This is the video card line on my system when I run the command: sudo
> /0/100/1/5 display RS485 [Radeon Xpress
> 1100 IGP]
Check this line, see what you have for a video card, and ensure you have
the proper (proprietary, in this case, ATI; you may have Nvidia; be
sure) driver loaded, and that you have System>Administration>Hardware
Drivers set to use the restricted drivers. Then reboot, and try
System>Preferences>Screen Resolution to see if you can properly set
them. It worked on the 2 machines I needed to do it on...
