First of all, this has nothing to do with your display/monitor, ‘screen’ means just the useable surface of your desktop.
The problem is that the Xserver is incorrectly trying to enable AIGLX using mesa which obviously doesn’t work since you’re using the nvidia driver.
I don’t know if this is connected to the issue but on system boot, the nvidia drivers get loaded, then unloaded and loaded again, maybe due to the in the logs mentioned nvidia-docker, don’t know, looks bogus, might be a timing issue which is surfacing with the newer drivers.
Two things to try to work around the issue:
- backup and remove xorg.conf
- if that doesn’t work, put back xorg.conf and add
Option "AIGLX" "off"
