Logout goes to black screen

I’m running Tumblweed, so the system updates automatically every 2 or 3 days. In the later part of October (probably after an update) user logout started going to a black screen where just the mouse pointer moved and nothing else worked until the system was shutdown and re-started. The system automatically logs in as me on startup, so I can’t logout and login as root, however I can run YAST from my user account. Is there a setting that might have gotten changed in one of the updates that I could access to fix the logout or change the booting to allow a choice of user?

Which display manager are you using? Do you really need to be logging in and out of the desktop environment as root user?

I love that the first answer is “why are you doing it different than me” instead of being helpful.

I’m having the same issue as OP on a fresh install

Considering logging into a Graphical Session as the root user is pretty close to universally considered a “Bad Idea™” it’s a perfectly legitimate question to be asking.

Have you tried to switch to Console 1, using “Ctrl Alt F1”, the login as root there? Then you can toggle back to the “Graphical Console” when done with root. (example, “Ctrl Alt F2”).

The other option is to open a graphical (windowed) console (such as Konsole if using Plasma), then jump to a root user session (such as “:~> su -l”).

Which desktop environment and login manager are you using?

Do you really “logout”? How is the system shutdown if you “can’t logout and login as root”? What do you do on this black screen to shutdown the system? Your description is rather confusing.

Using GNOME, Plymouth shutdown screen is not started when I request shutdown from within GUI session and also no usual messages from systemd are shown. It started to happen recently. I did not care enough to investigate it.

I just fired KDE VM, and here I get the usual Plymouth screen.

And today I also do not see this in GNOME VM either. Not sure whether it was temporary glitch on my side or something has really changed.

Thanks everyone for your replies and suggestions. I’m using KDE and I usually logout of the system instead of shutting it all the way down if I’m going to be using it again in a little while. I rarely log in as root, but was using that as an example.
The problem seems to have fixed itself with a recent Tumbleweed update. I’ve used Tumbleweed for a few years and occasionally one of the upgrades won’t complete because of some package conflict, but this is the first time an upgrade caused a problem.
Again, thanks for your replies.
