I've recently installed Ubuntu 11.10 on my PC and I have a resolution problem.
My screen resolution is set at 640x480 (4:3) and I can't see right the whole screen, the windows or the icons. The problem is that it does not have other options in monitor->display so I can choose the right one, and I think that it can't detect my monitor - it says "unknown"(i have a desktop with pentium4, at 3Ghz, asus motherboard and an Nvidia GeForce graphic card).
xrandr: Failed to get size of gamma for output default Screen 0: minimum 320 x 240, current 640 x 480, maximum 640 x 480 default connected 640x480+0+0 0mm x 0mm 640x480 50.0* 320x240 51.0
