I'm on Ubuntu(studio) 20.4. with XFCE and everything was working fine. Last week I activated the backports to get some recent (audio) software and (possibly) since then I'm having some issues with the login. I realized that sometimes after entering the password the screen becomes black and the login window comes up a second time. Today the login window didn't come up at all and the screen was black for a minute or so. I could enter a second console and when switching back the login window was there.
In the journal I found the following lines:

So maybe there's an issue with lightdm. The same lines started emerging in the logfiles end of August which coincides with enabling the backports.
Can anyone help to get this solved?

I don'nt know if there's any connection, but I also had such logs in the journal since activating the backports:

What I did to solve this is described in this thread:
https://forum.ubuntuusers.de/topic/dconf-warnungen/
I installed the package dconf-cli and did:
sudo dconf update
