Same here, already some time. Sometimes I get it to autologin when I re-configure it in plasma's configuration, but then after a while I am back to console login

Some more discussions here: https://forums.opensuse.org/t/plasmawayland-sddm-autologin-is-broken/152845/12

After a failed login attempt (back on tty login), I try to start sddm manually and get the following log from journalctl

I think this should be moved to the Tumbleweed product, since I can reproduce on a new installation on the latest packages on TW.

I have such a problem that when logging out I can't change the xorg or wayland session. If I go from wayland to xorg, then I have a black screen with a cursor and also vice versa.

Looks like this issue got fixed again with Plasma 6.1 update. Works fine here after the update.
