Comment 35 for bug 1032187

I can confirm that the bug is also present in an older version of the nvidia-graphics-drivers, since I have used an older version in the past. I am pretty sure it was 295.40. I was hoping that the 302 drivers would have fixed it, but obviously they don't. I will try the nouveau drivers at a later moment.

I also noticed something when I was testing all these different sessions. Usually the bug has appeared after some time of NOT using my pc. Can it be related to my monitor being switched off? It does not happen every time the monitor goes into standby (I can't reproduce it that easily), but it seems to be correlated. In the xorg.0.log I also see some lines like indicated below, that appear after monitor standby (repeats several times with different code):

[251458.928] (II) NVIDIA(GPU-0): Display (Samsung SyncMaster (DFP-0)) does not support NVIDIA
