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". Other values may include "sgi" and "sun". -.sp -.TP 8 -.B XkbModel -Defaults to "pc101". When used with "xfree86" rules, other values may -include "pc102", "pc104", "pc105", "microsoft", and many others. When -used with "sun" rules, other values may include "type4" and "type5". -.sp -.TP 8 -.B XkbLayout -Defaults to "us". Other country codes and "dvorak" are usually -available. -.sp -.TP 8 -.B XkbVariant -Defaults to "". -.sp -.TP 8 -.B XkbOptions -Defaults to "". -.RE -.SH "CONFIGURATION FILE GRAMMAR" -The following words and tokens are reserved: -.RS -.B virtual -.B display -.B wall -.B option -.B param -.B { -.B } -.B ; -.B # -.RE -.PP -Comments start with a -.B # -mark and extend to the end of the line. They may appear anywhere.

The name of a display should be standard X display -name, although no checking is performed (e.g., "machine:0"). -.PP -For names, double quotes are optional unless the name is reserved or -contains spaces. -.PP -The first dimension following -.B wall -is the dimension for tiling (e.g., 2x4 or 4x4). 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. The second -geometry, which is always preceeded by a slash, is the geometry of the -root window. By default, the root window has the same geometry as the -screen window. -.PP -The -.B option -line can be used to specify any command-line options (e.g., -.BR \-input ). -(It cannot be used to specify the name of the front-end display.) The -option line is processed once at server startup, just line command line -options. This behavior may be unexpected. -.SH "CONFIGURATION FILE EXAMPLES" -Two displays being used for a desktop may be specified in any of the -following formats: -.RS -.nf -virtual example0 { - display d0:0 1280x1024 @0x0; - display d1:0 1280x1024 @1280x0; -} -.sp -virtual example1 { - display d0:0 1280x1024; - display d1:0 @1280x0; -} -.sp -virtual example2 { - display "d0:0"; - display "d1:0" @1280x0; -} -.sp -virtual example3 { wall 2x1 d0:0 d1:0; } -.fi -.RE -A 4x4 wall of 16 total displays could be specified as follows (if no -tiling dimension is specified, an approximate square is used): -.RS -.nf -virtual example4 { - wall d0:0 d1:0 d2:0 d3:0 - d4:0 d5:0 d6:0 d7:0 - d8:0 d9:0 da:0 db:0 - dc:0 dd:0 de:0 df:0; -} -.fi -.RE -.SH "FONT PATHS" -The font path used by the -.I Xdmx -front-end server will be propagated to each back-end server,which -requires that each back-end server have access to the exact same font -paths as the front-end 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.
