Thanks for that super fast response! Indeed this was the trick, sddm
works now again without setting the display-server to wayland.

I wonder what we could do in the mean time to save other users from this
pitfall?

Would it make sense to deprecate the `display-server` configuration
parameter in order to always default to xorg?

Or maybe just add a note to the manual:
