Sddm fails to load desktop after login

[bearcat]

I installed SDDM on Manjaro XFCE following instructions on the Manjaro wiki for sddm:

Install Display Managers

What happens:

On startup I reach the SDDM login screen. I can enter my password. The login screen then freezes without proceeding to the desktop starting as it should. How would I fix this?

Some output follows where I checked the status of sddm:

The last lines output below might indicate some problem with Authorization. What might be the problem here? Did the wiki instructions leave out some necessary step? There are no onscreen error messages to suggest what is wrong.

This seems relevant.

I saw both of your threads lightdm and here.
So, I think the problem is not the display-managers, but your system.

Lightdm fails to start after Dec. 6 updates

Thanks for your attempts to help here, but I decided to install sddm. I encountered a (hopefully) minor problem with that which I could not solve. I started a new thread about it.

You may be right, but I doubt it, because the Manjaro XFCE OS has been installed for years, and only showed this problem when rebooting after the Dec 6. updates. There is also a Manjaro MATE that dual boots with the Manjaro XFCE and there was no problem with MATE after the same updates.

I will test that suggestion as soon as possible. Thanks.
