Public bug reported: This happened to me after upgrading to Ubuntu 25.04, but also on a fresh installation:
I have an all AMD-system and noticed that from time to time, Ubuntu logs into an X11 session, instead of the default Wayland session. This happens maybe every third to fourth login. This never happened to me before on Ubuntu 24.10 (or Ubuntu 24.04), so I assume it's a bug in Ubuntu 25.04.
