Joachim: if you have an nVidia card, you can search for "nvidia-glx" in Synaptic, and look at the installed version number there. However, I doubt that this problem has to do with the driver version, after all. Do you also have a Dell laptop?
I've also noticed that the problem doesn't seem to be related to hibernation, as I thought first. It's just that I usually hibernate and resume once per day. However, I've noticed that it (at least usually) happens when the daily updatedb is run. -- Screen occasionally offset to the left https://launchpad.net/bugs/75214 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
