    The display is using an Nvidia card (Quadro RTX 4000) with proprietary driver version 430.50.

    I noticed it was crashing when trying to launch a session on the physical display as well, so I reinstalled the nvidia driver and that appears to have resolved the issue.  I now see the GPU when connecting via nomachine and it appears to be working.

    The only issue I see now is that it can’t launch nvidia-settings as it fails with “ERROR: Unable to load info from any available system

    Thanks for your help!

    Thanks for your help.  I followed the linked instructions to install lightdm, and that allowed me to connect to the session. Unfortunately now I see only a black screen.
