[centos] screen resolution setting


Hello?

In CentOS 5, how do I reset the screen resolution
in GUI manner?

Well, after changing the initial screen resolution
from 1024*768 to 800*600, I cannot go back to 1024*768.

This resolution (1024*768) is no longer available in
the drop down choice (system -> preferences -> screen resolution).

Thanks.

So boot or switch to runlevel 3 and fix it, as root type something like;

cp /etc/X11/xorg.conf /etc/X11/backup.xorg.conf
system-config-display --reconfigue --set-resolution=1024x768 --set-depth=16

The first typed command makes a backup of the currect xorg.conf file just in case (always a good idea). The second resets or reconfigures the xorg.conf file.

Just spotted a small typo in this. --reconfigue should be --reconfig like so:

cp /etc/X11/xorg.conf /etc/X11/backup.xorg.conf
system-config-display --reconfig --set-resolution=1024x768 --set-depth=16
