| .SH NAME
 | |
| __xconfigfile__ \- configuration File 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__ configuration file, 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__
 | |
| for its initial setup.
 | |
| This configuration file is searched for in the following places when the
 | |
| server is started as a normal user:

| line equivalent is used.
 | |
| The options recognised by this section are:

| .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 \*qDontVTSwitch\*q  \*q" boolean \*q
 | |
| This disallows the use of the

| 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

| sequence.
 | |
| That sequence is normally used to terminate the __xservername__ server.
 | |
| When this option is enabled (as per default), that key sequence has no

| special meaning.
 | |
| Default: on.
 | |
| .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
 | |

| Default: the VidMode extension is enabled.
 | |

 | |
| Default: off.
 | |
| .TP 7
 | |
| .BI "Option \*qAllowMouseOpenFail\*q  \*q" boolean \*q

| .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 types of modules normally loaded in this section are __xservername__ server
 | |
| extension modules, and font rasteriser 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 FreeType font rasteriser can be loaded with the following entry:
 | |
| .PP
 | |
| .RS 4
 | |
| .B "Load \*qfreetype\*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, input, extensions, fonts, and
 | |
| internal 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 font and extension modules are available, check the contents
 | |
| of the following directories:
 | |
| .PP
 | |
| .RS 4
 | |
| .nf
 | |
| __projectroot__/lib/modules/fonts
 | |
| __projectroot__/lib/modules/extensions
 | |
| .fi
 | |
| .RE
 | |
| .PP
 | |
| The \(lqextmod\(rq, \(lqdbe\(rq, \(lqglx\(rq, and \(lqdri\(rq extension
 | |
| modules are loaded automatically, 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 "INPUTDEVICE SECTION"
 | |
| The config file may have multiple
 | |
| .B InputDevice
 | |
| sections.
 | |
| There will normally be at least two: one for the core (primary) keyboard,
 | |
| and one of the core pointer.

| If either of these two is missing, a default configuration for the missing
 | |
| ones will be used.
 | |
| Currently the default configuration may not work as expected on all platforms.

 | |
| The only mandatory entry in a

| .B Monitor
 | |
| section is the
 | |
| .B Identifier
 | |
| entry.
 | |
| .PP
 | |
| The
 | |
| .B Identifier
 | |
| entry specifies the unique name for this monitor.
 | |
| The
 | |
| .B Monitor
 | |

| monitor, monitor-specific
 | |
| .BR Options ,
 | |
| and information about the video modes to use with the monitor.
 | |
| .PP
 | |
| With RandR 1.2-enabled drivers, monitor sections may be tied to specific
 | |
| outputs of the video card.  Using the name of the output defined by the video
 | |
| driver plus the identifier of a monitor section, one associates a monitor
 | |
| section with an output by adding an option to the Device section in the
 | |
| following format:
 | |
| 
 | |
| .B Option \*qMonitor-outputname\*q \*qmonitorsection\*q
 | |
| 
 | |
| (for example, 
 | |
| .B Option \*qMonitor-VGA\*q \*qVGA monitor\*q
 | |
| for a VGA output)
 | |

 | |
| In the absence of specific association of monitor sections to outputs, if a
 | |
| monitor section is present the server will associate it with an output to
 | |
| preserve compatibility for previous single-head configurations.
 | |
| .PP
 | |
| Specifying video modes is optional because the server will use the DDC or other
 | |
| information provided by the monitor to automatically configure the list of
 | |
| modes available.
 | |
| When modes are specified explicitly in the
 | |
| .B Monitor
 | |
| section (with the

| .BR Modes ,
 | |
| .BR ModeLine ,
 | |
| or
 | |
| .B UseModes

| Most drivers support 8, 15, 16 and 24.
 | |
| Some also support 1 and/or 4, and some may support other values (like 30).
 | |
| Note:
 | |
| .I depth
 | |
| means the number of bits in a pixel that are actually used to determine

| the pixel colour.
 | |
| 32 is not a valid
 | |
| .I depth
 | |
| value.
