4 +.I display-name +If the display-name is a back-end server, then core input events are +taken from the server specified. Otherwise, a console window will be +opened on the specified display. +.sp +If the +.I display-name +is followed by ",xi" then XInput extension devices on the display will +be used as +.I Xdmx +XInput extension devices. If the +.I display-name +is followed by ",noxi" then XInput extension devices on the display will +.B not +be used as +.I Xdmx +XInput extension devices. Currently, the default is ",xi". +.sp +If the +.I display-name +is followed by ",console" and the +.I display-name +refers to a display that is used as a backend display, then a console +window will be opened on that display +.B and +that display will be treated as a backend display. Otherwise (or if +",noconsole" is used), the display will be treated purely as a backend +or a console display, as described above. +.sp +If the +.I display-name +is followed by ",windows", then outlines of the windows on the backend +will be displayed inside the console window. Otherwise (or if +",nowindows" is used), the console window will not display the outlines +of backend windows. (This option only applies to console input.) +.sp +If the +.I display-name +is followed by ",xkb", then the next 1 to 3 comma-separated parameters +will specify the keycodes, symbols, and geometry of the keyboard for +this input device. For example, ",xkb,xfree86,pc104" will specify that +the "xfree86" keycodes and the "pc104" symbols should be used to +initialize the keyboard. For an SGI keyboard, ",xkb,sgi/indy(pc102)" +might be useful. A list of keycodes, symbols, and geometries can be +found in +.IR /usr/X11R6/lib/X11/xkb . +If this option is not specified, the input device will be queried, +perhaps using the XKEYBOARD extension. +.RE +.sp +.RS +If this option isn't specified, the default input source is the first +back-end server (the one used for screen 0). The console window shows +the layout of the back-end display(s) and pointer movements and key +presses within the console window will be used as core input devices. +.sp +Several special function keys are active, depending on the input +source: +.sp +.RS +.B Ctrl-Alt-q +will terminate the +.I Xdmx +server in all modes. +.sp +.B Ctrl-Alt-g +will toggle a +server grab in console mode (a special cursor, currently a spider, is +used to indicate an active server grab). +.sp +.B Ctrl-Alt-f +will toggle fine-grain motion in console mode (a special cursor, +currently a cross hair, is used to indicate this mode). If this mode is +combined with a server grab, then the cursor will have 4 lines instead +of only 2. +.sp +.BR Ctrl-Alt-F1 " through " Ctrl-Alt-F12 +will switch to another VC in local (raw) mode. +.RE +.RE +.sp +.TP 8 +.BI "-shadowfb" +This option turns on (legacy) support for the shadow frame buffer. +.sp +.TP 8 +.BI "-noshadowfb" +This option turns off (legacy) support for the shadow frame buffer. +Note that this option has been deprecated and will be removed in the +next release. +.sp +.TP 8 +.BI "-nomulticursor" +This option turns off support for displaying multiple cursors on +overlapped back-end displays. This option is available for testing and +benchmarking purposes. +.sp +.TP 8 +.BI "-fontpath" +This option sets the +.I Xdmx +server's default font path. This option can be specified multiple times +to accommodate multiple font paths. See the +.B "FONT PATHS" +section below for very important information regarding setting the +default font path. +.sp +.TP 8 +.BI "-configfile " filename +Specify the configuration file that should be read. Note that if the +.B \-display +command-line option is used, then the configuration file will be +ignored. +.sp +.TP 8 +.BI "-config " name +Specify a configuration to use. The +.I name +will be the name following the +.B virtual +keyword in the configuration file. +.sp +.TP 8 +.BI "-stat " "interval screens" +This option enables the display of performance statistics. The interval +is in seconds. The screens is a count of the number of back-end screens +for which data is printed each interval. Specifying 0 for screens will +display data for all screens. +.sp +For each screen, the following information is printed: the screen +number, an absolute count of the number of XSync() calls made +(SyncCount), the rate of these calls during the previous interval +(Sync/s), the average round-trip time (in microseconds) of the last 10 +XSync() calls (avSync), the maximum round-trip time (in microseconds) of +the last 10 XSync calls (mxSync), the average number of XSync() requests +that were pending but not yet processed for each of the last 10 +processed XSync() calls, the maximum number of XSync() requests that +were pending but not yet processed for each of the last 10 processed +XSync() calls, and a histogram showing the distribution of the times of +all of the XSync() calls that were made during the previous interval. +.sp +(The length of the moving average and the number and value of histogram +bins are configurable at compile time in the +.B dmxstat.h +header file.) +.sp +.TP 8 +.BI "-syncbatch " interval +This option sets the +.I interval +in milliseconds for XSync() batching. An +.I interval +less than or equal to 0 will disable XSync() batching. The default +.I interval +is 100 ms. +.sp +.TP 8 +.BI "-nooffscreenopt" +This option disables the offscreen optimization. Since the lazy window +creation optimization requires the offscreen optimization to be enabled, +this option will also disable the lazy window creation optimization. +.sp +.TP 8 +.BI "-nowindowopt" +This option disables the lazy window creation optimization. +.sp +.TP 8 +.BI "-nosubdivprims" +This option disables the primitive subdivision optimization. +.sp +.TP 8 +.BI "-noxkb" +Disable use of the XKB extension for communication with the back end +displays. (Combine with +.B "-kb" +to disable all use of XKB.) +.sp +.TP 8 +.BI "-depth " int +This option sets the root window's default depth. When choosing a +default visual from those available on the back-end X server, the first +visual with that matches the depth specified is used. +.sp +This option can be combined with the +.BI "-cc" +option, which specifies the default color visual class, to force the use +of a specific depth and color class for the root window. +.sp +.TP 8 +.BI "-norender" +This option disables the RENDER extension. +.sp +.TP 8 +.BI "-noglxproxy" +This option disables GLX proxy -- the build-in GLX extension +implementation that is DMX aware. +.sp +.TP 8 +.BI "-noglxswapgroup" +This option disables the swap group and swap barrier extensions in GLX +proxy. +.sp +.TP 8 +.BI "-glxsyncswap" +This option enables synchronization after a swap buffers call by waiting +until all X protocol has been processed. When a client issues a +glXSwapBuffers request, Xdmx relays that request to each back-end X +server, and those requests are buffered along with all other protocol +requests. However, in systems that have large network buffers, this +buffering can lead to the set of back-end X servers handling the swap +buffers request asynchronously. With this option, an XSync() request is +issued to each back-end X server after sending the swap buffers request. +The XSync() requests will flush all buffered protocol (including the +swap buffers requests) and wait until the back-end X servers have +processed those requests before continuing. This option does not wait +until all GL commands have been processed so there might be previously +issued commands that are still being processed in the GL pipe when the +XSync() request returns. See the +.BI "-glxfinishswap" +option below if Xdmx should wait until the GL commands have been +processed. +.sp +.TP 8 +.BI "-glxfinishswap" +This option enables synchronization after a swap buffers call by waiting +until all GL commands have been completed. It is similar to the +.BI "-glxsyncswap" +option above; however, instead of issuing an XSync(), it issues a +glFinish() request to each back-end X server after sending the swap +buffers requests. The glFinish() request will flush all buffered +protocol requests, process both X and GL requests, and wait until all +previously called GL commands are complete before returning. +.sp +.TP 8 +.BI "-ignorebadfontpaths" +This option ignores font paths that are not available on all back-end +servers by removing the bad font path(s) from the default font path +list. If no valid font paths are left after removing the bad paths, an +error to that effect is printed in the log. +.sp +.TP 8 +.BI "-addremovescreens" +This option enables the dynamic addition and removal of screens, which +is disabled by default. Note that GLXProxy and Render do not yet +support dynamic addition and removal of screens, and must be disabled +via the +.BI "-noglxproxy" +and +.BI "-norender" +command line options described above. +.sp +.TP 8 +.BI "-param" +This option specifies parameters on the command line. Currently, only +parameters dealing with XKEYBOARD configuration are supported. These +parameters apply only to the core keyboard. Parameter values are +installation-dependent. Please see +.I /usr/X11R6/lib/X11/xkb +or a similar directory for complete information. +.RS +.TP 8 +.B XkbRules +Defaults to "xfree86".

This can be most easily handled by +either using a font server (e.g., xfs) or by remotely mounting the font +paths on each back-end server, and then setting the +.I Xdmx +server's default font path with the +-I "-fontpath" +command line option described above. +.PP +For example, if you specify a font path with the following command line: +.RS +Xdmx :1 -display d0:0 -fontpath /usr/fonts/75dpi/ -fontpath /usr/fonts/Type1/ +xinerama +.RE +Then, /usr/fonts/75dpi/ and /usr/fonts/Type1/ must be valid font paths +on the +.I Xdmx +server and all back-end server, which is d0 in this example. +.PP +Font servers can also be specified with the +.I "-fontpath" +option. For example, let's assume that a properly configured font +server is running on host d0. Then, the following command line +.RS +Xdmx :1 -display d0:0 -display d1:0 -fontpath tcp/d0:7100 +xinerama +.RE +will initialize the front-end +.I Xdmx +server and each of the back-end servers to use the font server on d0. +.PP +Some fonts might not be supported by either the front-end or the +back-end servers. For example, let's assume the front-end +.I Xdmx +server includes support Type1 fonts, but one of the back-end servers +does not. Let's also assume that the default font path for +.I Xdmx +includes Type1 fonts in its font path. Then, when +.I Xdmx +initializes the default font path to load the default font, the font +path that includes Type1 fonts (along with the other default font paths +that are used by the +.I Xdmx +server) is sent to the back-end server that cannot handle Type1 fonts. +That back-end server then rejects the font path and sends an error back +to the +.I Xdmx +server. +.I Xdmx +then prints an error message and exits because it failed to set the +default font path and was unable load the default font. +.PP +To fix this error, the offending font path must be removed from the +default font path by using a different +.I "-fontpath" +command line option. +.PP +The +.I "-fontpath" +option can also be added to the configuration file as described above. +.SH "COMMAND-LINE EXAMPLES" +The back-end machines are d0 and d1, core input is from the pointer and +keyboard attached to d0, clients will refer to :1 when opening windows: +.RS +Xdmx :1 -display d0:0 -display d1:0 +xinerama +.RE +.PP +As above, except with core input from d1: +.RS +Xdmx :1 -display d0:0 -display d1:0 -input d1:0 +xinerama +.RE +.PP +As above, except with core input from a console window on the local +display: +.RS +Xdmx :1 -display d0:0 -display d1:0 -input :0 +xinerama +.RE +.PP +As above, except with core input from the local keyboard and mouse: +.RS +Xdmx :1 -display d0:0 -display d1:0 -input local,kbd,ps2 +xinerama +.RE +Note that local input can be used under Linux while another X session is +running on :0 (assuming the user can access the Linux console tty and +mouse devices): a new (blank) VC will be used for keyboard input on the +local machine and the Ctrl-Alt-F* sequence will be available to change +to another VC (possibly back to another X session running on the local +machine).

These devices are driven using the +.I evdev +Linux kernel module, which is part of the hid suite. Please note that +if you load the +.I mousedev +or +.I kbddev +Linux kernel modules, then USB devices will appear as core Linux input +devices and you will not be able to select between using the device only +as an +.I Xdmx +core device or an +.I Xdmx +XInput extension device. Further, you may be unable to unload the +.I mousedev +Linux kernel module if +.I XFree86 +is configured to use +.I /dev/input/mice +as an input device (this is quite helpful for laptop users and is set up +by default under some Linux distributions, but should be changed if USB +devices are to be used with +.IR Xdmx ). +.PP +The USB device drivers search through the Linux devices for the first +mouse, keyboard, or non-mouse-non-keyboard Linux device and use that +device. +.SH "KEYBOARD INITIALIZATION" +.PP +If +.I Xdmx +was invoked with +.I \-xkb +or was +.B not +compiled to use the XKEYBOARD extension, then a keyboard on a backend or +console will be initialized using the map that the host X server +provides. +.PP +If the XKEYBOARD extension is used for both +.I Xdmx +and the host X server for the keyboard (i.e., the backend or console X +server), then the type of the keyboard will +be obtained from the host X server and the keyboard under +.I Xdmx +will be initialized with that information. Otherwise, the default type +of keyboard will be initialized. In both cases, the map from the host X +server will +.B not +be used. This means that different initial behavior may be noted with +and without XKEYBOARD. Consistent and expected results will be obtained +by running XKEYBOARD on all servers and by avoiding the use of +.I xmodmap +on the backend or console X servers prior to starting +.IR Xdmx . +.PP +If +.I \-xkbmap +is specified on the +.I Xdmx +command line, then that map will currently be used for all keyboards. +.SH "MULTIPLE CORE KEYBOARDS" +X was not designed to support multiple core keyboards. However, +.I Xdmx +provides some support for multiple core keyboards. Best results will be +obtained if all of the keyboards are of the same type and are using the +same keyboard map. Because the X server passes raw key code information +to the X client, key symbols for keyboards with different key maps would +be different if the key code for each keyboard was sent without +translation to the client. Therefore, +.I Xdmx +will attempt to translate the key code from a core keyboard to the key +code for the key with the same key symbol of the +.B first +core keyboard that was loaded. If the key symbol appears in both maps, +the results will be expected. Otherwise, the second core keyboard will +return a NoSymbol key symbol for some keys that would have been +translated if it was the first core keyboard. +.ig +.SH ENVIRONMENT +.. +.ig +.SH FILES +.. +.SH "SEE ALSO" +.BR DMX "(3X), " X "(__miscmansuffix__), " Xserver "(1), " xdmxconfig "(1), " +.BR vdltodmx "(1), " xfs "(1), " xkbcomp (1) +.SH AUTHORS +Kevin E.

It now runs +on a wider range of hardware and OS platforms. +.PP +This work was derived by the X.Org Foundation from the XFree86 Project's +.I "XFree86\ 4.4rc2" +release. +The XFree86 release was originally derived from +.I "X386\ 1.2" +by Thomas Roell which was contributed to X11R5 by Snitily Graphics +Consulting Service. +.SH PLATFORMS +.PP +.B __xservername__ +operates under a wide range of operating systems and hardware platforms. +The Intel x86 (IA32) architecture is the most widely supported hardware +platform. Other hardware platforms include Compaq Alpha, Intel IA64, AMD64, +SPARC and PowerPC. The most widely supported operating systems are the +free/OpenSource UNIX-like systems such as Linux, FreeBSD, NetBSD, +OpenBSD, and Solaris. Commercial UNIX operating systems such as +UnixWare are also supported. Other supported operating systems include +GNU Hurd. Mac OS X is supported with the +Xquartz(__appmansuffix__) X server. Win32/Cygwin is supported with the +XWin(__appmansuffix__) X server. +.PP +.SH "NETWORK CONNECTIONS" +.B __xservername__ +supports connections made using the following reliable +byte-streams: +.TP 4 +.I "Local" +On most platforms, the "Local" connection type is a UNIX-domain socket. +On some System V platforms, the "local" connection types also include +STREAMS pipes, named pipes, and some other mechanisms. +.TP 4 +.I TCP\/IP +.B __xservername__ +listens on port +.RI 6000+ n , +where +.I n +is the display number. This connection type can be disabled with the +.B \-nolisten +option (see the Xserver(1) man page for details). +.SH "ENVIRONMENT VARIABLES" +For operating systems that support local connections other than Unix +Domain sockets (SVR3 and SVR4), there is a compiled-in list specifying +the order in which local connections should be attempted. This list +can be overridden by the +.I XLOCAL +environment variable described below. If the display name indicates a +best-choice connection should be made (e.g. +.BR :0.0 ), +each connection mechanism is tried until a connection succeeds or no +more mechanisms are available. Note: for these OSs, the Unix Domain +socket connection is treated differently from the other local connection +types. To use it the connection must be made to +.BR unix:0.0 . +.PP +The +.I XLOCAL +environment variable should contain a list of one more +more of the following: +.PP +.RS 8 +.nf +NAMED +PTS +SCO +ISC +.fi +.RE +.PP +which represent SVR4 Named Streams pipe, Old-style USL Streams pipe, +SCO XSight Streams pipe, and ISC Streams pipe, respectively. You can +select a single mechanism (e.g. +.IR XLOCAL=NAMED ), +or an ordered list (e.g. \fIXLOCAL="NAMED:PTS:SCO"\fP). +his variable overrides the compiled-in defaults. For SVR4 it is +recommended that +.I NAMED +be the first preference connection. The default setting is +.IR PTS:NAMED:ISC:SCO . +.PP +To globally override the compiled-in defaults, you should define (and +export if using +.B sh +or +.BR ksh ) +.I XLOCAL +globally. If you use startx(1) or xinit(1), the definition should be +at the top of your +.I .xinitrc +file. If you use xdm(1), the definitions should be early on in the +.I __projectroot__/lib/X11/xdm/Xsession +script. +.SH OPTIONS +.B __xservername__ +supports several mechanisms for supplying/obtaining configuration and +run-time parameters: command line options, environment variables, the +__xconfigfile__(__filemansuffix__) configuration files, auto-detection, and +fallback defaults. When the same information is supplied in more than +one way, the highest precedence mechanism is used. The list of mechanisms +is ordered from highest precedence to lowest. Note that not all parameters +can be supplied via all methods. The available command line options +and environment variables (and some defaults) are described here and in +the Xserver(__appmansuffix__) manual page. Most configuration file +parameters, with their defaults, are described in the +__xconfigfile__(__filemansuffix__) manual page. Driver and module specific +configuration parameters are described in the relevant driver or module +manual page. +.PP +In addition to the normal server options described in the +Xserver(__appmansuffix__) manual page, +.B __xservername__ +accepts the following command line switches: +.TP 8 +.BI vt XX +.I XX +specifies the Virtual Terminal device number which +.B __xservername__ +will use. Without this option, +.B __xservername__ +will pick the first available Virtual Terminal that it can locate. This +option applies only to platforms that have virtual terminal support, such +as Linux, BSD, OpenSolaris, SVR3, and SVR4. +.TP +.B \-allowMouseOpenFail +Allow the server to start up even if the mouse device can't be opened +or initialised. This is equivalent to the +.B AllowMouseOpenFail +__xconfigfile__(__filemansuffix__) file option. +.TP 8 +.B \-allowNonLocalXvidtune +Make the VidMode extension available to remote clients. This allows +the xvidtune client to connect from another host. This is equivalent +to the +.B AllowNonLocalXvidtune +__xconfigfile__(__filemansuffix__) file option. By default non-local +connections are not allowed. +.TP 8 +.BI \-bgamma " value" +Set the blue gamma correction. +.I value +must be between 0.1 and 10. +The default is 1.0. Not all drivers support this. See also the +.BR \-gamma , +.BR \-rgamma , +and +.B \-ggamma +options. +.TP 8 +.BI \-bpp " n" +No longer supported. Use +.B \-depth +to set the color depth, and use +.B \-fbbpp +if you really need to force a non-default framebuffer (hardware) pixel +format. +.TP 8 +.BI \-config " file" +Read the server configuration from +.IR file . +This option will work for any file when the server is run as root (i.e, +with real-uid 0), or for files relative to a directory in the config +search path for all other users. +.TP 8 +.BI \-configdir " directory" +Read the server configuration files from +.IR directory . +This option will work for any directory when the server is run as root +(i.e, with real-uid 0), or for directories relative to a directory in the +config directory search path for all other users. +.TP 8 +.B \-configure +When this option is specified, the +.B __xservername__ +server loads all video driver modules, probes for available hardware, +and writes out an initial __xconfigfile__(__filemansuffix__) file based on +what was detected. This option currently has some problems on some +platforms, but in most cases it is a good way to bootstrap the +configuration process. This option is only available when the server +is run as root (i.e, with real-uid 0). +.TP 8 +.BI "\-crt /dev/tty" XX +SCO only. This is the same as the +.B vt +option, and is provided for compatibility with the native SCO X server. +.TP 8 +.BI \-depth " n" +Sets the default color depth. Legal values are 1, 4, 8, 15, 16, and +24. Not all drivers support all values. +.TP 8 +.B \-disableVidMode +Disable the parts of the VidMode extension (used by the xvidtune +client) that can be used to change the video modes. This is equivalent +to the +.B DisableVidModeExtension +__xconfigfile__(__filemansuffix__) file option. +.TP 8 +.B \-fbbpp \fIn\fP +Sets the number of framebuffer bits per pixel. You should only set this +if you're sure it's necessary; normally the server can deduce the correct +value from +.B \-depth +above. Useful if you want to run a depth 24 configuration with a 24 +bpp framebuffer rather than the (possibly default) 32 bpp framebuffer +(or vice versa). Legal values are 1, 8, 16, 24, 32. Not all drivers +support all values. +.TP 8 +.B \-flipPixels +Swap the default values for the black and white pixels. +.TP 8 +.BI \-gamma " value" +Set the gamma correction. +.I value +must be between 0.1 and 10. The default is 1.0. This value is applied +equally to the R, G and B values. Those values can be set independently +with the +.BR \-rgamma , +.BR \-bgamma , +and +.B \-ggamma +options. Not all drivers support this. +.TP 8 +.BI \-ggamma " value" +Set the green gamma correction. +.I value +must be between 0.1 and 10. The default is 1.0. Not all drivers support +this. See also the +.BR \-gamma , +.BR \-rgamma , +and +.B \-bgamma +options. +.TP 8 +.B \-ignoreABI +The +.B __xservername__ +server checks the ABI revision levels of each module that it loads. It +will normally refuse to load modules with ABI revisions that are newer +than the server's. This is because such modules might use interfaces +that the server does not have. When this option is specified, mismatches +like this are downgraded from fatal errors to warnings. This option +should be used with care. +.TP 8 +.B \-isolateDevice \fIbus\-id\fP +Restrict device resets to the device at +.IR bus\-id . +The +.I bus\-id +string has the form +.IB bustype : bus : device : function +(e.g., \(oqPCI:1:0:0\(cq). +At present, only isolation of PCI devices is supported; i.e., this option +is ignored if +.I bustype +is anything other than \(oqPCI\(cq. +.TP 8 +.B \-keeptty +Prevent the server from detaching its initial controlling terminal. +This option is only useful when debugging the server. Not all platforms +support (or can use) this option. +.TP 8 +.BI \-keyboard " keyboard-name" +Use the __xconfigfile__(__filemansuffix__) file +.B InputDevice +section called +.I keyboard-name +as the core keyboard. This option is ignored when the +.B Layout +section specifies a core keyboard. In the absence of both a Layout +section and this option, the first relevant +.B InputDevice +section is used for the core keyboard. +.TP 8 +.BI \-layout " layout-name" +Use the __xconfigfile__(__filemansuffix__) file +.B Layout +section called +.IR layout-name . +By default the first +.B Layout +section is used. +.TP 8 +.BI \-logfile " filename" +Use the file called +.I filename +as the +.B __xservername__ +server log file. The default log file is +.BI __logdir__/__xservername__. n .log +on most platforms, where +.I n +is the display number of the +.B __xservername__ +server. The default may be in a different directory on some platforms. +This option is only available when the server is run as root (i.e, with +real-uid 0). +.TP 8 +.BR \-logverbose " [\fIn\fP]" +Sets the verbosity level for information printed to the +.B __xservername__ +server log file. If the +.I n +value isn't supplied, each occurrence of this option increments the log +file verbosity level. When the +.I n +value is supplied, the log file verbosity level is set to that value. +The default log file verbosity level is 3. +.TP 8 +.BI \-modulepath " searchpath" +Set the module search path to +.IR searchpath . +.I searchpath +is a comma separated list of directories to search for +.B __xservername__ +server modules. This option is only available when the server is run +as root (i.e, with real-uid 0). +.TP 8 +.B \-nosilk +Disable Silken Mouse support. +.TP 8 +.B \-pixmap24 +Set the internal pixmap format for depth 24 pixmaps to 24 bits per pixel. +The default is usually 32 bits per pixel. There is normally little +reason to use this option. Some client applications don't like this +pixmap format, even though it is a perfectly legal format. This is +equivalent to the +.B Pixmap +__xconfigfile__(__filemansuffix__) file option. +.TP 8 +.B \-pixmap32 +Set the internal pixmap format for depth 24 pixmaps to 32 bits per pixel. +This is usually the default. This is equivalent to the +.B Pixmap +__xconfigfile__(__filemansuffix__) file option. +.TP 8 +.BI \-pointer " pointer-name" +Use the __xconfigfile__(__filemansuffix__) file +.B InputDevice +section called +.I pointer-name +as the core pointer. This option is ignored when the +.B Layout +section specifies a core pointer. In the absence of both a Layout +section and this option, the first relevant +.B InputDevice +section is used for the core pointer. +.TP 8 +.B \-quiet +Suppress most informational messages at startup. The verbosity level +is set to zero. +.TP 8 +.BI \-rgamma " value" +Set the red gamma correction. +.I value +must be between 0.1 and 10. The default is 1.0. Not all drivers support +this. See also the +.BR \-gamma , +.BR \-bgamma , +and +.B \-ggamma +options. +.TP 8 +.BI \-screen " screen-name" +Use the __xconfigfile__(__filemansuffix__) file +.B Screen +section called +.IR screen-name . +By default the screens referenced by the default +.B Layout +section are used, or the first +.B Screen +section when there are no +.B Layout +sections. +.TP 8 +.B \-showconfig +This is the same as the +.B \-version +option, and is included for compatibility reasons. It may be removed +in a future release, so the +.B \-version +option should be used instead. +.TP 8 +.B \-showDefaultModulePath +Print out the default module path the server was compiled with. +.TP 8 +.B \-showDefaultLibPath +Print out the path libraries should be installed to. +.TP 8 +.B \-showopts +For each driver module installed, print out the list of options and their +argument types. +.TP 8 +.BI \-weight " nnn" +Set RGB weighting at 16 bpp. The default is 565. This applies only to +those drivers which support 16 bpp. +.TP 8 +.BR \-verbose " [\fIn\fP]" +Sets the verbosity level for information printed on stderr. If the +.I n +value isn't supplied, each occurrence of this option increments the +verbosity level. When the +.I n +value is supplied, the verbosity level is set to that value. The default +verbosity level is 0. +.TP 8 +.B \-version +Print out the server version, patchlevel, release date, the operating +system/platform it was built on, and whether it includes module loader +support. +.SH "KEYBOARD" +.PP +The +.B __xservername__ +server is normally configured to recognize various special combinations +of key presses that instruct the server to perform some action, rather +than just sending the key press event to a client application. These actions +depend on the XKB keymap loaded by a particular keyboard device and may or +may not be available on a given configuration. +.PP +The following key combinations are commonly part of the default XKEYBOARD +keymap. +.TP 8 +.B Ctrl+Alt+Backspace +Immediately kills the server -- no questions asked. It can be disabled by +setting the +.B DontZap +__xconfigfile__(__filemansuffix__) file option to a TRUE value. +.PP +.RS 8 +It should be noted that zapping is triggered by the +.B Terminate_Server +action in the keyboard map. This action is not part of the default keymaps +but can be enabled with the XKB option +.B \*qterminate:ctrl_alt_bksp\*q. +.RE +.TP 8 +.B Ctrl+Alt+Keypad-Plus +Change video mode to next one specified in the configuration file. +This can be disabled with the +.B DontZoom +__xconfigfile__(__filemansuffix__) file option. +.TP 8 +.B Ctrl+Alt+Keypad-Minus +Change video mode to previous one specified in the configuration file. +This can be disabled with the +.B DontZoom +__xconfigfile__(__filemansuffix__) file option. +.TP 8 +.B Ctrl+Alt+F1...F12 +For systems with virtual terminal support, these keystroke +combinations are used to switch to virtual terminals 1 through 12, +respectively. This can be disabled with the +.B DontVTSwitch +__xconfigfile__(__filemansuffix__) file option. +.SH CONFIGURATION +.B __xservername__ +typically uses a configuration file called +.B __xconfigfile__ +and configuration files with the suffix +.I .conf +in a directory called +.B __xconfigdir__ +for its initial setup. +Refer to the __xconfigfile__(__filemansuffix__) manual page for information +about the format of this file. +.PP +.B __xservername__ +has a mechanism for automatically generating a built-in configuration +at run-time when no +.B __xconfigfile__ +file or +.B __xconfigdir__ +files are present. The current version of this automatic configuration +mechanism works in two ways. +.PP +The first is via enhancements that have made many components of the +.B __xconfigfile__ +file optional. This means that information that can be probed or +reasonably deduced doesn't need to be specified explicitly, greatly +reducing the amount of built-in configuration information that needs to +be generated at run-time. +.PP +The second is to have "safe" fallbacks for most configuration information. +This maximises the likelihood that the +.B __xservername__ +server will start up in some usable configuration even when information +about the specific hardware is not available. +.PP +The automatic configuration support for __xservername__ is work in progress. +It is currently aimed at the most popular hardware and software platforms +supported by __xservername__.

It now runs -on a wider range of hardware and OS platforms. -.PP -This work was derived by the X.Org Foundation from the XFree86 Project's -.I "XFree86\ 4.4rc2" -release. -The XFree86 release was originally derived from -.I "X386\ 1.2" -by Thomas Roell which was contributed to X11R5 by Snitily Graphics -Consulting Service. -.SH PLATFORMS -.PP -.B __xservername__ -operates under a wide range of operating systems and hardware platforms. -The Intel x86 (IA32) architecture is the most widely supported hardware -platform. Other hardware platforms include Compaq Alpha, Intel IA64, AMD64, -SPARC and PowerPC. The most widely supported operating systems are the -free/OpenSource UNIX-like systems such as Linux, FreeBSD, NetBSD, -OpenBSD, and Solaris. Commercial UNIX operating systems such as -UnixWare are also supported. Other supported operating systems include -GNU Hurd. Mac OS X is supported with the -Xquartz(__appmansuffix__) X server. Win32/Cygwin is supported with the -XWin(__appmansuffix__) X server. -.PP -.SH "NETWORK CONNECTIONS" -.B __xservername__ -supports connections made using the following reliable -byte-streams: -.TP 4 -.I "Local" -On most platforms, the "Local" connection type is a UNIX-domain socket. -On some System V platforms, the "local" connection types also include -STREAMS pipes, named pipes, and some other mechanisms. -.TP 4 -.I TCP\/IP -.B __xservername__ -listens on port -.RI 6000+ n , -where -.I n -is the display number. This connection type can be disabled with the -.B \-nolisten -option (see the Xserver(1) man page for details). -.SH "ENVIRONMENT VARIABLES" -For operating systems that support local connections other than Unix -Domain sockets (SVR3 and SVR4), there is a compiled-in list specifying -the order in which local connections should be attempted. This list -can be overridden by the -.I XLOCAL -environment variable described below. If the display name indicates a -best-choice connection should be made (e.g. -.BR :0.0 ), -each connection mechanism is tried until a connection succeeds or no -more mechanisms are available. Note: for these OSs, the Unix Domain -socket connection is treated differently from the other local connection -types. To use it the connection must be made to -.BR unix:0.0 . -.PP -The -.I XLOCAL -environment variable should contain a list of one more -more of the following: -.PP -.RS 8 -.nf -NAMED -PTS -SCO -ISC -.fi -.RE -.PP -which represent SVR4 Named Streams pipe, Old-style USL Streams pipe, -SCO XSight Streams pipe, and ISC Streams pipe, respectively. You can -select a single mechanism (e.g. -.IR XLOCAL=NAMED ), -or an ordered list (e.g. \fIXLOCAL="NAMED:PTS:SCO"\fP). -his variable overrides the compiled-in defaults. For SVR4 it is -recommended that -.I NAMED -be the first preference connection. The default setting is -.IR PTS:NAMED:ISC:SCO . -.PP -To globally override the compiled-in defaults, you should define (and -export if using -.B sh -or -.BR ksh ) -.I XLOCAL -globally. If you use startx(1) or xinit(1), the definition should be -at the top of your -.I .xinitrc -file. If you use xdm(1), the definitions should be early on in the -.I __projectroot__/lib/X11/xdm/Xsession -script. -.SH OPTIONS -.B __xservername__ -supports several mechanisms for supplying/obtaining configuration and -run-time parameters: command line options, environment variables, the -__xconfigfile__(__filemansuffix__) configuration files, auto-detection, and -fallback defaults. When the same information is supplied in more than -one way, the highest precedence mechanism is used. The list of mechanisms -is ordered from highest precedence to lowest. Note that not all parameters -can be supplied via all methods. The available command line options -and environment variables (and some defaults) are described here and in -the Xserver(__appmansuffix__) manual page. Most configuration file -parameters, with their defaults, are described in the -__xconfigfile__(__filemansuffix__) manual page. Driver and module specific -configuration parameters are described in the relevant driver or module -manual page. -.PP -In addition to the normal server options described in the -Xserver(__appmansuffix__) manual page, -.B __xservername__ -accepts the following command line switches: -.TP 8 -.BI vt XX -.I XX -specifies the Virtual Terminal device number which -.B __xservername__ -will use. Without this option, -.B __xservername__ -will pick the first available Virtual Terminal that it can locate. This -option applies only to platforms that have virtual terminal support, such -as Linux, BSD, OpenSolaris, SVR3, and SVR4. -.TP -.B \-allowMouseOpenFail -Allow the server to start up even if the mouse device can't be opened -or initialised. This is equivalent to the -.B AllowMouseOpenFail -__xconfigfile__(__filemansuffix__) file option. -.TP 8 -.B \-allowNonLocalXvidtune -Make the VidMode extension available to remote clients. This allows -the xvidtune client to connect from another host. This is equivalent -to the -.B AllowNonLocalXvidtune -__xconfigfile__(__filemansuffix__) file option. By default non-local -connections are not allowed. -.TP 8 -.BI \-bgamma " value" -Set the blue gamma correction. -.I value -must be between 0.1 and 10. -The default is 1.0. Not all drivers support this. See also the -.BR \-gamma , -.BR \-rgamma , -and -.B \-ggamma -options. -.TP 8 -.BI \-bpp " n" -No longer supported. Use -.B \-depth -to set the color depth, and use -.B \-fbbpp -if you really need to force a non-default framebuffer (hardware) pixel -format. -.TP 8 -.BI \-config " file" -Read the server configuration from -.IR file . -This option will work for any file when the server is run as root (i.e, -with real-uid 0), or for files relative to a directory in the config -search path for all other users. -.TP 8 -.BI \-configdir " directory" -Read the server configuration files from -.IR directory . -This option will work for any directory when the server is run as root -(i.e, with real-uid 0), or for directories relative to a directory in the -config directory search path for all other users. -.TP 8 -.B \-configure -When this option is specified, the -.B __xservername__ -server loads all video driver modules, probes for available hardware, -and writes out an initial __xconfigfile__(__filemansuffix__) file based on -what was detected. This option currently has some problems on some -platforms, but in most cases it is a good way to bootstrap the -configuration process. This option is only available when the server -is run as root (i.e, with real-uid 0). -.TP 8 -.BI "\-crt /dev/tty" XX -SCO only. This is the same as the -.B vt -option, and is provided for compatibility with the native SCO X server. -.TP 8 -.BI \-depth " n" -Sets the default color depth. Legal values are 1, 4, 8, 15, 16, and -24. Not all drivers support all values. -.TP 8 -.B \-disableVidMode -Disable the parts of the VidMode extension (used by the xvidtune -client) that can be used to change the video modes. This is equivalent -to the -.B DisableVidModeExtension -__xconfigfile__(__filemansuffix__) file option. -.TP 8 -.B \-fbbpp \fIn\fP -Sets the number of framebuffer bits per pixel. You should only set this -if you're sure it's necessary; normally the server can deduce the correct -value from -.B \-depth -above. Useful if you want to run a depth 24 configuration with a 24 -bpp framebuffer rather than the (possibly default) 32 bpp framebuffer -(or vice versa). Legal values are 1, 8, 16, 24, 32. Not all drivers -support all values. -.TP 8 -.B \-flipPixels -Swap the default values for the black and white pixels. -.TP 8 -.BI \-gamma " value" -Set the gamma correction. -.I value -must be between 0.1 and 10. The default is 1.0. This value is applied -equally to the R, G and B values. Those values can be set independently -with the -.BR \-rgamma , -.BR \-bgamma , -and -.B \-ggamma -options. Not all drivers support this. -.TP 8 -.BI \-ggamma " value" -Set the green gamma correction. -.I value -must be between 0.1 and 10. The default is 1.0. Not all drivers support -this. See also the -.BR \-gamma , -.BR \-rgamma , -and -.B \-bgamma -options. -.TP 8 -.B \-ignoreABI -The -.B __xservername__ -server checks the ABI revision levels of each module that it loads. It -will normally refuse to load modules with ABI revisions that are newer -than the server's. This is because such modules might use interfaces -that the server does not have. When this option is specified, mismatches -like this are downgraded from fatal errors to warnings. This option -should be used with care. -.TP 8 -.B \-isolateDevice \fIbus\-id\fP -Restrict device resets to the device at -.IR bus\-id . -The -.I bus\-id -string has the form -.IB bustype : bus : device : function -(e.g., \(oqPCI:1:0:0\(cq). -At present, only isolation of PCI devices is supported; i.e., this option -is ignored if -.I bustype -is anything other than \(oqPCI\(cq. -.TP 8 -.B \-keeptty -Prevent the server from detaching its initial controlling terminal. -This option is only useful when debugging the server. Not all platforms -support (or can use) this option. -.TP 8 -.BI \-keyboard " keyboard-name" -Use the __xconfigfile__(__filemansuffix__) file -.B InputDevice -section called -.I keyboard-name -as the core keyboard. This option is ignored when the -.B Layout -section specifies a core keyboard. In the absence of both a Layout -section and this option, the first relevant -.B InputDevice -section is used for the core keyboard. -.TP 8 -.BI \-layout " layout-name" -Use the __xconfigfile__(__filemansuffix__) file -.B Layout -section called -.IR layout-name . -By default the first -.B Layout -section is used. -.TP 8 -.BI \-logfile " filename" -Use the file called -.I filename -as the -.B __xservername__ -server log file. The default log file is -.BI __logdir__/__xservername__. n .log -on most platforms, where -.I n -is the display number of the -.B __xservername__ -server. The default may be in a different directory on some platforms. -This option is only available when the server is run as root (i.e, with -real-uid 0). -.TP 8 -.BR \-logverbose " [\fIn\fP]" -Sets the verbosity level for information printed to the -.B __xservername__ -server log file. If the -.I n -value isn't supplied, each occurrence of this option increments the log -file verbosity level. When the -.I n -value is supplied, the log file verbosity level is set to that value. -The default log file verbosity level is 3. -.TP 8 -.BI \-modulepath " searchpath" -Set the module search path to -.IR searchpath . -.I searchpath -is a comma separated list of directories to search for -.B __xservername__ -server modules. This option is only available when the server is run -as root (i.e, with real-uid 0). -.TP 8 -.B \-nosilk -Disable Silken Mouse support. -.TP 8 -.B \-pixmap24 -Set the internal pixmap format for depth 24 pixmaps to 24 bits per pixel. -The default is usually 32 bits per pixel. There is normally little -reason to use this option. Some client applications don't like this -pixmap format, even though it is a perfectly legal format. This is -equivalent to the -.B Pixmap -__xconfigfile__(__filemansuffix__) file option. -.TP 8 -.B \-pixmap32 -Set the internal pixmap format for depth 24 pixmaps to 32 bits per pixel. -This is usually the default. This is equivalent to the -.B Pixmap -__xconfigfile__(__filemansuffix__) file option. -.TP 8 -.BI \-pointer " pointer-name" -Use the __xconfigfile__(__filemansuffix__) file -.B InputDevice -section called -.I pointer-name -as the core pointer. This option is ignored when the -.B Layout -section specifies a core pointer. In the absence of both a Layout -section and this option, the first relevant -.B InputDevice -section is used for the core pointer. -.TP 8 -.B \-quiet -Suppress most informational messages at startup. The verbosity level -is set to zero. -.TP 8 -.BI \-rgamma " value" -Set the red gamma correction. -.I value -must be between 0.1 and 10. The default is 1.0. Not all drivers support -this. See also the -.BR \-gamma , -.BR \-bgamma , -and -.B \-ggamma -options. -.TP 8 -.BI \-screen " screen-name" -Use the __xconfigfile__(__filemansuffix__) file -.B Screen -section called -.IR screen-name . -By default the screens referenced by the default -.B Layout -section are used, or the first -.B Screen -section when there are no -.B Layout -sections. -.TP 8 -.B \-showconfig -This is the same as the -.B \-version -option, and is included for compatibility reasons. It may be removed -in a future release, so the -.B \-version -option should be used instead. -.TP 8 -.B \-showDefaultModulePath -Print out the default module path the server was compiled with. -.TP 8 -.B \-showDefaultLibPath -Print out the path libraries should be installed to. -.TP 8 -.B \-showopts -For each driver module installed, print out the list of options and their -argument types. -.TP 8 -.BI \-weight " nnn" -Set RGB weighting at 16 bpp. The default is 565. This applies only to -those drivers which support 16 bpp. -.TP 8 -.BR \-verbose " [\fIn\fP]" -Sets the verbosity level for information printed on stderr. If the -.I n -value isn't supplied, each occurrence of this option increments the -verbosity level. When the -.I n -value is supplied, the verbosity level is set to that value. The default -verbosity level is 0. -.TP 8 -.B \-version -Print out the server version, patchlevel, release date, the operating -system/platform it was built on, and whether it includes module loader -support. -.SH "KEYBOARD" -.PP -The -.B __xservername__ -server is normally configured to recognize various special combinations -of key presses that instruct the server to perform some action, rather -than just sending the key press event to a client application. These actions -depend on the XKB keymap loaded by a particular keyboard device and may or -may not be available on a given configuration. -.PP -The following key combinations are commonly part of the default XKEYBOARD -keymap. -.TP 8 -.B Ctrl+Alt+Backspace -Immediately kills the server -- no questions asked. It can be disabled by -setting the -.B DontZap -__xconfigfile__(__filemansuffix__) file option to a TRUE value. -.PP -.RS 8 -It should be noted that zapping is triggered by the -.B Terminate_Server -action in the keyboard map. This action is not part of the default keymaps -but can be enabled with the XKB option -.B \*qterminate:ctrl_alt_bksp\*q. -.RE -.TP 8 -.B Ctrl+Alt+Keypad-Plus -Change video mode to next one specified in the configuration file. -This can be disabled with the -.B DontZoom -__xconfigfile__(__filemansuffix__) file option. -.TP 8 -.B Ctrl+Alt+Keypad-Minus -Change video mode to previous one specified in the configuration file. -This can be disabled with the -.B DontZoom -__xconfigfile__(__filemansuffix__) file option. -.TP 8 -.B Ctrl+Alt+F1...F12 -For systems with virtual terminal support, these keystroke -combinations are used to switch to virtual terminals 1 through 12, -respectively. This can be disabled with the -.B DontVTSwitch -__xconfigfile__(__filemansuffix__) file option. -.SH CONFIGURATION -.B __xservername__ -typically uses a configuration file called -.B __xconfigfile__ -and configuration files with the suffix -.I .conf -in a directory called -.B __xconfigdir__ -for its initial setup. -Refer to the __xconfigfile__(__filemansuffix__) manual page for information -about the format of this file. -.PP -.B __xservername__ -has a mechanism for automatically generating a built-in configuration -at run-time when no -.B __xconfigfile__ -file or -.B __xconfigdir__ -files are present. The current version of this automatic configuration -mechanism works in two ways. -.PP -The first is via enhancements that have made many components of the -.B __xconfigfile__ -file optional. This means that information that can be probed or -reasonably deduced doesn't need to be specified explicitly, greatly -reducing the amount of built-in configuration information that needs to -be generated at run-time. -.PP -The second is to have "safe" fallbacks for most configuration information. -This maximises the likelihood that the -.B __xservername__ -server will start up in some usable configuration even when information -about the specific hardware is not available. -.PP -The automatic configuration support for __xservername__ is work in progress. -It is currently aimed at the most popular hardware and software platforms -supported by __xservername__. Enhancements are planned for future releases. -.SH FILES -The -.B __xservername__ -server config files can be found in a range of locations.

When the same information is supplied in more +than one way, the highest precedence mechanism is used. The list of +mechanisms is ordered from highest precedence to lowest. Note that not +all parameters can be supplied via all methods. The available command +line options and environment variables (and some defaults) are +described in the Xserver(__appmansuffix__) and +__xservername__(__appmansuffix__) manual pages. Most configuration file +parameters, with their defaults, are described below. Driver and module +specific configuration parameters are described in the relevant driver +or module manual page. +.SH DESCRIPTION +.B __xservername__ +uses a configuration file called +.I __xconfigfile__ +and files ending in the suffix +.I .conf +from the directory +.I __xconfigdir__ +for its initial setup. +The +.I __xconfigfile__ +configuration file is searched for in the following places when the +server is started as a normal user: +.PP +.RS 4 +.nf +.IR /etc/X11/ +.IR __projectroot__/etc/X11/ +.IB /etc/X11/ $XORGCONFIG +.IB __projectroot__/etc/X11/ $XORGCONFIG +.I /etc/X11/__xconfigfile__ +.I /etc/__xconfigfile__ +.IR __projectroot__/etc/X11/__xconfigfile__. +.I __projectroot__/etc/X11/__xconfigfile__ +.IR __projectroot__/lib/X11/__xconfigfile__. +.I __projectroot__/lib/X11/__xconfigfile__ +.fi +.RE +.PP +where +.I +is a relative path (with no \(lq..\(rq components) specified with the +.B \-config +command line option, +.B $XORGCONFIG +is the relative path (with no \(lq..\(rq components) specified by that +environment variable, and +.I +is the machine's hostname as reported by +.BR gethostname (__libmansuffix__). +.PP +When the __xservername__ server is started by the \(lqroot\(rq user, the config file +search locations are as follows: +.PP +.RS 4 +.nf + +.IR /etc/X11/ +.IR __projectroot__/etc/X11/ +.B $XORGCONFIG +.IB /etc/X11/ $XORGCONFIG +.IB __projectroot__/etc/X11/ $XORGCONFIG +.I /etc/X11/__xconfigfile__ +.I /etc/__xconfigfile__ +.IR __projectroot__/etc/X11/__xconfigfile__. +.I __projectroot__/etc/X11/__xconfigfile__ +.IR __projectroot__/lib/X11/__xconfigfile__. +.I __projectroot__/lib/X11/__xconfigfile__ +.fi +.RE +.PP +where +.I +is the path specified with the +.B \-config +command line option (which may be absolute or relative), +.B $XORGCONFIG +is the path specified by that +environment variable (absolute or relative), +.B $HOME +is the path specified by that environment variable (usually the home +directory), and +.I +is the machine's hostname as reported by +.BR gethostname (__libmansuffix__). +.PP +Additional configuration files are searched for in the following +directories when the server is started as a normal user: +.PP +.RS 4 +.nf +.IR /etc/X11/ +.IR __sysconfdir__/X11/ +.I /etc/X11/__xconfigdir__ +.I __sysconfdir__/X11/__xconfigdir__ +.fi +.RE +.PP +where +.I +is a relative path (with no \(lq..\(rq components) specified with the +.B \-configdir +command line option. +.PP +When the __xservername__ server is started by the \(lqroot\(rq user, the +config directory search locations are as follows: +.PP +.RS 4 +.nf + +.IR /etc/X11/ +.IR __sysconfdir__/X11/ +.I /etc/X11/__xconfigdir__ +.I __sysconfdir__/X11/__xconfigdir__ +.fi +.RE +.PP +where +.I +is the path specified with the +.B \-configdir +command line option (which may be absolute or relative). +.PP +Finally, configuration files will also be searched for in directories +reserved for system use.

"speed\-8 speed\-16 speed\-24 speed\-32" +This optional entry specifies the RAMDAC speed rating (which is usually +printed on the RAMDAC chip). +The speed is in MHz. +When one value is given, it applies to all framebuffer pixel sizes. +When multiple values are given, they apply to the framebuffer pixel sizes +8, 16, 24 and 32 respectively. +This is not used by many drivers, and only needs to be specified when the +speed rating of the RAMDAC is different from the defaults built in to +driver, or when the driver can't auto-detect the correct defaults. +Don't specify it unless the driver-specific documentation recommends that you +do. +.TP 7 +.BI "Clocks " "clock ..." +specifies the pixel that are on your graphics board. +The clocks are in MHz, and may be specified as a floating point number. +The value is stored internally to the nearest kHz. +The ordering of the clocks is important. +It must match the order in which they are selected on the graphics board. +Multiple +.B Clocks +lines may be specified, and each is concatenated to form the list. +Most drivers do not use this entry, and it is only required for some older +boards with non-programmable

clock chip type on graphics +boards which have a programmable clock generator. +Only a few __xservername__ drivers support programmable clock chips. +For details, see the appropriate driver manual page. +.TP 7 +.BI "VideoRam " "mem" +This optional entry specifies the amount of video ram that is installed +on the graphics board. +This is measured in kBytes. +In most cases this is not required because the __xservername__ server probes +the graphics board to determine this quantity. +The driver-specific documentation should indicate when it might be needed. +.TP 7 +.BI "BiosBase " "baseaddress" +This optional entry specifies the base address of the video BIOS for +the VGA board. +This address is normally auto-detected, and should only be specified if the +driver-specific documentation recommends it. +.TP 7 +.BI "MemBase " "baseaddress" +This optional entry specifies the memory base address of a graphics +board's linear frame buffer. +This entry is not used by many drivers, and it should only be specified if +the driver-specific documentation recommends it. +.TP 7 +.BI "IOBase " "baseaddress" +This optional entry specifies the IO base address. +This entry is not used by many drivers, and it should only be specified if +the driver-specific documentation recommends it. +.TP 7 +.BI "ChipID " "id" +This optional entry specifies a numerical ID representing the

__appmansuffix__ __xorgversion__ -.SH NAME -Xnest \- a nested X server -.SH SYNOPSIS -.B Xnest -[ -.I options -] -.SH DESCRIPTION -.B Xnest -is both an X client and an X server. -.B Xnest -is a client of the real server which manages windows and graphics requests on -its behalf. -.B Xnest -is a server to its own clients. -.B Xnest -manages windows and graphics requests on their behalf. -To these clients, -.B Xnest -appears to be a conventional server. -.SH OPTIONS -.B Xnest -supports all standard options of the sample server implementation. -For more details, please see -.BR Xserver (__appmansuffix__). -The following additional arguments are supported as well. -.TP -.BI "\-display " string -This option specifies the display name of the real server that -.B Xnest -should try to connect to. -If it is not provided on the command line, -.B Xnest -will read the -.I DISPLAY -environment variable in order to find out this information. -.TP -.B \-sync -This option tells -.B Xnest -to synchronize its window and graphics operations with the real server. -This is a useful option for debugging, but it will slow down -.BR Xnest 's -performance considerably. -It should not be used unless absolutely necessary. -.TP -.B \-full -This option tells -.B Xnest -to utilize full regeneration of real server objects and reopen a new connection -to the real server each time the nested server regenerates. -The sample server implementation regenerates all objects in the server when the -last client of this server terminates. -When this happens, -.B Xnest -by default maintains the same top-level window and the same real server -connection in each new generation. -If the user selects full regeneration, even the top-level window and the -connection to the real server will be regenerated for each server generation. -.TP -.BI "\-class " string -This option specifies the default visual class of the nested server. -It is similar to the -.B \-cc -option from the set of standard options except that it will accept a string -rather than a number for the visual class specification. -The -.I string -must be one of the following six values: -.BR StaticGray , -.BR GrayScale , -.BR StaticColor , -.BR PseudoColor , -.BR TrueColor , -or -.BR DirectColor . -If both the -.B \-class -and -.B \-cc -options are specified, the last instance of either option takes precedence. -The class of the default visual of the nested server need not be the same as the -class of the default visual of the real server, but it must be supported by the -real server. -Use -.BR xdpyinfo (__appmansuffix__) -to obtain a list of supported visual classes on the real server before starting -.BR Xnest . -If the user chooses a static class, all the colors in the default color map will -be preallocated. -If the user chooses a dynamic class, colors in the default color map will be -available to individual clients for allocation. -.TP -.BI "\-depth " int -This option specifies the default visual depth of the nested server. -The depth of the default visual of the nested server need not be the same as the -depth of the default visual of the real server, but it must be supported by the -real server. -Use -.BR xdpyinfo (__appmansuffix__) -to obtain a list of supported visual depths on the real server before starting -.BR Xnest . -.TP -.B \-sss -This option tells -.B Xnest -to use the software screen saver. -By default, -.B Xnest -will use the screen saver that corresponds to the hardware screen saver in the -real server. -Of course, even this screen saver is software-generated since -.B Xnest -does not control any actual hardware. -However, it is treated as a hardware screen saver within the sample server code. -.TP -.B \-geometry \fIW\fBx\fIH\fB+\fIX\fB+\fIY\fP -This option specifies the geometry parameters for the top-level -.B Xnest -window. -See \(lqGEOMETRY SPECIFICATIONS\(rq in -.BR X (__miscmansuffix__) -for a discusson of this option's syntax. -This window corresponds to the root window of the nested server. -The width -.I W -and height -.I H -specified with this option will be the maximum width and height of each -top-level -.B Xnest -window. -.B Xnest -will allow the user to make any top-level window smaller, but it will not -actually change the size of the nested server root window. -.B Xnest -does not yet support the RANDR extension for resizing, rotation, and reflection -of the root window. -If this option is not specified, -.B Xnest -will choose -.I W -and -.I H -to be 3/4ths the dimensions of the root window of the real server. -.TP -.BI "\-bw " int -This option specifies the border width of the top-level -.B Xnest -window. -The integer parameter -.I int -must be positive. -The default border width is 1. -.TP -.BI "\-name " string -This option specifies the name of the top-level -.B Xnest -window as -.IR string . -The default value is the program name. -.TP -.BI "\-scrns " int -This option specifies the number of screens to create in the nested server. -For each screen, -.B Xnest -will create a separate top-level window. -Each screen is referenced by the number after the dot in the client display name -specification. -For example, -.B xterm \-display :1.1 -will open an -.BR xterm (__appmansuffix__) -client in the nested server with the display number -.B :1 -on the second screen. -The number of screens is limited by the hard-coded constant in the server sample -code, which is usually 3. -.TP -.B \-install -This option tells -.B Xnest -to do its own color map installation by bypassing the real window manager. -For it to work properly, the user will probably have to temporarily quit the -real window manager. -By default, -.B Xnest -will keep the nested client window whose color map should be installed in the -real server in the -.I WM_COLORMAP_WINDOWS -property of the top-level -.B Xnest -window. -If this color map is of the same visual type as the root window of the nested -server, -.B Xnest -will associate this color map with the top-level -.B Xnest -window as well. -Since this does not have to be the case, window managers should look primarily -at the -.I WM_COLORMAP_WINDOWS -property rather than the color map associated with the top-level -.B Xnest -window. -.\" Is the following still true? This sentence is several years old. -Unfortunately, window managers are not very good at doing that yet so this -option might come in handy. -.TP -.BI "\-parent " window_id -This option tells -.B Xnest -to use -.I window_id -as the root window instead of creating a window. -.\" XRX is dead, dead, dead. -.\" This option is used by the xrx xnestplugin. -.SH "EXTENDED DESCRIPTION" -Starting up -.B Xnest -is just as simple as starting up -.BR xclock (__appmansuffix__) -from a terminal emulator. -If a user wishes to run -.B Xnest -on the same -workstation as the real server, it is important that the nested server is given -its own listening socket address. -Therefore, if there is a server already running on the user's workstation, -.B Xnest -will have to be started up with a new display number. -Since there is usually no more than one server running on a workstation, -specifying -.RB \(oq "Xnest :1" \(cq -on the command line will be sufficient for most users. -For each server running on the workstation, the display number needs to be -incremented by one. -Thus, if you wish to start another -.BR Xnest , -you will need to type -.RB \(oq "Xnest :2" \(cq -on the command line. -.PP -To run clients in the nested server, each client needs to be given the same -display number as the nested server. -For example, -.RB \(oq "xterm \-display :1" \(cq -will start up an -.B xterm -process in the first nested server -and -.RB \(oq "xterm \-display :2" \(cq -will start an -.B xterm -in the second nested server from the example above. -Additional clients can be started from these -.BR xterm s -in each nested server. -.SS "Xnest as a client" -.B Xnest -behaves and looks to the real server and other real clients as another real -client. -It is a rather demanding client, however, since almost any window or graphics -request from a nested client will result in a window or graphics request from -.B Xnest -to the real server. -Therefore, it is desirable that -.B Xnest -and the real server are on a local network, or even better, on the same machine. -.B Xnest -assumes that the real server supports the SHAPE extension. -There is no way to turn off this assumption dynamically. -.B Xnest -can be compiled without the SHAPE extension built in, in which case the real -server need not support it. -Dynamic SHAPE extension selection support may be considered in further -development of -.BR Xnest . -.PP -Since -.B Xnest -need not use the same default visual as the the real server, the top-level -window of the -.B Xnest -client always has its own color map. -This implies that other windows' colors will not be displayed properly while the -keyboard or pointer focus is in the -.B Xnest -window, unless the real server has support for more than one installed color map -at any time. -The color map associated with the top window of the -.B Xnest -client need not be the appropriate color map that the nested server wants -installed in the real server. -In the case that a nested client attempts to install a color map of a different -visual from the default visual of the nested server, -.B Xnest -will put the top window of this nested client and all other top windows of the -nested clients that use the same color map into the -.I WM_COLORMAP_WINDOWS -property of the top-level -.B Xnest -window on the real server. -Thus, it is important that the real window manager that manages the -.B Xnest -top-level window looks at the -.I WM_COLORMAP_WINDOWS -property rather than the color map associated with the top-level -.B Xnest -window. -Since most window managers don't yet appear to implement this convention -properly, -.B Xnest -can optionally do direct installation of color maps into the real server -bypassing the real window manager. -If the user chooses this option, it is usually necessary to temporarily disable -the real window manager since it will interfere with the -.B Xnest -scheme of color map installation. -.PP -Keyboard and pointer control procedures of the nested server change the keyboard -and pointer control parameters of the real server. -Therefore, after -.B Xnest -is started up, it will change the keyboard and pointer controls of the real -server to its own internal defaults. -.SS "Xnest as a server" -.B Xnest -as a server looks exactly like a real server to its own clients. -For the clients, there is no way of telling if they are

__appmansuffix__ __xorgversion__ +.SH NAME +Xnest \- a nested X server +.SH SYNOPSIS +.B Xnest +[ +.I options +] +.SH DESCRIPTION +.B Xnest +is both an X client and an X server. +.B Xnest +is a client of the real server which manages windows and graphics requests on +its behalf. +.B Xnest +is a server to its own clients. +.B Xnest +manages windows and graphics requests on their behalf. +To these clients, +.B Xnest +appears to be a conventional server. +.SH OPTIONS +.B Xnest +supports all standard options of the sample server implementation. +For more details, please see +.BR Xserver (__appmansuffix__). +The following additional arguments are supported as well. +.TP +.BI "\-display " string +This option specifies the display name of the real server that +.B Xnest +should try to connect to. +If it is not provided on the command line, +.B Xnest +will read the +.I DISPLAY +environment variable in order to find out this information. +.TP +.B \-sync +This option tells +.B Xnest +to synchronize its window and graphics operations with the real server. +This is a useful option for debugging, but it will slow down +.BR Xnest 's +performance considerably. +It should not be used unless absolutely necessary. +.TP +.B \-full +This option tells +.B Xnest +to utilize full regeneration of real server objects and reopen a new connection +to the real server each time the nested server regenerates. +The sample server implementation regenerates all objects in the server when the +last client of this server terminates. +When this happens, +.B Xnest +by default maintains the same top-level window and the same real server +connection in each new generation. +If the user selects full regeneration, even the top-level window and the +connection to the real server will be regenerated for each server generation. +.TP +.BI "\-class " string +This option specifies the default visual class of the nested server. +It is similar to the +.B \-cc +option from the set of standard options except that it will accept a string +rather than a number for the visual class specification. +The +.I string +must be one of the following six values: +.BR StaticGray , +.BR GrayScale , +.BR StaticColor , +.BR PseudoColor , +.BR TrueColor , +or +.BR DirectColor . +If both the +.B \-class +and +.B \-cc +options are specified, the last instance of either option takes precedence. +The class of the default visual of the nested server need not be the same as the +class of the default visual of the real server, but it must be supported by the +real server. +Use +.BR xdpyinfo (__appmansuffix__) +to obtain a list of supported visual classes on the real server before starting +.BR Xnest . +If the user chooses a static class, all the colors in the default color map will +be preallocated. +If the user chooses a dynamic class, colors in the default color map will be +available to individual clients for allocation. +.TP +.BI "\-depth " int +This option specifies the default visual depth of the nested server. +The depth of the default visual of the nested server need not be the same as the +depth of the default visual of the real server, but it must be supported by the +real server. +Use +.BR xdpyinfo (__appmansuffix__) +to obtain a list of supported visual depths on the real server before starting +.BR Xnest . +.TP +.B \-sss +This option tells +.B Xnest +to use the software screen saver. +By default, +.B Xnest +will use the screen saver that corresponds to the hardware screen saver in the +real server. +Of course, even this screen saver is software-generated since +.B Xnest +does not control any actual hardware. +However, it is treated as a hardware screen saver within the sample server code. +.TP +.B \-geometry \fIW\fBx\fIH\fB+\fIX\fB+\fIY\fP +This option specifies the geometry parameters for the top-level +.B Xnest +window. +See \(lqGEOMETRY SPECIFICATIONS\(rq in +.BR X (__miscmansuffix__) +for a discusson of this option's syntax. +This window corresponds to the root window of the nested server. +The width +.I W +and height +.I H +specified with this option will be the maximum width and height of each +top-level +.B Xnest +window. +.B Xnest +will allow the user to make any top-level window smaller, but it will not +actually change the size of the nested server root window. +.B Xnest +does not yet support the RANDR extension for resizing, rotation, and reflection +of the root window. +If this option is not specified, +.B Xnest +will choose +.I W +and +.I H +to be 3/4ths the dimensions of the root window of the real server. +.TP +.BI "\-bw " int +This option specifies the border width of the top-level +.B Xnest +window. +The integer parameter +.I int +must be positive. +The default border width is 1. +.TP +.BI "\-name " string +This option specifies the name of the top-level +.B Xnest +window as +.IR string . +The default value is the program name. +.TP +.BI "\-scrns " int +This option specifies the number of screens to create in the nested server. +For each screen, +.B Xnest +will create a separate top-level window. +Each screen is referenced by the number after the dot in the client display name +specification. +For example, +.B xterm \-display :1.1 +will open an +.BR xterm (__appmansuffix__) +client in the nested server with the display number +.B :1 +on the second screen. +The number of screens is limited by the hard-coded constant in the server sample +code, which is usually 3. +.TP +.B \-install +This option tells +.B Xnest +to do its own color map installation by bypassing the real window manager. +For it to work properly, the user will probably have to temporarily quit the +real window manager. +By default, +.B Xnest +will keep the nested client window whose color map should be installed in the +real server in the +.I WM_COLORMAP_WINDOWS +property of the top-level +.B Xnest +window. +If this color map is of the same visual type as the root window of the nested +server, +.B Xnest +will associate this color map with the top-level +.B Xnest +window as well. +Since this does not have to be the case, window managers should look primarily +at the +.I WM_COLORMAP_WINDOWS +property rather than the color map associated with the top-level +.B Xnest +window. +.\" Is the following still true? This sentence is several years old. +Unfortunately, window managers are not very good at doing that yet so this +option might come in handy. +.TP +.BI "\-parent " window_id +This option tells +.B Xnest +to use +.I window_id +as the root window instead of creating a window. +.\" XRX is dead, dead, dead. +.\" This option is used by the xrx xnestplugin. +.SH "EXTENDED DESCRIPTION" +Starting up +.B Xnest +is just as simple as starting up +.BR xclock (__appmansuffix__) +from a terminal emulator. +If a user wishes to run +.B Xnest +on the same +workstation as the real server, it is important that the nested server is given +its own listening socket address. +Therefore, if there is a server already running on the user's workstation, +.B Xnest +will have to be started up with a new display number. +Since there is usually no more than one server running on a workstation, +specifying +.RB \(oq "Xnest :1" \(cq +on the command line will be sufficient for most users. +For each server running on the workstation, the display number needs to be +incremented by one. +Thus, if you wish to start another +.BR Xnest , +you will need to type +.RB \(oq "Xnest :2" \(cq +on the command line. +.PP +To run clients in the nested server, each client needs to be given the same +display number as the nested server. +For example, +.RB \(oq "xterm \-display :1" \(cq +will start up an +.B xterm +process in the first nested server +and +.RB \(oq "xterm \-display :2" \(cq +will start an +.B xterm +in the second nested server from the example above. +Additional clients can be started from these +.BR xterm s +in each nested server. +.SS "Xnest as a client" +.B Xnest +behaves and looks to the real server and other real clients as another real +client. +It is a rather demanding client, however, since almost any window or graphics +request from a nested client will result in a window or graphics request from +.B Xnest +to the real server. +Therefore, it is desirable that +.B Xnest +and the real server are on a local network, or even better, on the same machine. +.B Xnest +assumes that the real server supports the SHAPE extension. +There is no way to turn off this assumption dynamically. +.B Xnest +can be compiled without the SHAPE extension built in, in which case the real +server need not support it. +Dynamic SHAPE extension selection support may be considered in further +development of +.BR Xnest . +.PP +Since +.B Xnest +need not use the same default visual as the the real server, the top-level +window of the +.B Xnest +client always has its own color map. +This implies that other windows' colors will not be displayed properly while the +keyboard or pointer focus is in the +.B Xnest +window, unless the real server has support for more than one installed color map +at any time. +The color map associated with the top window of the +.B Xnest +client need not be the appropriate color map that the nested server wants +installed in the real server. +In the case that a nested client attempts to install a color map of a different +visual from the default visual of the nested server, +.B Xnest +will put the top window of this nested client and all other top windows of the +nested clients that use the same color map into the +.I WM_COLORMAP_WINDOWS +property of the top-level +.B Xnest +window on the real server. +Thus, it is important that the real window manager that manages the +.B Xnest +top-level window looks at the +.I WM_COLORMAP_WINDOWS +property rather than the color map associated with the top-level +.B Xnest +window. +Since most window managers don't yet appear to implement this convention +properly, +.B Xnest +can optionally do direct installation of color maps into the real server +bypassing the real window manager. +If the user chooses this option, it is usually necessary to temporarily disable +the real window manager since it will interfere with the +.B Xnest +scheme of color map installation. +.PP +Keyboard and pointer control procedures of the nested server change the keyboard +and pointer control parameters of the real server. +Therefore, after +.B Xnest +is started up, it will change the keyboard and pointer controls of the real +server to its own internal defaults. +.SS "Xnest as a server" +.B Xnest +as a server looks exactly like a real server to its own clients. +For the clients, there is no way of telling if they are running on a real or a +nested server. +.PP +As already mentioned, +.B Xnest +is a very user-friendly server when it comes to customization. +.B Xnest +will pick up a number of command-line arguments that can configure its default +visual class and depth, number of screens, etc. +.PP +The only apparent intricacy from the users' perspective about using +.B Xnest +as a server is the selection of fonts. +.B Xnest +manages fonts by loading them locally and then passing the font name to the real +server and asking it to load that font remotely. +This approach avoids the overload of sending the glyph bits across the network +for every text operation, although it is really a bug. +The consequence of this approach is that the user will have to worry about two +different font paths \(em a local

The X11 root window is not displayed in rootless mode as Mac +OS X handles the desktop background. +.SH CUSTOMIZATION +\fIXquartz\fP can be customized using the defaults(1) command. The available options are: +.TP 8 +.B defaults write __laucnd_id_prefix__.X11 enable_fake_buttons -boolean true +Emulates a 3 button mouse using modifier keys.

See Xsecurity(__miscmansuffix__). +.TP 8 +.B defaults write __laucnd_id_prefix__.X11 nolisten_tcp -boolean false +This will tell the server to listen and accept TCP connections. Doing this without enabling +xauth is a possible security concern. See Xsecurity(__miscmansuffix__). +.TP 8 +.B defaults write __laucnd_id_prefix__.X11 enable_system_beep -boolean false +Don't use the standard system beep effect for X11 alerts. +.TP 8 +.B defaults write __laucnd_id_prefix__.X11 enable_key_equivalents -boolean false +Disable menu keyboard equivalents while X11 windows are focused. +.TP 8 +.B defaults write __laucnd_id_prefix__.X11 depth \fIdepth\fP +Specifies the color bit depth to use.

It updates the NSPasteboard whenever a new X11 selection is made (rather than requiring you to hit cmd-c to copy the selection to the NSPasteboard). Since the X11 protocol does not require applications to send notification when they change selection, this might not work in all cases (if you run into this problem, try selecting text in another application first, then selecting the text you want). +.TP 8 +.B defaults write __laucnd_id_prefix__.X11 enable_test_extensions -boolean true +This option defaults to false and is only accessible through the command line.

-\fIXWin\fP is an X Server for the X Window System on the Cygwin environment -running on Microsoft Windows. - - -.SH MODES -\fIXWin\fP can operate in 3 different modes: -.br -* \fISingle Window\fP: This is the default mode. Each X screen -appears as a single \fIWindows\fP window and all X windows are contained -within this window. -(In X terminology, the \fIWindows\fP window contains the root window for -the screen) -.br -* \fIMulti-Window\fP: In this mode \fIXWin\fP uses its own integrated -window manager in order to handle the top-level X windows, in such a -way that they appear as normal \fIWindows\fP windows. -.br -* \fIRootless\fP: In this mode the X server works in a window -containing the whole screen but this root window (traditionally covered with an X hatch -pattern) is hidden from view, so only top-level X windows are seen. - -.SH OPTIONS -In addition to the normal server options described in the \fIXserver(1)\fP -manual page, \fIXWin\fP accepts the following command line switches, -\fIall\fP of which are optional: - -.SH OPTIONS CONTROLLING WINDOWING MODE -Only one of these options may be specified. -.TP 8 -.B (default) -Windowed or rooted mode. -Each X screen appears as a single \fIWindows\fP window and all X windows are -contained within those windows. -.TP 8 -.B \-multiwindow -Each top-level X window appears in its own \fIWindows\fP window. -Also start the integrated \fIWindows\fP-based window manager. -.TP 8 -.B \-rootless -Run the server in rootless mode. -The X server works on a window covering the whole screen but the root window -is hidden from view. -.TP 8 -.B \-mwextwm -Experimental. -The mode combines \fB\-rootless\fP mode drawing with native \fIWindows\fP -window frames managed by the experimental external window manager \fIxwinwm\fP. -.PP -\fBNOTE:\fP \fI-multiwindow\fP mode uses its own internal window manager. -All other modes require an external window manager in order to move, resize, and perform other -operations on the individual X windows. - -.SH OPTIONS FOR SPECIFYING X SCREENS -An X display may be composed of multiple screens. -The default behaviour is to create a single screen 0 that is roughly the -size of useful area of the primary monitor (allowing for any window -decorations and the task-bar). - -Screen specific parameters, such as \fB\-fullscreen\fP, can be applied as a -default to all screens by placing those screen specific parameters -before any \fB\-screen\fP parameter.

Each X screen +appears as a single \fIWindows\fP window and all X windows are contained +within this window. +(In X terminology, the \fIWindows\fP window contains the root window for +the screen) +.br +* \fIMulti-Window\fP: In this mode \fIXWin\fP uses its own integrated +window manager in order to handle the top-level X windows, in such a +way that they appear as normal \fIWindows\fP windows. +.br +* \fIRootless\fP: In this mode the X server works in a window +containing the whole screen but this root window (traditionally covered with an X hatch +pattern) is hidden from view, so only top-level X windows are seen. + +.SH OPTIONS +In addition to the normal server options described in the \fIXserver(1)\fP +manual page, \fIXWin\fP accepts the following command line switches, +\fIall\fP of which are optional: + +.SH OPTIONS CONTROLLING WINDOWING MODE +Only one of these options may be specified. +.TP 8 +.B (default) +Windowed or rooted mode. +Each X screen appears as a single \fIWindows\fP window and all X windows are +contained within those windows. +.TP 8 +.B \-multiwindow +Each top-level X window appears in its own \fIWindows\fP window. +Also start the integrated \fIWindows\fP-based window manager. +.TP 8 +.B \-rootless +Run the server in rootless mode. +The X server works on a window covering the whole screen but the root window +is hidden from view. +.TP 8 +.B \-mwextwm +Experimental. +The mode combines \fB\-rootless\fP mode drawing with native \fIWindows\fP +window frames managed by the experimental external window manager \fIxwinwm\fP. +.PP +\fBNOTE:\fP \fI-multiwindow\fP mode uses its own internal window manager. +All other modes require an external window manager in order to move, resize, and perform other +operations on the individual X windows. + +.SH OPTIONS FOR SPECIFYING X SCREENS +An X display may be composed of multiple screens. +The default behaviour is to create a single screen 0 that is roughly the +size of useful area of the primary monitor (allowing for any window +decorations and the task-bar). + +Screen specific parameters, such as \fB\-fullscreen\fP, can be applied as a +default to all screens by placing those screen specific parameters +before any \fB\-screen\fP parameter.
