I'd already tried that one. That doesn't cause it to rescan the graphics card. 
For some reason, it no longer thinks my graphics card can handle more than 
640x480. When I call up the system administration screen, that's the only 
resolution it shows. I know it handles this correctly at installation. Note: 
I have a Dell Optiplex GX260 and am using the onboard graphics card. 

Any and all help greatly appreciated.
