No.  Users can run vncserver and attach to them like you could before,
or you can run Xvnc -inetd, just as a systemd service/socket pair
instead of out of xinetd.

The black screen problem that you mentioned does sound familiar --
I've seen it with VNC clients that don't support OpenGL, with the
GNOME desktop (which uses a compositing display manager), it just
crashes when you log in.
