So I wanted to try out Urban Terror on Fedora 18. I installed it. When I click it, the screen resolution would change to a lower resolution(800x600) to play the game in full screen. Then after I've exit the game the resolution would remain the same. I tried changing the resolution in the 'Displays' application to 1440x900, the screen would go blank forever and I would have to restart the PC. After restart the resolution would return to normal.
So after a few tries trying to replicate the issue, the screen went blank but after restart it never returned 1440x900. Now I'm stuck on the low 800x600. It does work on 1440x900 until login screen but after I login it goes to 800x600 that Urban Terror had set. Something seems to be broken after the login screen.
Forcing the resolution to 1440x900 in the /etc/gmd/Init/Defaults still doesn't change anything.
