https://bugs.freedesktop.org/show_bug.cgi?id=69827 --- Comment #1 from Ilia Mirkin <imirkin at alum.mit.edu> --- Does this still happen with the latest software, i.e. kernel 3.10, mesa 9.2, xf86-video-nouveau 1.0.9? (Kernel 3.11+ apparently has some issues for some NVC1 users, although feel free to try it.) Also, does this happen on an untainted kernel? (i.e. without virtualbox modules ever being loaded). Lastly, you can use 'perf' (in tools/perf in the linux-kernel sources) to tell where cpu time is going. Running perf record -g -p $gnome_shell_pid; perf report may be instructive. -- You are receiving this mail because: You are the assignee for the bug. -------------- next part -------------- An HTML attachment was scrubbed...
