@generix, I used the command sudo apt install nvidia-driver-525, rebooted, and the NVIDIA settings dialogs shown the same.
However my 2nd display is working fine so I would prefer not to touch anything except that you have a strong reason to.
I include the new log file in case it is of help to diagnose the problem:
nvidia-bug-report.log.gz (158.1 KB)
Just to be cautious from now on, what is the next step? I guess I should wait until a newer driver is released (newer that the 545.23.06 BETA, which also didn’t work for me), and then try again. If it doesn’t work, I can always come back to the current 525 I’m using now, sounds good?
