Distribution-specific tools

Various Linux distributors provide their own configuration utilities. For example, system-config-display is distributed by Red Hat Software. It is an X-based GUI tool that can probe graphics chipsets and features. In Red Hat Fedora 10, the xorg.conf file was dropped. Instead, the operating system detects system components and configures the X system accordingly every time the system boots. If you need to configure a system component manually, you first need to create the xorg.conf file. This can be accomplished using different tools, such as the system-config-display package if it is installed. This can be run interactively as root from the command line, or it may be run from the display command in the System Administration Display menu. In either case, the graphical interactive control for video driver and monitor selection will open. You can install the system-config-display package using a package controller such as yum. Refer to Chapter 5 for more information about installing packages. To run the system-config-display package from the terminal, type the following:

# system-config-display

The alternative is to manually create and edit the xorg.conf file. This may be done using the xorg –configure command, which will create a basic new xorg.conf file using information that is autodetected from the system. The file will be created in the local directory.

Example 14-2 shows the creation of the xorg.conf file using the –configure option in Fedora Linux. ...
