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/ <cmdline> -.IR __projectroot__/etc/X11/ <cmdline> -.IB /etc/X11/ $XORGCONFIG -.IB __projectroot__/etc/X11/ $XORGCONFIG -.I /etc/X11/__xconfigfile__ -.I /etc/__xconfigfile__ -.IR __projectroot__/etc/X11/__xconfigfile__. <hostname> -.I __projectroot__/etc/X11/__xconfigfile__ -.IR __projectroot__/lib/X11/__xconfigfile__. <hostname> -.I __projectroot__/lib/X11/__xconfigfile__ -.fi -.RE -.PP -where -.I <cmdline> -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 <hostname> -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 -<cmdline> -.IR /etc/X11/ <cmdline> -.IR __projectroot__/etc/X11/ <cmdline> -.B $XORGCONFIG -.IB /etc/X11/ $XORGCONFIG -.IB __projectroot__/etc/X11/ $XORGCONFIG -.I /etc/X11/__xconfigfile__ -.I /etc/__xconfigfile__ -.IR __projectroot__/etc/X11/__xconfigfile__. <hostname> -.I __projectroot__/etc/X11/__xconfigfile__ -.IR __projectroot__/lib/X11/__xconfigfile__. <hostname> -.I __projectroot__/lib/X11/__xconfigfile__ -.fi -.RE -.PP -where -.I <cmdline> -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 <hostname> -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/ <cmdline> -.IR __sysconfdir__/X11/ <cmdline> -.I /etc/X11/__xconfigdir__ -.I __sysconfdir__/X11/__xconfigdir__ -.fi -.RE -.PP -where -.I <cmdline> -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 -<cmdline> -.IR /etc/X11/ <cmdline> -.IR __sysconfdir__/X11/ <cmdline> -.I /etc/X11/__xconfigdir__ -.I __sysconfdir__/X11/__xconfigdir__ -.fi -.RE -.PP -where -.I <cmdline> -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.

+.SH NAME
+__xconfigfile__ and __xconfigdir__ \- configuration files for
+__xservername__ X server
+.SH INTRODUCTION
+.B __xservername__
+supports several mechanisms for supplying/obtaining configuration and
+run-time parameters: command line options, environment variables, the
+__xconfigfile__ and __xconfigdir__ 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 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/ <cmdline>
+.IR __projectroot__/etc/X11/ <cmdline>
+.IB /etc/X11/ $XORGCONFIG
+.IB __projectroot__/etc/X11/ $XORGCONFIG
+.I /etc/X11/__xconfigfile__
+.I /etc/__xconfigfile__
+.IR __projectroot__/etc/X11/__xconfigfile__. <hostname>
+.I __projectroot__/etc/X11/__xconfigfile__
+.IR __projectroot__/lib/X11/__xconfigfile__. <hostname>
+.I __projectroot__/lib/X11/__xconfigfile__
+.fi
+.RE
+.PP
+where
+.I <cmdline>
+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 <hostname>
+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
+<cmdline>
+.IR /etc/X11/ <cmdline>
+.IR __projectroot__/etc/X11/ <cmdline>
+.B $XORGCONFIG
+.IB /etc/X11/ $XORGCONFIG

+.I __projectroot__/etc/X11/__xconfigfile__
+.IR __projectroot__/lib/X11/__xconfigfile__. <hostname>
+.I __projectroot__/lib/X11/__xconfigfile__
+.fi
+.RE
+.PP
+where
+.I <cmdline>
+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 <hostname>
+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/ <cmdline>
+.IR __sysconfdir__/X11/ <cmdline>
+.I /etc/X11/__xconfigdir__
+.I __sysconfdir__/X11/__xconfigdir__
+.fi
+.RE
+.PP
+where
+.I <cmdline>
+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
+<cmdline>
+.IR /etc/X11/ <cmdline>
+.IR __sysconfdir__/X11/ <cmdline>
+.I /etc/X11/__xconfigdir__
+.I __sysconfdir__/X11/__xconfigdir__
+.fi
+.RE
+.PP
+where
+.I <cmdline>
+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. These are to separate configuration files from
+the vendor or 3rd party packages from those of local administration.
+These files are found in the following directories:
+.PP
+.RS 4
+.nf
+.I /usr/share/X11/__xconfigdir__
+.I __datadir__/X11/__xconfigdir__
+.fi
+.RE
+.PP
+The
+.I __xconfigfile__
+and
+.I __xconfigdir__
+files are composed of a number of sections which may be present in any order,
+or omitted to use default configuration values.
+Each section has the form:
+.PP
+.RS 4
+.nf
+.BI "Section \*q" SectionName \*q
+.RI " " SectionEntry
+ ...
+.B EndSection
+.fi
+.RE
+.PP
+The section names are:
+.PP
+.RS 4
+.nf
+.BR "Files " "File pathnames"
+.BR "ServerFlags " "Server flags"
+.BR "Module " "Dynamic module loading"
+.BR "Extensions " "Extension enabling"
+.BR "InputDevice " "Input device description"

+.BR "Screen " "Screen configuration"
+.BR "ServerLayout " "Overall layout"
+.BR "DRI " "DRI\-specific configuration"
+.BR "Vendor " "Vendor\-specific configuration"
+.fi
+.RE
+.PP
+The following obsolete section names are still recognised for compatibility
+purposes.
+In new config files, the
+.B InputDevice
+section should be used instead.
+.PP
+.RS 4
+.nf
+.BR "Keyboard " "Keyboard configuration"
+.BR "Pointer " "Pointer/mouse configuration"
+.fi
+.RE
+.PP
+The old
+.B XInput
+section is no longer recognised.
+.PP
+The
+.B ServerLayout
+sections are at the highest level.
+They bind together the input and output devices that will be used in a session.
+The input devices are described in the
+.B InputDevice
+sections.
+Output devices usually consist of multiple independent components (e.g.,
+a graphics board and a monitor).
+These multiple components are bound together in the
+.B Screen
+sections, and it is these that are referenced by the
+.B ServerLayout
+section.
+Each
+.B Screen
+section binds together a graphics board and a monitor.
+The graphics boards are described in the
+.B Device
+sections, and the monitors are described in the
+.B Monitor
+sections.
+.PP
+Config file keywords are case\-insensitive, and \(lq_\(rq characters are
+ignored.
+Most strings (including
+.B Option
+names) are also case-insensitive, and insensitive to white space and
+\(lq_\(rq characters.
+.PP
+Each config file entry usually takes up a single line in the file. They
+consist of a keyword, which is possibly followed by one or more arguments,
+with the number and types of the arguments depending on the keyword.
+The argument types are:
+.PP
+.RS 4
+.nf
+.BR "Integer " "an integer number in decimal, hex or octal"
+.BR "Real " "a floating point number"
+.BR "String " "a string enclosed in double quote marks (\*q)"
+.fi
+.RE
+.PP
+Note: hex integer values must be prefixed with \(lq0x\(rq, and octal values
+with \(lq0\(rq.
+.PP
+A special keyword called
+.B Option
+may be used to provide free\-form data to various components of the server.
+The
+.B Option
+keyword takes either one or two string arguments.
+The first is the option name, and the optional second argument is the
+option value.
+Some commonly used option value types include:
+.PP
+.RS 4
+.nf
+.BR "Integer " "an integer number in decimal, hex or octal"
+.BR "Real " "a floating point number"
+.BR "String " "a sequence of characters"
+.BR "Boolean " "a boolean value (see below)"
+.BR "Frequency " "a frequency value (see below)"
+.fi
+.RE
+.PP
+Note that
+.I all
+.B Option
+values, not just strings, must be enclosed in quotes.
+.PP
+Boolean options may optionally have a value specified.
+When no value is specified, the option's value is
+.BR TRUE .
+The following boolean option values are recognised as
+.BR TRUE :
+.PP
+.RS 4
+.BR 1 ,
+.BR on ,
+.BR true ,
+.B yes
+.RE
+.PP
+and the following boolean option values are recognised as
+.BR FALSE :
+.PP
+.RS 4
+.BR 0 ,
+.BR off ,
+.BR false ,
+.B no
+.RE
+.PP
+If an option name is prefixed with
+.RB \*q No \*q,
+then the option value is negated.
+.PP
+Example: the following option entries are equivalent:
+.PP
+.RS 4
+.nf
+.B "Option \*qAccel\*q \*qOff\*q"
+.B "Option \*qNoAccel\*q"
+.B "Option \*qNoAccel\*q \*qOn\*q"
+.B "Option \*qAccel\*q \*qfalse\*q"
+.B "Option \*qAccel\*q \*qno\*q"
+.fi
+.RE
+.PP
+Frequency option values consist of a real number that is optionally
+followed by one of the following frequency units:
+.PP
+.RS 4
+.BR Hz ,
+.BR k ,
+.BR kHz ,
+.BR M ,
+.B MHz
+.RE
+.PP
+When the unit name is omitted, the correct units will be determined from
+the value and the expectations of the appropriate range of the value.
+It is recommended that the units always be specified when using frequency
+option values to avoid any errors in determining the value.
+.SH "FILES SECTION"
+The
+.B Files
+section is used to specify some path names required by the server.
+Some of these paths can also be set from the command line (see
+.BR Xserver (__appmansuffix__)
+and
+.BR __xservername__ (__appmansuffix__)).
+The command line settings override the values specified in the config
+file.
+The
+.B Files
+section is optional, as are all of the entries that may appear in it.
+.PP
+The entries that can appear in this section are:
+.TP 7
+.BI "FontPath \*q" path \*q
+sets the search path for fonts.
+This path is a comma separated list of font path elements which the __xservername__
+server searches for font databases.
+Multiple
+.B FontPath
+entries may be specified, and they will be concatenated to build up the
+fontpath used by the server. Font path elements can be absolute
+directory paths, catalogue directories or a font server identifier. The
+formats of the later two are explained below:
+.PP
+.RS 7
+Catalogue directories:
+.PP
+.RS 4
+Catalogue directories can be specified using the prefix \fBcatalogue:\fR
+before the directory name. The directory can then be populated with
+symlinks pointing to the real font directories, using the following
+syntax in the symlink name:
+.PP
+.RS 4
+.IR <identifier> : [attribute]: pri= <priority>
+.RE
+.PP
+where
+.I <identifier>
+is an alphanumeric identifier,
+.I [attribute]
+is an attribute which will be passed to the underlying FPE and
+.I <priority>
+is a number used to order the fontfile FPEs. Examples:
+.PP

+.RS 4
+.PP
+.IR <trans> / <hostname> : <port\-number>
+.RE
+.PP
+where
+.I <trans>
+is the transport type to use to connect to the font server (e.g.,
+.B unix
+for UNIX\-domain sockets or
+.B tcp
+for a TCP/IP connection),
+.I <hostname>
+is the hostname of the machine running the font server, and
+.I <port\-number>
+is the port number that the font server is listening on (usually 7100).
+.RE
+.PP
+When this entry is not specified in the config file, the server falls back
+to the compiled\-in default font path, which contains the following
+font path elements (which can be set inside a catalogue directory):

+.PP
+.RS 11
+__xkbdir__
+.RE
+.SH "SERVERFLAGS SECTION"
+In addition to options specific to this section (described below), the
+.B ServerFlags
+section is used to specify some global
+__xservername__ server options.
+All of the entries in this section are
+.BR Options ,
+although for compatibility purposes some of the old style entries are
+still recognised.
+Those old style entries are not documented here, and using them is
+discouraged.
+The
+.B ServerFlags
+section is optional, as are the entries that may be specified in it.
+.PP
+.B Options
+specified in this section (with the exception of the
+.B \*qDefaultServerLayout\*q
+.BR Option )
+may be overridden by
+.B Options
+specified in the active
+.B ServerLayout
+section.
+Options with command line equivalents are overridden when their command
+line equivalent is used.
+The options recognised by this section are:
+.TP 7
+.BI "Option \*qDefaultServerLayout\*q \*q" layout\-id \*q
+This specifies the default
+.B ServerLayout
+section to use in the absence of the
+.B \-layout
+command line option.
+.TP 7
+.BI "Option \*qNoTrapSignals\*q \*q" boolean \*q
+This prevents the __xservername__ server from trapping a range of unexpected fatal
+signals and exiting cleanly.
+Instead, the __xservername__ server will die and drop core where the fault occurred.
+The default behaviour is for the __xservername__ server to exit cleanly, but still drop a
+core file.
+In general you never want to use this option unless you are debugging an __xservername__
+server problem and know how to deal with the consequences.
+.TP 7
+.BI "Option \*qUseSIGIO\*q \*q" boolean \*q
+This controls whether the __xservername__ server requests that events from
+input devices be reported via a SIGIO signal handler (also known as SIGPOLL
+on some platforms), or only reported via the standard select(3) loop.
+The default behaviour is platform specific. In general you do not want to
+use this option unless you are debugging the __xservername__ server, or
+working around a specific bug until it is fixed, and understand the
+consequences.
+.TP 7
+.BI "Option \*qDontVTSwitch\*q \*q" boolean \*q
+This disallows the use of the
+.BI Ctrl+Alt+F n
+sequence (where
+.RI F n
+refers to one of the numbered function keys).
+That sequence is normally used to switch to another \*qvirtual terminal\*q
+on operating systems that have this feature.
+When this option is enabled, that key sequence has no special meaning and
+is passed to clients.
+Default: off.
+.TP 7
+.BI "Option \*qDontZap\*q \*q" boolean \*q
+This disallows the use of the
+.B Terminate_Server
+XKB action (usually on Ctrl+Alt+Backspace, depending on XKB options).
+This action is normally used to terminate the __xservername__ server.
+When this option is enabled, the action has no effect.
+Default: off.
+.TP 7
+.BI "Option \*qDontZoom\*q \*q" boolean \*q
+This disallows the use of the
+.B Ctrl+Alt+Keypad\-Plus
+and
+.B Ctrl+Alt+Keypad\-Minus
+sequences.
+These sequences allows you to switch between video modes.
+When this option is enabled, those key sequences have no special meaning
+and are passed to clients.
+Default: off.
+.TP 7
+.BI "Option \*qDisableVidModeExtension\*q \*q" boolean \*q
+This disables the parts of the VidMode extension used by the xvidtune client
+that can be used to change the video modes.
+Default: the VidMode extension is enabled.
+.TP 7
+.BI "Option \*qAllowNonLocalXvidtune\*q \*q" boolean \*q
+This allows the xvidtune client (and other clients that use the VidMode
+extension) to connect from another host.
+Default: off.
+.TP 7
+.BI "Option \*qAllowMouseOpenFail\*q \*q" boolean \*q
+This tells the mousedrv(__drivermansuffix__) and vmmouse(__drivermansuffix__)
+drivers to not report failure if the mouse device can't be opened/initialised.
+It has no effect on the evdev(__drivermansuffix__) or other drivers.
+Default: false.
+.TP 7
+.BI "Option \*qVTSysReq\*q \*q" boolean \*q
+enables the SYSV\-style VT switch sequence for non\-SYSV systems
+which support VT switching.
+This sequence is
+.B Alt\-SysRq
+followed by a function key
+.RB ( Fn ).
+This prevents the __xservername__ server trapping the
+keys used for the default VT switch sequence, which means that clients can
+access them.
+Default: off.
+.TP 7
+.BI "Option \*qBlankTime\*q \*q" time \*q
+sets the inactivity timeout for the
+.B blank
+phase of the screensaver.
+.I time
+is in minutes.
+This is equivalent to the __xservername__ server's
+.B \-s
+flag, and the value can be changed at run\-time with
+.BR xset(__appmansuffix__).
+Default: 10 minutes.
+.TP 7
+.BI "Option \*qStandbyTime\*q \*q" time \*q
+sets the inactivity timeout for the
+.B standby
+phase of DPMS mode.
+.I time
+is in minutes, and the value can be changed at run\-time with
+.BR xset(__appmansuffix__).
+Default: 10 minutes.
+This is only suitable for VESA DPMS compatible monitors, and may not be
+supported by all video drivers.
+It is only enabled for screens that have the
+.B \*qDPMS\*q
+option set (see the MONITOR section below).
+.TP 7
+.BI "Option \*qSuspendTime\*q \*q" time \*q
+sets the inactivity timeout for the
+.B suspend
+phase of DPMS mode.
+.I time
+is in minutes, and the value can be changed at run\-time with
+.BR xset(__appmansuffix__).
+Default: 10 minutes.
+This is only suitable for VESA DPMS compatible monitors, and may not be
+supported by all video drivers.
+It is only enabled for screens that have the
+.B \*qDPMS\*q
+option set (see the MONITOR section below).
+.TP 7
+.BI "Option \*qOffTime\*q \*q" time \*q
+sets the inactivity timeout for the
+.B off
+phase of DPMS mode.
+.I time
+is in minutes, and the value can be changed at run\-time with
+.BR xset(__appmansuffix__).
+Default: 10 minutes.
+This is only suitable for VESA DPMS compatible monitors, and may not be
+supported by all video drivers.
+It is only enabled for screens that have the
+.B \*qDPMS\*q
+option set (see the MONITOR section below).
+.TP 7
+.BI "Option \*qPixmap\*q \*q" bpp \*q
+This sets the pixmap format to use for depth 24.
+Allowed values for
+.I bpp
+are 24 and 32.
+Default: 32 unless driver constraints don't allow this (which is rare).
+Note: some clients don't behave well when this value is set to 24.
+.TP 7
+.BI "Option \*qPC98\*q \*q" boolean \*q
+Specify that the machine is a Japanese PC\-98 machine.
+This should not be enabled for anything other than the Japanese\-specific
+PC\-98 architecture.
+Default: auto\-detected.
+.TP 7
+.BI "Option \*qNoPM\*q \*q" boolean \*q
+Disables something to do with power management events.
+Default: PM enabled on platforms that support it.
+.TP 7
+.BI "Option \*qXinerama\*q \*q" boolean \*q
+enable or disable XINERAMA extension.
+Default is disabled.
+.TP 7

+.SH "MODULE SECTION"
+The
+.B Module
+section is used to specify which __xservername__ server modules should be loaded.
+This section is ignored when the __xservername__ server is built in static form.
+The type of modules normally loaded in this section are __xservername__ server
+extension modules.
+Most other module types are loaded automatically when they are needed via
+other mechanisms.
+The
+.B Module
+section is optional, as are all of the entries that may be specified in
+it.
+.PP
+Entries in this section may be in two forms.
+The first and most commonly used form is an entry that uses the
+.B Load
+keyword, as described here:
+.TP 7
+.BI "Load \*q" modulename \*q
+This instructs the server to load the module called
+.IR modulename .
+The module name given should be the module's standard name, not the
+module file name.
+The standard name is case\-sensitive, and does not include the \(lqlib\(rq
+prefix, or the \(lq.a\(rq, \(lq.o\(rq, or \(lq.so\(rq suffixes.
+.PP
+.RS 7
+Example: the DRI extension module can be loaded with the following entry:
+.PP
+.RS 4
+.B "Load \*qdri\*q"
+.RE
+.RE
+.TP 7
+.BI "Disable \*q" modulename \*q
+This instructs the server to not load the module called
+.IR modulename .
+Some modules are loaded by default in the server, and this overrides that
+default. If a
+.B Load
+instruction is given for the same module, it overrides the
+.B Disable
+instruction and the module is loaded. The module name given should be the
+module's standard name, not the module file name. As with the
+.B Load
+instruction, the standard name is case-sensitive, and does not include the
+"lib" prefix, or the ".a", ".o", or ".so" suffixes.
+.PP
+The second form of entry is a
+.BR SubSection,
+with the subsection name being the module name, and the contents of the
+.B SubSection
+being
+.B Options
+that are passed to the module when it is loaded.
+.PP
+Example: the extmod module (which contains a miscellaneous group of
+server extensions) can be loaded, with the XFree86\-DGA extension
+disabled by using the following entry:
+.PP
+.RS 4
+.nf
+.B "SubSection \*qextmod\*q"
+.B " Option \*qomit XFree86\-DGA\*q"
+.B EndSubSection
+.fi
+.RE
+.PP
+Modules are searched for in each directory specified in the
+.B ModulePath
+search path, and in the drivers, extensions, input, internal, and
+multimedia subdirectories of each of those directories.
+In addition to this, operating system specific subdirectories of all
+the above are searched first if they exist.
+.PP
+To see what extension modules are available, check the extensions
+subdirectory under:
+.PP
+.RS 4
+.nf
+__modulepath__
+.fi
+.RE
+.PP
+The \(lqextmod\(rq, \(lqdbe\(rq, \(lqdri\(rq, \(lqdri2\(rq, \(lqglx\(rq,
+and \(lqrecord\(rq extension modules are loaded automatically, if they
+are present, unless disabled with \*qDisable\*q entries.
+It is recommended
+that at very least the \(lqextmod\(rq extension module be loaded.
+If it isn't, some commonly used server extensions (like the SHAPE
+extension) will not be available.
+.SH "EXTENSIONS SECTION"
+The
+.B Extensions
+section is used to specify which X11 protocol extensions should be enabled
+or disabled.
+The
+.B Extensions
+section is optional, as are all of the entries that may be specified in
+it.
+.PP
+Entries in this section are listed as Option statements with the name of
+the extension as the first argument, and a boolean value as the second.
+The extension name is case\-sensitive, and matches the form shown in the output
+of \*qXorg -extension ?\*q.
+.PP
+.RS 7
+Example: the MIT-SHM extension can be disabled with the following entry:
+.PP
+.RS 4
+.nf

+.RE
+.RE
+.SH "INPUTDEVICE SECTION"
+The config file may have multiple
+.B InputDevice
+sections.
+Recent X servers employ HAL or udev backends for input device enumeration
+and input hotplugging. It is usually not
+necessary to provide
+.B InputDevice
+sections in the xorg.conf if hotplugging is in use. If hotplugging is
+enabled,
+.B InputDevice
+sections using the
+.B mouse, kbd
+and
+.B vmmouse
+driver will be ignored.
+.PP
+If hotplugging is disabled, there will normally
+be at least two: one for the core (primary) keyboard
+and one for the core pointer.
+If either of these two is missing, a default configuration for the missing
+ones will be used. In the absence of an explicitly specified core input
+device, the first
+.B InputDevice
+marked as
+.B CorePointer
+(or
+.BR CoreKeyboard )
+is used.
+If there is no match there, the first
+.B InputDevice

+the most important acceleration options are discussed here.
+.TP 7
+.BI "Option \*qAccelerationProfile\*q \*q" integer \*q

+factor is a rational which, together with threshold, can be used to tweak
+profiles to suit the users needs. The
+.B simple
+and
+.B limited
+profiles use it directly (i.e. they accelerate by the factor), for other
+profiles it should hold that a higher acceleration factor leads to a faster
+pointer. Typically, 1 is unaccelerated and values up to 5 are sensible.

+override those given in the
+.B ServerFlags
+section.
+.PP
+The entries that may be used in this section are described here.
+.TP 7
+.BI "Screen " "screen\-num" " \*qscreen\-id\*q " "position\-information"
+One of these entries must be given for each screen being used in
+a session.
+The
+.I screen\-id
+field is mandatory, and specifies the
+.B Screen
+section being referenced.
+The
+.I screen\-num
+field is optional, and may be used to specify the screen number
+in multi\-head configurations.
+When this field is omitted, the screens will be numbered in the order that
+they are listed in.
+The numbering starts from 0, and must be consecutive.
+The
+.I position\-information
+field describes the way multiple screens are positioned.
+There are a number of different ways that this information can be provided:
+.RS 7
+.TP 4
+.I "x y"
+.TP 4
+.BI "Absolute " "x y"
+These both specify that the upper left corner's coordinates are
+.RI ( x , y ).
+The
+.B Absolute
+keyword is optional.
+Some older versions of XFree86 (4.2 and earlier) don't recognise the
+.B Absolute
+keyword, so it's safest to just specify the coordinates without it.
+.TP 4
+.BI "RightOf \*q" screen\-id \*q
+.TP 4
+.BI "LeftOf \*q" screen\-id \*q
+.TP 4
+.BI "Above \*q" screen\-id \*q
+.TP 4
+.BI "Below \*q" screen\-id \*q
+.TP 4
+.BI "Relative \*q" screen\-id \*q " x y"
+These give the screen's location relative to another screen.
+The first four position the screen immediately to the right, left, above or
+below the other screen.
+When positioning to the right or left, the top edges are aligned.
+When positioning above or below, the left edges are aligned.
+The
+.B Relative
+form specifies the offset of the screen's origin (upper left corner)
+relative to the origin of another screen.
+.RE
+.TP 7
+.BI "InputDevice \*q" idev\-id "\*q \*q" option \*q " ..."
+One of these entries should be given for each input device being used in
+a session.
+Normally at least two are required, one each for the core pointer and
+keyboard devices.
+If either of those is missing, suitable
+.B InputDevice
+entries are searched for using the method described above in the
+.B INPUTDEVICE
+section. The
+.I idev\-id
+field is mandatory, and specifies the name of the
+.B InputDevice
+section being referenced.
+Multiple
+.I option
+fields may be specified, each in double quotes.
+The options permitted here are any that may also be given in the
+.B InputDevice
+sections.
+Normally only session\-specific input device options would be used here.
+The most commonly used options are:
+.PP
+.RS 11
+.nf
+.B \*qCorePointer\*q
+.B \*qCoreKeyboard\*q
+.B \*qSendCoreEvents\*q
+.fi
+.RE
+.PP
+.RS 7
+and the first two should normally be used to indicate the core pointer
+and core keyboard devices respectively.
+.RE
+.TP 7
+.B Options
+In addition to the following, any option permitted in the
+.B ServerFlags
+section may also be specified here.
+When the same option appears in both places, the value given here overrides
+the one given in the
+.B ServerFlags
+section.
+.TP 7
+.BI "Option \*qIsolateDevice\*q \*q" bus\-id \*q
+Restrict device resets to the specified
+.IR bus\-id .
+See the
+.B BusID
+option (described in
+.BR "DEVICE SECTION" ,
+above) for the format of the
+.I bus\-id
+parameter.
+This option overrides
+.BR SingleCard ,
+if specified.
+At present, only PCI devices can be isolated in this manner.
+.TP 7
+.BI "Option \*qSingleCard\*q \*q" boolean \*q
+As
+.BR IsolateDevice ,
+except that the bus ID of the first device in the layout is used.
+.PP
+Here is an example of a
+.B ServerLayout
+section for a dual headed configuration with two mice:
+.PP
+.RS 4
+.nf
+.B "Section \*qServerLayout\*q"
+.B " Identifier \*qLayout 1\*q"
+.B " Screen \*qMGA 1\*q"

+.RE
+.SH "DRI SECTION"
+This optional section is used to provide some information for the
+Direct Rendering Infrastructure.
+Details about the format of this section can be found on-line at
+.IR <http://dri.freedesktop.org/> .
+.SH "VENDOR SECTION"
+The optional
+.B Vendor
+section may be used to provide vendor\-specific configuration information.
+Multiple
+.B Vendor
+sections may be present, and they may contain an
+.B Identifier
+entry and multiple
+.B Option
+flags.
