the xorg log seems to be strange, it tried to set those resolutions but failed.
Also not sure if I should see nouveau driver in the log? I checked nvidia-smi, it says no processes were using GPUs, I wonder if I was using the nvidia driver or nouveau.
Thank you very much. I indeed installed the “open” kernel nv driver, because I thought Nvidia recently opened their kernel driver.
I just installed the non-open version of the 520 driver through software & updates. But it was the same.
X11 log says (EE) no modes. And it tried to enumerate different resolutions but reported: “test failed”. I ran out of ideas, I’m planning to reinstall a fresh Os and try again. nvidia-bug-report2.log.gz (1.4 MB)
