I'm trying to change my screen resolution to 1920x1200 with no luck. I actually did successfully change it, but once I log in it changes back to 800x600

The following has worked for me. Try running this on the command line:

First, make a backup of the config file:

cp /etc/X11/xorg.conf /etc/x11/backup.xorg.conf

Then configure the display to the resolution you want:

system-config-display --reconfig --set-resolution=1920x1200

You then have to restart X with ctrl-alt-backspace. I don't know of anyway to restart it on the command line but there could be a way. When I did this for the first time, I didn't restart X, and was mystified at why the resolution wasn't changing.
