Xorg/xfce not running with Nvida graphics on first login

Hi list members,

I have a bit of a strange problem here. This is a home theater system, running latest Mint and a GeForce GTX 1650 with the recommended latest Nividia driver. At first, this was just working well out of the box. Then I must have changed something, which made things odd. On boot, a default user is automatically logged in with no password.

  • Graphics looks a bit rough, but somehow works. The resolution and identified monitor is not what would be expected.
  • Nvidia kernel module is loaded.
  • nvidia-smi does not show any running processes. There should be /usr/lib/xorg/Xorg and xfwm4 running.
  • nvidia-settings reports “unable to load info from any available system”.
  • Audio via HDMI is shown as “unplugged” in the Pulseaudio settings, so does not work at all.

Now, I can log off from this session and wait for the next automatic login. Exact same user, no reboot, just log in again: All is fine.
Any idea, what happens here?

Please run nvidia-bug-report.sh as root and attach the resulting nvidia-bug-report.log.gz file to your post.

Will attach nvidia-bug-report later today, as this machine is streaming right now. I need to reboot this to get it back in the non-functioning state.
