Hello i have used Ubuntu 12.04 for some time now but now i have encountered a really annoying problem that drives me crazy. I first got this problem when i updated my nvidia drivers, version 331 recomended. I also tried the none recomended version. The problem is that the xserver freezes, the computer itself is fine and the only problem is that "unity" freezes. The problem can be solved by simply do [ctrl+alt+(F1-F6)] and the [ctrl+alt+F7] in order to restart the xserver. Ubuntu works fine with "Unity2d" but the taskbar(The bar to the left) takes up way to much space. I posted this question some time ago but i gave up. I have reinstalled ubuntu but the problem remains.
Why does this happen? How can i fix this problem?
Is it indeed the drivers that is the cause of this problem? or is it possible that it might be a graphic card failiure? Or any other reasons for this to happen?
How likely is it that the problem remains on Ubuntu 14.04 LTS ( Since i am planning on an upgrade)
