Great, thanks for identifying! So yes this fix should definitely go back to
Noble then too.
I'll assign the Questing task to you to time with your other GDM work, and then
you guys can handle the SRU after that.

Bug description:
After upgrading to Ubuntu 25.04 my laptop fails to properly start the
gnome login shell. During boot I see the graphical splash screen as
expected, but once the login screen should show, one of the below
things happen:
- Nothing, I keep seeing the boot splash screen.
- The login screen is rendered, but only a single frame. Moving the mouse or
pressing keys has no effect.
- The login screen is rendered and the mouse cursor moves, but none of the
widgets respond to clicks or pressing keys.
To recover, I have to Ctrl+Alt+F2 and login on the terminal interface.
Then I can do a `sudo systemctl restart user-120.slice` after which I
can go back to the GUI login screen and it works.
