Graphics Administration Guide (July 2008)

NOTE: Hex integer values must be prefixed with “0x”, and octal values with “0”.
A special keyword called Option may be used to provide free-form data to various
components of the server. The 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:
• Integer - an integer number in decimal, hex or octal
• Real - a floating point number
• String - a sequence of characters
• Boolean - a boolean value (see below)
• Frequency - a frequency value (see below)
NOTE: All Option values, not just strings, must be enclosed in quotes.
Boolean options may optionally have a value specified. When no value is specified,
the option's value is TRUE. The following boolean option values are recognized as
TRUE:
1, on, true, yes
and the following boolean option values are recognized as FALSE:
0, off, false, no
If an option name is prefixed with “No”, then the option value is negated.
Frequency option values consist of a real number that is optionally followed by one of
the following frequency units:
Hz, k, kHz, M, MHz
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.
ServerLayout section
The ServerLayout section is used to identify which Screen sections are to be used in a
multi-headed configuration, the relative layout of those screens, and which InputDevice
sections are to be used. Each ServerLayout section has an Identifier, a list of Screen
section identifiers, and a list of InputDevice section identifiers. Options may also be
included in the ServerLayout section. A ServerLayout section may be made active by
referencing (via its Identifier) on the command line that starts X. In the absence of this,
the first one found in the file will be chosen by default, as there may be multiple
ServerLayout sections in the config file. The format of the ServerLayout section is as
follows:
