However when I logged in, the screen went back, stay so for one minute
or so and then I was back to sddm prompt.
So I though some pacage where missing and did an experimental upgrade
from console login. I saw that some packages like dokphin, kwrite,
kgamma, ... were missing and installed them.
Just to discover that this did not fix the problem. So I was about to
change my session type to fvwm that I keep when kde breaks, just to
realize that during sddm upgrade, the session type was not set to
plasma-x11. Changing it back to it, made login work successfully.
For what it's worth, I had this too with Wayland. I have an old Nvidia
adapter. The X11 session type works fine for me.
