Ask Ubuntu is a question and answer site for Ubuntu users and developers. It's 100% free.

I'm using the latest proprietary Nvidia drivers (v. 302.17) on Ubuntu 12.04 LTS 64-bit and sometimes after returning from suspend I notice weird screen artifacts or sometimes screen is simply white. However, I'm able to unlock the screen and the desktop is displayed (usually) almost properly - sometimes only the left taskbar seems to be not refreshed fully. I upgraded to 3.3.7 kernel and then to 3.4.0-precise kernel from PPA mainline, but the problem still remains. The problem doesn't happen every time, often everything works fine.

I also noticed some random graphics hangs (screen/mouse freezes, but I can log in using ssh), but not very often.

Will the next version of Ubuntu address these problems? If it is an Nvidia bug, can you at least provide some workaround for this? It looks like some timing / race condition issue, because most of the time it works fine.

Hardware: Dell Precision M4600 , Nvidia Quadro 1000M

As explained here: askubuntu.com/questions/153691/…, you can count yourself lucky your computer is waking from sleep at all. It's a known bug on nvidias side and supposedly been worked on. However there's no ETA as of yet. You could downgrade to the previous version of the driver any time until this issue is fixed. I'd be very interested in a workaround as well. –  FuzzyQ Aug 1 '12 at 18:34
