I seem to have the same problem with a GeForce 8800 GT card. Let me know if I can help. See https://bugs.launchpad.net/bugs/1111884 Pontus You've mentioned in bug 59057 > Pontus Fuchs 2013-03-11 19:57:13 UTC > Suspend / Resume working again with Linus' master git. Assuming that this is the same system, has the issue regressed again ? I'm assuming that the issue may not have been fixed and was worked around by disabling "desktop effects".

The symptoms are similar to bug 59057 but not identical. In bug 59057 the screen was completely blank after resume. In this bug the screen is first restored but everything is frozen except for the mouse pointer. Since the symptms where not identical I decided to file a new bug. Can you isolate(bisect) the offending commit ? (In reply to comment #4) > Can you isolate(bisect) the offending commit ? It's not really possible :( The complete story goes like this: 1. Back in 3.7 everything was working fine. 2. In 3.8-rc2 resume was not working with the black screen problem 3. After some time the black screen was fixed but I now had the problem described in this bug. If I bisect to a completely working system I'll end up before 3.8-rc2 as in bug 59057. Hi! Regarding suspend/resume scrambling screen issues, try this patch: [PATCH] drm/nouveau/fb: fix suspend/resume fbcon http://lists.freedesktop.org/archives/nouveau/2013-October/014656.html chr[] (In reply to comment #6) > > Regarding suspend/resume scrambling screen issues, try this patch: > > > [PATCH] drm/nouveau/fb: fix suspend/resume fbcon > > http://lists.freedesktop.org/archives/nouveau/2013-October/014656.html > Hi, I tried your patch but it does not solve my issue :( //Pontus The patch doesn't help me either. :-/ I finally managed to bisect this problem.
