    This works, but still requires the me to physically sit at the terminal to log into gdm3 to get XAUTHORITY before I can do any remote work. If I ssh in before logging in with gdm3, the service fails. I work around this by using AutomaticLoginEnable=True and AutomaticLogin=stew in /etc/gdm3/daemon.conf.

    The solution is to make sure no processes for the logged out user remain running, by executing killall -9 -u $USER after logging out, for the user that just logged out. To apply this solution to fix the "can't login after logout" issue, the command I mentioned needs to run after you select to logout from the Gnome System menu.

    This gdm3 daemon is not compatible with XDMCP for remote access. Its reliance on Wayland (rather than the X11 protocol) will cause issues, and screen output may be scattered on the console after login. You can resolve this issue by installing the lightdm display manager and the Xfce desktop environment rather than using gdm3 and Gnome respectively.

    gdm3 reads /etc/gdm3/custom.conf for its configuration. For each local display, gdm starts an X server and runs a minimal GNOME session including a graphical greeter. If configured so, the main gdm process also listens for XDMCP requests from remote displays. These requests can either be direct, causing gdm3 to start a session on the remote display, or indirect, causing a chooser to be opened.
