Public bug reported: I used apt-get install nvidia-glx and edited /etc/X11/xorg.conf as nvidia website recomended. Everything worked fine. After that I installed driver from: Applications->Add/Remove..->System Tools->Nvidia binary X.Org driver after reboot XServer did not start, there was an error: "Screens not found" I edited xorg.conf (nvidia->nv) and after that everything worked OK but screen position is not correct. You cannot fix this by unchecking Applications->Add/Remove..->System Tools->Nvidia binary X.Org driver and doing apt-get remove nvidia-glx and after that apt-get install nvidia-glx. This happend with two different hardware configurations (and kernels): A8N motherboard with Athlon 64 3200+ CPU and Asus EN7600GS GPU P5B motherboard with Intel E6300 CPU and Nvidia Quadro NVS280 GPU
