-.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

-.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

-.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.

-.PP
-.RS 4
-.nf
-.BI "Section \*q" SectionName \*q

-The old
-.B XInput

-.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

-.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

-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

-Each
-.B Screen
-section may optionally contain one or more
-.B Display
-subsections.
-Those subsections provide depth/fbbpp specific configuration information,
-and the one chosen depends on the depth and/or fbbpp that is being used for
-the screen.
-The
-.B Display
-subsection format is described in the section below.
-
-.SH "DISPLAY SUBSECTION"
-Each
-.B Screen
-section may have multiple
-.B Display
-subsections.
-The \(lqactive\(rq
-.B Display
-subsection is the first that matches the depth and/or fbbpp values being
-used, or failing that, the first that has neither a depth or fbbpp value
-specified.

-.TP 7
-.BI "Depth " depth
-This entry specifies what colour depth the
-.B Display
-subsection is to be used for.
-This entry is usually specified, but it may be omitted to create a match\-all
-.B Display
-subsection or when wishing to match only against the
-.B FbBpp
-parameter.
-The range of
-.I depth
-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
-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.

-the virtual display area.
-.TP 7
-.BI "Modes \*q" mode\-name \*q " ..."

-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

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.

+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

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
