Title:
nouveau timeout and system lockup
Status in xserver-xorg-video-nouveau package in Ubuntu:
Confirmed
Bug description:
After upgrading from 20.04 to 20.10 system is unusable anymore due to
GPU issues with nouveau. Same system worked fine on 20.04.
Switching to nvidia proprietary driver and Xorg fixes the issue.
Symptoms:
System starts just fine, but overall UI performance is bad, everything
seems slow and CPU usage seems too high even when idle. After a while
UI freezes completly. Sometimes it recovers after several minutes,
other times it doesn't and system freezes forever, requiring hard
reboot.
Setup: Ubuntu 20.10. nouveau. Wayland. nVidia GTX 1080 Ti. Intel Xeon
E3-1231 v3.
dmesg output attached.
