Configuration Using Xconfigurator

A configuration file named XF86Config controls the operation of X. Linux places this file in the /etc/X11 directory. You can edit this file by using pico or another text editor; but it’s much easier to use Xconfigurator, which asks a few questions about your system and then builds the file for you.

To launch Xconfigurator, log in as root and type the command:

Xconfigurator

Xconfigurator displays its opening screen, shown in Figure 5.1. The configuration process that ensues is very similar to the one performed by the install program; but, as you’ll see, there are a few differences, mostly minor. Select the Ok button and press Enter to continue.

Warning

Xconfigurator overwrites the contents of the XF86Config file. If you already have a working X setup, you should create a backup copy of XF86Config before running Xconfigurator.

If the probe fails, you should suspect that you installed an X server that’s not compatible with your video card; install the proper server and try running Xconfigurator again. If the probe succeeded, you can select the Ok button and press Enter.
