Bug#725871: xserver-xorg-video-nouveau: Graphical corruption after resume from suspend or hibernation

["A. B." <moijaiunvelo@gmail.com>]

I have tested with a 3.11 kernel (3.11-trunk-686-pae, 3.11-1~exp1 (2013-09-12)) and the problem persists. I am going upstream, thank you once again for your answer.

Supplementary information : Most of the graphical corruptions can be overcome by restarting impacted applications (in my case : openbox/tint2 and iceweasel) so the importance of this bug is not as high as I indicated first. Moreover the appearance of corruptions is erratic so it may be hard hard to reproduce them. The most repetable corruption on my system is the corruption of iceweasel's tabs after resizing the window : I did not succeed in suspending/resuming the system without experiencing this corruption.

Sincerly,

Moi

Could you please test with a 3.11 kernel from experimental?  If the
problem persists, file a bug upstream.  See
http://nouveau.freedesktop.org/wiki/Bugs/ for instructions.
