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 desktop.
The color depth of the display determines how many possible
colors are displayed. The higher the color depth, the more contrast
between colors.
