Fine-Tuning Your Display Configuration
Fedoraâs Anaconda installer detects and configures most display hardware optimally. However, there are some situations where itâs necessary to override the default configuration to set up a desired display resolution and color depth.
How Do I Do That?
Fedoraâs display configuration program is called system-config-display.
If you have a working graphical display, you can start this program by selecting SystemâAdministrationâDisplay from the panel menus (System SettingsâDisplay in KDE). Youâll need to enter the root password when prompted.
If you donât have a working graphical display, or youâve booted into character mode (see Lab 4.5, âUsing Runlevelsâ), you can start this program from the command line:
$system-config-display
You are attempting to run "system-config-display" which requires administrative privileges, but more information is needed in order to do so. Password for root:
secret
The graphical display will be started in a very basic mode so that the graphical configuration dialog can be displayed.
Tip
system-config-display uses the existing display configuration as a starting point. If the existing configuration does not work at all, you may need to delete it to force system-config-display to start from scratch:
# rm /etc/X11/xorg.conf
Whether started from the menu or the command line, the window shown in Figure 2-15 will be displayed.
