Troubleshooting Your Video Card

Video card configuration is handled during the Red Hat Linuxinstallation (see the Official Red Hat Linux Installation Guide). However, if you did not choose to configure a video card at that time, or if you need to reconfigure your settings, you can use the Xconfigurator utility. You will want to do this if you, for example, install a new video card.


Xconfigurator will overwrite your system's original video configuration file. As a safety measure, be sure to make a backup of the /etc/X11/XF86Config file before running Xconfigurator.

To run Xconfigurator, log in as root and type Xconfigurator at a shell prompt. Follow the instructions that appear on the screen. Make your selections using the [Tab] and [Enter] keys.

When you have finished reconfiguring your video card, log out of root and log back in to your user account.
