Cannot access Plasma Wayland session

[shishimaru]

Good day everyone.

I have a fresh installation of Tumbleweed with Plasma, but it’s impossible to login with the Wayland Session.

I can with X11, but unfortunately I’ve always had freeze issues, that’s why I prefer the Wayland one. I use the Nvidia proprietary drivers (I gave up and started to use them), version 560 with the Nvidia cuda repos for openSUSE.

What happens is: I can see the login screen (it’s SDDM I think?), I select the Plasma Wayland session, I input the password. The screen turns black, I get kicked back to SDDM.

I’m suffering of the same thing on another installation, seems that this happened after an upgrade, but I could rollback. I guess it’s related to KDE Plasma.

Is there anything we can do to at least investigate?

Do you happen to use an external display? I’m suffering the same:

Connection of external display (TV) forces/crashes back to login screen

AMD CPU and dGPU. Today I’ve been forced to use X11 (ew) because I’m suddenly – after an update yesterday I presume – unable to log into a Wayland session with an external display connected. In fact, I only definitely made this connection after disconnecting the HDMI cable and then being able to use Wayland without issue, only to be forced back/crash back into the login screen after connecting the cable again. I did find the following in /home/user/.local/share/sddm/wayland-session.log: Error…

Hah! Yes, external monitor. I can enter the session indeed if I unplug the DP cable! As soon as I re-plug it in, I get kicked again.

I’ve also tried to revert to the normal and default Breeze theme since that’s usually recommended.

Doesn’t work.

Newest updates has fixed it for me. Not the first time this has happened, so I’m not too surprised.
