Forget to mention: Xorg-server is 7.4 from Fedora 14 stock graphics adapter is nvA0 Can you post dmesg please. Also, any chance of finding which commit is responsible. Thanks :) Logs do not contain anything interesting. But I bisected the issue today. It seems the problematic commit is 5f6fdca570b13a8a2c9cab9ab6edfc17487049cf Can you try drm-nouveau-staging, there's a fix to nouveau_mm.c that appears to fix the issues I seen on my NVA0. Yes, code from drm-nouveau-staging seems to fix it. I used this for several hours now and haven't seen any corruption. |

Created attachment 41786 [details] Example of screen corruption If I use drm-nouveau-next instead of master I get massive screen corruption after some minutes working with X. The corruption never appears directly after starting X, it takes several minutes to show up. Restarting X hides the problem for a few minutes before the corruption reappears. DDX and libdrm are from git as of 08-Jan-2011. I tried to use "EXAOptimizeMigration" "off" in xorg.conf, but this has no effect.
