Red Hat Knowledgebase

During installation, the system's monitor, video card, and display settings are configured. To change any of these settings for the system, use the X Configuration Tool.

To start the X Configuration Tool, select Main Menu Button (on the Panel) => System Settings => Display, or type the command redhat-config-xfree86 at a shell prompt (for example, in an xterm or GNOME terminal). If the X Window System is not running, a small version of X is started to run the program.

After changing any of the settings, log out of the graphical desktop and log back in to enable the changes.

When the application is started, it probes the monitor and video card. If the hardware is probed properly, the information for it is shown on the Advanced tab as shown in the following figure.



To change the monitor type or any of its settings, click the corresponding Configure button. To change the video card type or any of its settings, click the Configure button beside its settings.
