X Window System Configuration
During installation, the system's monitor, video card, and display settings are configured. To change
any of these settings after installation, use the X Configuration Tool.
To start the X Configuration Tool, go to Applications (the main menu on the panel) =>
Administration => Display, or type the command system-config-display 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.

31.1. Display Settings

The Settings tab allows users to change the resolution and color depth. The display of a monitor
consists of tiny dots called pixels. The number of pixels displayed at one time is called the resolution.
For example, the resolution 1024x768 means that 1024 horizontal pixels and 768 vertical pixels are
used. The higher the resolution values, the more images the monitor can display at one time.
The color depth of the display determines how many possible colors are displayed. A higher color
depth means more contrast between colors.
