I have a fresh install of ubuntu 20.04 and I have a GTX1080. The system worked smoothly at first, but as soon as I installed nvidia driver it became very slow. Heavy stuttering can be observed even when moving the curser, the system often got completely frozen (I have to cut the power when this happens.).
I tried both 450 and 455 drivers, both had the same problem. But the xorg nouaevu drivers is fine.
I suspect this is a hardware issue, something like the graphics card or the power supply is faulty. How should I diagnose?nvidia-bug-report.log.gz (283.1 KB)
