As far as I know the only thing that affects screen resolution that
cannot be done with in system-config-display is the video card
identification. But as always I am willing to learn something new.

Well now I'm not sure at all.  I just checked my system-config-display and the only resolutions available are 640x480 and 800x600.  Considering I'm running my laptop screen at 1920x1200 looks like we're both wrong.  But i'd put my confidence in what's in the xorg.conf file rather than what system-config-display says.

Cheers,
Dylan
