.SH INTRODUCTION
|
|
.B Xorg
|
|
supports several mechanisms for supplying/obtaining configuration and
|
|
run-time parameters: command line options, environment variables, the
|
|
xorg.conf 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
|
|
Xorg(__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 Xorg
|
|
uses a configuration file called
|
|
.I xorg.conf
|
|
and files ending in the suffix
|
|
.I .conf
|
|
from the directory
|
|
.I __xconfigdir__
|
|
for its initial setup.
|
|
The
|
|
.I xorg.conf
|
|
configuration file is searched for in the following places when the
|
|
server is started as a normal user:

may be overridden by

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

|
|
.B \-layout
|
|
command line option.
|
|
.TP 7
|
|
.BI "Option \*qNoTrapSignals\*q \*q" boolean \*q
|
|
This prevents the Xorg server from trapping a range of unexpected fatal
|
|
signals and exiting cleanly.
|
|
Instead, the Xorg server will die and drop core where the fault occurred.
|
|
The default behaviour is for the Xorg server to exit cleanly, but still drop a
|
|
core file.
|
|
In general you never want to use this option unless you are debugging an Xorg
|
|
server problem and know how to deal with the consequences.
|
|
.TP 7
|
|
.BI "Option \*qUseSIGIO\*q \*q" boolean \*q
|
|
This controls whether the Xorg 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 Xorg server, or
|
|
working around a specific bug until it is fixed, and understand the
|
|
consequences.

|
|
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.

The

section is used to specify which Xorg server modules should be loaded.
|
|
This section is ignored when the Xorg server is built in static form.
|
|
The type of modules normally loaded in this section are Xorg 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
|
|
or \(lqcyg\(rq prefixes, or the \(lq.so\(rq or \(lq.dll\(rq suffixes.
|
|
.PP

.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
|

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 (i.e. AutoAddDevices is
|
|
enabled). If hotplugging is enabled,
|

If hotplugging is disabled, there will normally

|
|
and one for the core pointer.

If there is no match there, the first

The
|
|
.B Identifier
|
|
entry specifies the unique name for this input class.
|
|
The
|
|
.B Driver

When an input device is automatically added, its characteristics are
|
|
checked against all
|
|
.B InputClass
|
|
sections. Each section can contain optional entries to narrow the match
|
|
of the class. If none of the optional entries appear, the
|
|
.B InputClass
|
|
section is generic and will match any input device. If more than one of
|
|
these entries appear, they all must match for the configuration to apply.
|
|
.PP
|
|
There are two types of match entries used in
|
|
.B InputClass
|
|
sections. The first allows various tokens to be matched against attributes
|
|
of the device. An entry can be constructed to match attributes from different
|
|
devices by separating arguments with a '|' character. Multiple entries of the
|
|
same type may be supplied to add multiple matching conditions on the same
|
|
attribute. For example:

will be loaded for each active
|
|
.B Device

|
|
.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.
|

.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., \(lqPCI:1:0:0\(rq 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 pciaccess tool
|
|
scanpci.
|
|
.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
|

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

boards with non-programmable 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 Xorg 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 Xorg 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

This entry is not used by many drivers, and it should only be specified if
|
|
the driver-specific documentation recommends it.
|

|
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.

.BI "TextClockFreq " "freq"
|
|
This optional entry specifies the pixel clock frequency that is used

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 may be used to provide information about the specifications of the
|
|
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:
|
|
|
|
.BI "Option \*qMonitor-" outputname "\*q \*q" monitorsection \*q
|
|
|
|
(for example,
|
|
.B Option \*qMonitor-VGA\*q \*qVGA monitor\*q
|
|
for a VGA output)
|
|
.PP
|
|
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 Mode ,
|
|
.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,
|
|
when they meet the requirements of the monitor.
|
|
.PP
|
|
The entries that may be used in
|
|
.B Monitor
|
|
sections are described below.
|

.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 Xorg 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
|
|
or
|
|
.B kHz
|
|
is added to the end of the line.
|
|
The data given here is used by the Xorg 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 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 makes 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

This entry is usually specified, but it may be omitted to create a match\-all
|
|

|
|
The range of

values that are allowed depends on the driver.
|
|
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
|

|
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

The server will delete modes from this list which don't satisfy various

.B Options
|
|
Option flags may be specified in the

.B Display
|
|
subsections.
|
|
These may include driver\-specific options and 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 \(lqserver layout\(rq 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 \(lqactive\(rq 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
|

Each

|
|
.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 .
|
|
The
|
|
.B ServerFlags
|
|
options (described above) may be specified here, and ones given here
|
|
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

|
|
.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
|
|
.B ServerFlags

When the same option appears in both places, the value given here overrides
|

the one given in the
