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 ? ** Bug watch added: Red Hat Bugzilla #1534873 https://bugzilla.redhat.com/show_bug.cgi?id=1534873 -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1960336 Title: No login screen after recent update To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gdm3/+bug/1960336/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
