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

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

sections, and the monitors are described in the
|
|
.B Monitor
|
|
sections.

Config file keywords are case-insensitive, and "_" characters are
|
|
ignored. Most strings (including

|
.B Option
|
|
names) are also case-insensitive, and insensitive to white space and
|
|
"_" characters.
|

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:

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:

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 ,

.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 Xserver(__appmansuffix__)
|
|
and __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 may be either absolute
|
|
directory paths, or a font server identifier. Font server identifiers
|
|
have the form:
|
|
.PP
|
|
.RS 11
|
|
.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>
|

.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 \*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 Ctrl+Alt+Backspace
|
|
sequence. That sequence is normally used to terminate the __xservername__ server.
|
|
When this option is enabled, that key sequence has no special meaning
|
|
and is passed to clients. 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 \*qDisableModInDev\*q \*q" boolean \*q
|
|
This disables the parts of the __xservername__-Misc extension that can be used to

modify the input device settings dynamically. Default: that functionality
|
|
is enabled.
|
|
.TP 7
|
|
.BI "Option \*qAllowNonLocalModInDev\*q \*q" boolean \*q
|
|
This allows a client to connect from another host and change keyboard
|
|
and mouse settings in the running server. Default: off.
|
|
.TP 7
|
|
.BI "Option \*qAllowMouseOpenFail\*q \*q" boolean \*q
|
|
This allows the server to start up even if the mouse device can't be
|
|
opened/initialised. Default: false.
|

.TP 7
|
|
.BI "Option \*qVTInit\*q \*q" command \*q
|
|
Runs
|
|
.I command
|
|
after the VT used by the server has been opened.
|
|
The command string is passed to "/bin/sh -c", and is run with the
|
|
real user's id with stdin and stdout set to the VT. The purpose
|
|
of this option is to allow system dependent VT initialisation
|
|
commands to be run. This option should rarely be needed. Default: not set.
|
|
.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 \*qXkbDisable\*q \*q" boolean \*q

.BR Ctrl+Alt+Backspace ).
|
|
Normally the XKEYBOARD extension keymaps will provide mappings for each

can be
|
|
.BR Always ,

|
|
Default: Use the builtin handler only if needed. The server will scan
|
|
the keymap for a mapping to the
|
|
.B Terminate
|
|
action and, if found, use XKEYBOARD for processing actions, otherwise
|
|
the builtin handler will be used.
|
|
.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 "lib" prefix, or the ".a", ".o", or ".so" suffixes.
|
|
.PP
|
|
.RS 7
|
|
Example: the Type 1 font rasteriser can be loaded with the following entry:
|
|
.PP
|
|
.RS 4
|
|
.B "Load \*qtype1\*q"
|
|
.RE
|
|
.RE
|
|
.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 __xservername__-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 "bitmap" font modules is loaded automatically. It is recommended
|
|
that at very least the "extmod" 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.
|
|
.PP
|
|
.B InputDevice
|
|
sections have the following format:
|
|
.PP
|
|
.RS 4
|
|
.nf
|
|
.B "Section \*qInputDevice\*q"
|
|
.BI " Identifier \*q" name \*q

.PP
|
|
The
|
|
.B Identifier
|
|
and
|
|
.B Driver
|
|
entries are required in all
|
|
.B InputDevice
|
|
sections. All other entries are optional.
|
|
.PP
|
|
The
|
|
.B Identifier
|
|
entry specifies the unique name for this input device. The
|
|
.B Driver
|
|
entry specifies the name of the driver to use for this input device.
|
|
When using the loadable server, the input driver module
|
|
.RI \*q inputdriver \*q
|
|
will be loaded for each active
|
|
.B InputDevice
|
|
section. An
|
|
.B InputDevice
|
|
section is considered active if it is referenced by an active
|
|
.B ServerLayout
|
|
section, if it is referenced by the
|
|
.B \-keyboard
|
|
or
|
|
.B \-pointer
|
|
command line options, or if it is selected implicitly as the core pointer
|
|
or keyboard device in the absence of such explicit references.
|
|
The most commonly used input drivers are "keyboard" and "mouse".
|
|
.PP
|
|
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
|
|
that uses the "mouse" (or "keyboard" or "kbd") driver is used. The final
|
|
fallback is to use built-in default configurations.
|
|
.PP
|
|
.B InputDevice
|
|
sections recognise some driver-independent
|
|
.BR Options ,
|
|
which are described here. See the individual input driver manual pages
|
|
for a description of the device-specific options.
|
|
.TP 7
|
|
.BI "Option \*qCorePointer\*q"
|
|
When this is set, the input device is installed as the core (primary)
|
|
pointer device. There must be exactly one core pointer. If this option
|
|
is not set here, or in the
|
|
.B ServerLayout
|
|
section, or from the
|
|
.B \-pointer
|
|
command line option, then the first input device that is capable of
|
|
being used as a core pointer will be selected as the core pointer.
|
|
This option is implicitly set when the obsolete
|
|
.B Pointer
|
|
section is used.
|
|
.TP 7
|
|
.BI "Option \*qCoreKeyboard\*q"
|
|
When this is set, the input device is to be installed as the core
|
|
(primary) keyboard device. There must be exactly one core keyboard. If
|
|
this option is not set here, in the
|
|
.B ServerLayout
|
|
section, or from the
|
|
.B \-keyboard
|
|
command line option, then the first input device that is capable of
|
|
being used as a core keyboard will be selected as the core keyboard.
|
|
This option is implicitly set when the obsolete
|
|
.B Keyboard
|
|
section is used.
|
|
.TP 7
|
|
.BI "Option \*qAlwaysCore\*q \*q" boolean \*q
|
|
.TP 7
|
|
.BI "Option \*qSendCoreEvents\*q \*q" boolean \*q
|
|
Both of these options are equivalent, and when enabled cause the
|
|
input device to always report core events. This can be used, for
|
|
example, to allow an additional pointer device to generate core
|
|
pointer events (like moving the cursor, etc).
|
|
.TP 4
|
|
.BI "Option \*qHistorySize\*q \*q" number \*q

|
.B Driver
|
|
entries are required in all
|
|
.B Device
|
|
sections. All other entries are optional.
|
|
.PP
|
|
The
|
|
.B Identifier
|
|
entry specifies the unique name for this graphics device. The
|
|
.B Driver
|
|
entry specifies the name of the driver to use for this graphics device.
|
|
When using the loadable server, the driver module
|
|
.RI \*q driver \*q
|
|
will be loaded for each active
|
|
.B Device
|
|
section. A
|

section is considered active if it is referenced by an active
|
|
.B Screen

section.
|
|
.PP
|
|
.B Device
|
|
sections recognise some driver-independent entries and
|
|
.BR Options ,
|
|
which are described here. Not all drivers make use of these
|
|
driver-independent entries, and many of those that do don't require them
|
|
to be specified because the information is auto-detected. See the
|
|
individual graphics driver manual pages for further information about
|
|
this, and for a description of the device-specific options.
|
|
Note that most of the
|
|
.B Options
|
|
listed here (but not the other entries) may be specified in the
|
|
.B Screen
|
|
section instead of here in the
|
|
.B Device
|
|
section.
|
|
.TP 7
|
|
.BI "BusID \*q" bus-id \*q
|
|
This specifies the bus location of the graphics card. For PCI/AGP cards,
|
|
the
|
|
.I bus-id
|
|
string has the form
|
|
.BI PCI: bus : device : function
|
|
(e.g., "PCI:1:0:0" might be appropriate for an AGP card).
|
|
This field is usually optional in single-head configurations when using
|
|
the primary graphics card. In multi-head configurations, or when using
|
|
a secondary graphics card in a single-head configuration, this entry is
|
|
mandatory. Its main purpose is to make an unambiguous connection between
|
|
the device section and the hardware it is representing. This information
|
|
can usually be found by running the __xservername__ server with the
|
|
.B \-scanpci
|
|
command line option.
|
|
.TP 7
|
|
.BI "Screen " number
|
|
This option is mandatory for cards where a single PCI entity can drive more
|
|
than one display (i.e., multiple CRTCs sharing a single graphics accelerator
|
|
and video memory). One
|
|
.B Device
|
|
section is required for each head, and this
|
|
parameter determines which head each of the
|
|
.B Device
|
|
sections applies to. The legal values of
|
|
.I number
|
|
range from 0 to one less than the total number of heads per entity.
|
|
Most drivers require that the primary screen (0) be present.
|
|
.TP 7
|
|
.BI "Chipset \*q" chipset \*q
|
|
This usually optional entry specifies the chipset used on the graphics
|
|
board. In most cases this entry is not required because the drivers
|
|
will probe the hardware to determine the chipset type. Don't
|
|
specify it unless the driver-specific documentation recommends that you
|
|
do.
|
|
.TP 7
|
|
.BI "Ramdac \*q" ramdac-type \*q
|
|
This optional entry specifies the type of RAMDAC used on the graphics
|
|
board. This is only used by a few of the drivers, and in most cases it
|
|
is not required because the drivers will probe the hardware to determine
|
|
the RAMDAC type where possible. Don't specify it unless the
|
|
driver-specific documentation recommends that you do.
|
|
.TP 7
|
|
.BI "DacSpeed " speed
|
|
.TP 7
|
|
.BI "DacSpeed " "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 give, 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 clocks. Don't specify this entry unless
|
|
the driver-specific documentation explicitly recommends that you do.
|
|
.TP
|
|
.BI "ClockChip \*q" clockchip-type \*q
|
|
This optional entry is used to specify the 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

|
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 chip type.
|
|
For PCI cards, it is usually the device ID. This can be used to override
|
|
the auto-detection, but that should only be done when the driver-specific
|
|
documentation recommends it.
|
|
.TP 7
|
|
.BI "ChipRev " "rev"
|
|
This optional entry specifies the chip revision number. This can be

|
the driver-specific documentation recommends it.
|
|
.TP 7
|
|
.BI "TextClockFreq " "freq"

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
|
|
section provides information about the specifications of the monitor,
|
|
monitor-specific
|
|
.BR Options ,
|
|
and information about the video modes to use with the monitor. Specifying
|
|
video modes is optional because the server now has a built-in list of
|
|
VESA standard modes. When modes are specified explicitly in the
|
|
.B Monitor
|
|
section (with the
|
|
.BR Modes ,
|
|
.BR ModeLine ,
|
|
or
|
|
.B UseModes
|
|
keywords), built-in modes with the same names are not included. Built-in
|
|
modes with different names are, however, still implicitly included.
|

The entries that may be used in
|
|
.B Monitor
|
|
sections are described below.
|
|
.TP 7
|
|
.BI "VendorName \*q" vendor \*q
|
|
This optional entry specifies the monitor's manufacturer.
|
|
.TP 7
|
|
.BI "ModelName \*q" model \*q
|
|
This optional entry specifies the monitor's model.
|
|
.TP 7
|
|
.BI "HorizSync " "horizsync-range"
|
|
gives the range(s) of horizontal sync frequencies supported by the
|
|
monitor.
|
|
.I horizsync-range
|
|
may be a comma separated list of either discrete values or ranges of
|
|
values. A range of values is two values separated by a dash. By default
|
|
the values are in units of kHz. They may be specified in MHz or Hz if
|
|
.B MHz
|
|
or
|
|
.B Hz
|
|
is added to the end of the line. The data given here is used by the
|
|
__xservername__ server to determine if video modes are within the specifications
|
|
of the monitor. This information should be available in the monitor's
|
|
handbook. If this entry is omitted, a default range of 28\-33kHz is
|
|
used.
|
|
.TP 7
|
|
.BI "VertRefresh " "vertrefresh-range"
|
|
gives the range(s) of vertical refresh frequencies supported by the
|
|
monitor.
|
|
.I vertrefresh-range
|
|
may be a comma separated list of either discrete values or ranges of
|
|
values. A range of values is two values separated by a dash. By default
|
|
the values are in units of Hz. They may be specified in MHz or kHz if
|
|
.B MHz
|

handbook. If this entry is omitted, a default range of 43-72Hz is used.
|
|
.TP 7
|
|
.BI "DisplaySize " "width height"
|
|
This optional entry gives the width and height, in millimetres, of the
|
|
picture area of the monitor. If given this is used to calculate the
|
|
horizontal and vertical pitch (DPI) of the screen.
|
|
.TP 7
|
|
.BI "Gamma " "gamma-value"
|
|
.TP 7
|
|
.BI "Gamma " "red-gamma green-gamma blue-gamma"
|
|
This is an optional entry that can be used to specify the gamma correction
|
|
for the monitor. It may be specified as either a single value or as
|
|
three separate RGB values. The values should be in the range 0.1 to
|
|
10.0, and the default is 1.0. Not all drivers are capable of using this
|
|
information.
|
|
.TP 7
|
|
.BI "UseModes \*q" modesection-id \*q
|
|
Include the set of modes listed in the
|
|
.B Modes
|
|
section called
|
|
.IR modesection-id.
|
|
This make all of the modes defined in that section available for use by
|
|
this monitor.
|
|
.TP 7
|
|
.BI "Mode \*q" name \*q
|
|
This is an optional multi-line entry that can be used to provide
|
|
definitions for video modes for the monitor. In most cases this isn't
|
|
necessary because the built-in set of VESA standard modes will be
|
|
sufficient. The
|
|
.B Mode
|
|
keyword indicates the start of a multi-line video mode description.
|
|
The mode description is terminated with the
|
|
.B EndMode
|
|
keyword. The mode description consists of the following entries:
|
|
.RS 7
|
|
.TP 4
|
|
.BI "DotClock " clock
|
|
is the dot (pixel) clock rate to be used for the mode.
|
|
.TP 4
|
|
.BI "HTimings " "hdisp hsyncstart hsyncend htotal"
|
|
specifies the horizontal timings for the mode.
|
|
.TP 4
|
|
.BI "VTimings " "vdisp vsyncstart vsyncend vtotal"
|
|
specifies the vertical timings for the mode.
|
|
.TP 4
|
|
.BI "Flags \*q" flag \*q " ..."
|
|
specifies an optional set of mode flags, each of which is a separate
|
|
string in double quotes.
|
|
.B \*qInterlace\*q
|
|
indicates that the mode is interlaced.
|
|
.B \*qDoubleScan\*q
|
|
indicates a mode where each scanline is doubled.
|
|
.B \*q+HSync\*q
|
|
and
|
|
.B \*q\-HSync\*q
|
|
can be used to select the polarity of the HSync signal.
|
|
.B \*q+VSync\*q
|
|
and
|
|
.B \*q\-VSync\*q
|
|
can be used to select the polarity of the VSync signal.
|
|
.B \*qComposite\*q
|
|
can be used to specify composite sync on hardware where this is supported.
|
|
Additionally, on some hardware,
|
|
.B \*q+CSync\*q
|
|
and
|
|
.B \*q\-CSync\*q
|
|
may be used to select the composite sync polarity.
|
|
.TP 4
|
|
.BI "HSkew " hskew
|
|
specifies the number of pixels (towards the right edge of the screen)
|
|
by which the display enable signal is to be skewed. Not all drivers
|
|
use this information. This option might become necessary to override
|
|
the default value supplied by the server (if any). "Roving" horizontal
|
|
lines indicate this value needs to be increased. If the last few pixels
|
|
on a scan line appear on the left of the screen, this value should be
|
|
decreased.
|
|
.TP 4
|
|
.BI "VScan " vscan
|
|
specifies the number of times each scanline is painted on the screen.
|
|
Not all drivers use this information. Values less than 1 are treated
|
|
as 1, which is the default. Generally, the
|
|
.B \*qDoubleScan\*q
|
|
.B Flag
|
|
mentioned above doubles this value.

is in four sections, the first three of which are mandatory. The first
|
|
is the dot (pixel) clock. This is a single number specifying the pixel
|
|
clock rate for the mode in MHz. The second section is a list of four
|
|
numbers specifying the horizontal timings. These numbers are the
|
|
.IR hdisp ,
|
|
.IR hsyncstart ,
|
|
.IR hsyncend ,
|
|
and
|
|
.I htotal

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. Most hardware that uses 32 bits per pixel only uses 24 of them
|
|
to hold the colour information, which means that the colour depth is
|
|
24, not 32.
|
|
.TP 7
|
|
.BI "FbBpp " bpp
|
|
This entry specifies the framebuffer format this
|
|
.B Display
|
|
subsection is to be used for. This entry is only needed when providing
|
|
depth 24 configurations that allow a choice between a 24 bpp packed
|
|
framebuffer format and a 32bpp sparse framebuffer format. In most cases
|
|
this entry should not be used.
|
|
.TP 7
|
|
.BI "Weight " "red-weight green-weight blue-weight"
|
|
This optional entry specifies the relative RGB weighting to be used
|
|
for a screen is being used at depth 16 for drivers that allow multiple
|
|
formats. This may also be specified from the command line with the
|
|
.B \-weight
|
|
option (see __xservername__(__appmansuffix__)).
|
|
.TP 7
|
|
.BI "Virtual " "xdim ydim"
|
|
This optional entry specifies the virtual screen resolution to be used.
|
|
.I xdim
|
|
must be a multiple of either 8 or 16 for most drivers, and a multiple
|
|
of 32 when running in monochrome mode. The given value will be rounded
|
|
down if this is not the case. Video modes which are too large for the
|
|
specified virtual size will be rejected. If this entry is not present,
|
|
the virtual screen resolution will be set to accommodate all the valid
|
|
video modes given in the
|
|
.B Modes
|
|
entry. Some drivers/hardware combinations do not support virtual screens.
|
|
Refer to the appropriate driver-specific documentation for details.
|
|
.TP 7
|
|
.BI "ViewPort " "x0 y0"
|
|
This optional entry sets the upper left corner of the initial display.
|
|
This is only relevant when the virtual screen resolution is different
|
|
from the resolution of the initial video mode. If this entry is not
|
|
given, then the initial display will be centered in the virtual display
|
|
area.
|
|
.TP 7
|
|
.BI "Modes \*q" mode-name \*q " ..."
|
|
This optional entry specifies the list of video modes to use. Each
|
|
.I mode-name
|
|
specified must be in double quotes. They must correspond to those
|
|
specified or referenced in the appropriate
|
|
.B Monitor
|
|
section (including implicitly referenced built-in VESA standard modes).
|
|
The server will delete modes from this list which don't satisfy various
|
|
requirements. The first valid mode in this list will be the default
|
|
display mode for startup. The list of valid modes is converted internally
|
|
into a circular list. It is possible to switch to the next mode with
|
|
.B Ctrl+Alt+Keypad-Plus
|
|
and to the previous mode with
|
|
.BR Ctrl+Alt+Keypad-Minus .
|
|
When this entry is omitted, the valid modes referenced by the appropriate
|
|
.B Monitor
|
|
section will be used. If the
|
|
.B Monitor
|
|
section contains no modes, then the selection will be taken from the
|
|
built-in VESA standard modes.
|

driver-independent options. The former are described in the
|

driver-specific documentation. Some of the latter are described above
|
|
in the section about the
|
|
.B Screen
|
|
section, and they may also be included here.
|
|
.SH SERVERLAYOUT SECTION
|
|
The config file may have multiple
|
|
.B ServerLayout
|
|
sections.
|
|
A "server layout" represents the binding of one or more screens
|
|
.RB ( Screen
|
|
sections) and one or more input devices
|
|
.RB ( InputDevice
|
|
sections) to form a complete configuration. In multi-head configurations,
|
|
it also specifies the relative layout of the heads. A
|
|
.B ServerLayout
|
|
section is considered "active" if it is referenced by the
|
|
.B \-layout
|
|
command line option or by an
|
|
.B "Option \*qDefaultServerLayout\*q"
|
|
entry in the
|
|
.B ServerFlags
|
|
section (the former takes precedence over the latter). If those options are
|
|
not used, the first
|
|
.B ServerLayout
|
|
section found in the config file is considered the active one. If no
|
|
.B ServerLayout
|
|
sections are present, the single active screen and two active (core)
|
|
input devices are selected as described in the relevant sections above.
|
|
.PP
|
|
.B ServerLayout
|
|
sections have the following format:
|

|
|
.B Identifier
|
|
entry and at least one
|
|
.B Screen
|
|
entry.
|
|
.PP
|
|
The
|
|
.B Identifier
|
|
entry specifies the unique name for this server layout. The
|
|
.B ServerLayout
|

section provides information specific to the whole session, including
|
|
session-specific
|
|
.BR Options .
|

|
|
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 __xservername__ (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
|

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
|
|
