** Description changed: 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. + Setup: Ubuntu 20.10. nouveau. Wayland. nVidia GTX 1080 Ti. Intel Xeon + E3-1231 v3. dmesg output attached.
