Bug Description

With a fresh installation of Ubuntu 20.04.1,
adding the following to /etc/gdm/custom.conf

[xdmcp]
Enable=tue
ShowLocalGreeter=false

works fine. But with ShowLocalGreeter=true,
gdm3 does not show a login box to a remote X server.
journalctl -u gdm shows "GdmDisplay: Session never registered, failling"

If the combination of Enable=true and ShowLocalGreeter=true is unsupported,
Enable=true should also mean ShowLocalGreeter=false.
