102 Chapter 7. X Servers and Clients

Files

This section sets paths for services vital to the XFree86 server, such as the font path. Common

options include:

• FontPath — Sets the locations where the XFree86 server can ﬁnd fonts. Different ﬁxed

paths to directories holding font ﬁles can be placed here, separated by commas. By default,

Red Hat Linux uses xfs as the font server and points FontPath to unix/:7100. This tells

the XFree86 server to obtain font information by using UNIX-domain sockets for inter process

communication.

See Section 7.5 for more information concerning XFree86 and fonts.

• ModulePath — Allows you to set up multiple directories to use for storing modules loaded

by the XFree86 server.

• RgbPath — Tells the XFree86 server where the RGB color database is located on the system.

This database ﬁle deﬁnes all valid color names in XFree86 and ties them to speciﬁc RGB

values.

InputDevice

Conﬁgures an input device such as a mouse or keyboard used to submit information into the sys-

tem using the XFree86 server. Most systems have at least two InputDevice sections, keyboard

and mouse. Each section includes these two lines:

• Driver — Tells XFree86 the name of the driver to load to use the device.

• Identifier — Sets the name of the device, usually the name of the device followed by a

number, starting with 0 for the ﬁrst device. For example, the ﬁrst keyboard InputDevice

would have an Identifier of Keyboard0.

Most InputDevice sections contain lines that assign speciﬁc options to that particular device.

Each of these lines start with Option and contain the name of the option in quotes, followed by

the value to assign to that option. Mice usually receive options such as Protocol, such as PS/2,

and Device, which designates the mouse to use for this section. The InputDevice section is

well commented, allowing you to conﬁgure additional options for your particular devices by

uncommenting certain lines.

Module

Tells the XFree86 server which modules from the /usr/X11R6/lib/modules/ directory to

load. Modules provide the XFree86 server with additional functionality. You should not edit

these values.

Monitor

Refers to the type of monitor used by the system. While one Monitor section is the minimum,

there may be several Monitor sections, one for each monitor in use with the machine.

Warning

Be careful when manually editing values in the options of the Monitor section. Inappropriate

values in this section could damage or destroy your monitor. Consult the documentation that

came with your monitor for the safe operating parameters available.

The following options are usually conﬁgured:

• HorizSync — Tells XFree86 the range of horizontal sync frequencies compatible with the

monitor in kHz. These values are used as a guide by the XFree86 server so that it will know

whether to use a particular Modeline entry’s values with this monitor.
