I’m on an Ubuntu Gnome 64bit system with 16gb ram and two gtx560ti in non SLI mode (one for displaying contents, one solely for rendering) and a haswel i7. Since I am a Blender dev and we switched to CUDA 6.5 a day ago I had to update the NVIDIA drivers to the most recent version via your deb package. Install went flawlessly but I have drawing glitches now:
When I rename a file I can see the typed in characters sometimes directly, sometimes after a sec.
When I scroll on websites I often see the contents delayed. So even if my firefox is already changing the cursor to a hand (while being over a link), the webpage content is displayed as if I would not have scrolled at all. When I scroll further or selecting text, it’s refreshing - but most of the time it’s one step behind.
Had it one or two times that firefox was flickering completely - was gone after resizing it.
Thanks for the quick reply! I will definitely test this out this evening - I did a downgrade to be able to work again. But I’ll update soon and report back here!
So I tested it now and have to thank you, blackout24. With the PowerMizer to max, everything is working alright. Apart from that, I tested it with several desktop environments now:
Ubuntu unity is barely usable: massive flickering, heavily deferred drawing (sometimes 4 or 5 seconds freezes)
KDE is seldomly affected: This could be because it challenges the gpu more and it’s therefore less likely that PowerMizer is stepping down the frequency.
GNOME: The problems from the first post.
The question I have now is how to proceed. Is this GNOMEs & Unitys business or should NVIDIA fix here? Is there a bug tracker where I could notice NVIDIA about the problems in different desktop environments?
