I tracked down the cause, it has to do with sssd and how gdm3 handles it.
Similar issue:
https://bugzilla.redhat.com/show_bug.cgi?id=1534873

First I removed kerberos auth, which did not seem to have had an effect.
Then I saw that fprintd was showing errors and fprintd-list was throwing the same error as in the logs.

I removed it and after that it worked.
So it seems like a bug in sssd related to fingerprint auth, when that is not working properly.

Regarding evdi - as you wrote, can be addressed separately. As I wrote , it does NOT work properly for me, not the beta driver, not even on 5.13 with beta driver. I just installed 5.12 kernel and latest release driver because the beta does not work properly on my system - I use a D6000 Dell dock.

Regarding this bug - I will try to see if I can get frintd to work. I still have Ubuntu sessions showing that do not work, not sure where they came from, this is even after I purged gnome gnome-shell and gnome-session. can login now with gdm3 and gnome session.

Is there anything else you need to pursue this ?
