Title:
Screen corruption with Radeon 6670
Status in “xserver-xorg-video-ati” package in Ubuntu:
Confirmed
Bug description:
Unfortunately I have no reliable way of reproducing this issue, but it
seems that after some time of using Ubuntu (especially when browsing
websites with firefox) the graphics are getting corrupted.
It starts with some small artifacts (single lines and pixels) and all
of the sudden the entire screen is full of artifacts and the OS is
basically unusable at this state.
Coincidentally, I've had this problem with Arch Linux before. I was able to
fix it, by setting the power profile of the GPU to "mid" or "high" as described
here: https://wiki.archlinux.org/index.php/ATI#Profile-based_frequency_switching
So to me it seems like this might be related to power management.
Doing some more testing with Ubuntu, I was able to fix the corruption
when switching the profile to mid and then logging out and in again.
Leaving the profile at default did not fix the issue after re-login.
