I don't think I've seen X configured to run as root in probably 15 years. If anybody still does anything like that, they're literally asking for it.

  Hmm.. On my Debian ps axuw|grep Xorg says root 34595 2.7 0.4 26146280 532248 tty4 Sl+ Nov13 783:33 /usr/lib/xorg/Xorg vt4 -displayfd 3 -auth /run/user/1000/gdm/Xauthority -nolisten tcp -background none -noreset -keeptty -novtswitch -verbose 3

    That looks like the display manager (i.e. login screen) running on vt4, which is probably not where you are logged in. Does it switch to another user when you log in? Note you have multiple virtual consoles which can have independent X servers.

      No, that's actually my real and only Xorg, it's the child process of /usr/libexec/gdm-x-session and that process is owned by my real user id, and the Xorg process provides /tmp/.X11-unix/X1 that e.g. strace -e connect xlsclients shows is the socket it uses. Notice also that it uses a significant amount of memory and has consumed a meaningful amount of CPU time, much more than a dm would do. Good point about display manager though, I suppose it's not using Xorg then as I do know there is a login screen waiting at vt1 but that's the only Xorg process. Maybe the gdm3 incorporates a Wayland implementation in Debian 13.

      I think I ran into some display managers that do not start a new X session for every user. However I was trying out some rather non standard configurations at the time, some of which required root access for driver specific features.
