Comment 5 for bug 159750

Confirmed on my system (nv driver, GeForce4, CRT monitor capable of 1600x1200). I couldn't change the resolution with the Screen resolution dialog in Preferences. The Administration -> Screens and Graphics (or something like that) did change something, but I got a black and white X screen every time. After a reboot (and with the NVidia proprietary driver installed) the resolution was ok without my intervention.
