Public bug reported:
I have a Samsung SyncMaster B2030, its native resolution is 1600x900,
everything was good until I launched Steam, it changed the resolution,
and since the resolution remains 1024x768 ... In parameters, this is
indicated that the screen is unknown.
It doesn't give me the opportunity to activate the native resolution
(1600x900) and my attempts are unsuccessful with xrandr.
Here is my lat attempt :
o@os-desktop:~$ cvt 1600 900 60

I tryed reinstalling my GC driver, and also generating a new xorg.conf,
the problem remains.
