I have recently installed Ubuntu 15.04, and with it the latest stable version of the nVidia Display Driver (352.55) for my GTX 650, downloaded from the community nVdia driver repository.
After setting my resolution to 1360x768 (I have a 16:9 monitor), though, the screen looks stretched horizontally and the rightmost part of the displayed image is not shown on the monitor. Vertically, the image is displayed fine and doesn't look stretched.
If I take a screenshot, the size of the saved picture is 1360x768, which means the resolution is correctly set, it will simply look stretched beyond my monitor's display area.
I've searched Google for days, but I simply cannot find a solution for this. Can anyone provide help?
