Can't unlock screen

[Tomi Leppänen]

I can't unlock screen after locking it. It's black and when I press a key or move mouse it shows my background and then turns black again. I can pass lock screen by killing gnome-screensaver in virtual console. I use Nvidia drivers (319.60-0ubuntu1) with GeForce GTX460.

This problem has been around for some weeks now, I think. I haven't used this computer too much lately.
