An automatic fallback to X11 occurs if the Wayland session crashes
during startup. To help us find the cause of any potential crash, please
follow these steps:
1. Run these commands:
journalctl -b0 > journal.txt
journalctl -b-1 > prevjournal.txt
and attach the resulting text files here.
2. Look in /var/crash for crash files and if found run:
ubuntu-bug YOURFILE.crash
Then tell us the ID of the newly-created bug.
3. If step 2 failed then look at https://errors.ubuntu.com/user/ID where
ID is the content of file /var/lib/whoopsie/whoopsie-id on the machine.
Do you find any links to recent problems on that page? If so then please
send the links to us.
Please take care to avoid attaching .crash files to bugs as we are
unable to process them as file attachments. It would also be a security
risk for yourself.

Title:
System sometimes logs into X11 instead of Wayland
Status in gnome-shell package in Ubuntu:
Incomplete
Bug description:
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.
