gdm 3.22.3 adds the option of some non-user display server stuff. This was always forced by 3.22.1, but can now be disabled or something in 3.22.3. I didn't yet figure out what all this was about, so this is a bug to not forget to re-review by me or someone else. Haven't seen any bug reports about root required display server or whatever, so hopefully this doesn't have any real issues, just options.
Still not sure what it's exactly meant to do, but it's required for login screen reaping to work with wayland (saving 200+ MB of RAM by killing the gnome-shell login UI stuff when not in use)
I think this reaping is working fine right now. What else is there to do with this bug?
Seems everything has been working well.
