Turns out high CPU Usage and slow UI issue is unrelated, it was due to CPU governor reset to powersave and always using min frequency.
But the issue with nouveau timeout and system lockup still stays I guess. Unless it was triggered by low CPU frequency. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to xserver-xorg-video-nouveau in Ubuntu. https://bugs.launchpad.net/bugs/1901294 Title: nouveau timeout and system lockup Status in xserver-xorg-video-nouveau package in Ubuntu: New 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.
