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:
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. ...
