Chapter 32. X Window System Configuration
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
(the main menu on the
panel) => => , 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.
The Display 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 are used and 768 vertical pixels are
used. The higher the resolution numbers, the more images the monitor can
display at one time. For example, the higher the resolution, the smaller
the desktop icons appear, and the more icons it takes to fill the entire
The color depth of the display determines how many possible colors are
displayed. The higher the color depth, the more contrast between colors.
