#3: This is the commit you're talking about: https://gitlab.gnome.org/GNOME/gdm/-/commit/04e119c8332a564cfad05dfb9cb6ec547d5ba954 It's already /supposed/ to skip simpledrm devices.
However I just looked at a system on my side and I'm seeing a prefix of a PCI device now, so maybe that broke?

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.
