I will do that when I have enough time to task switch to that, but given
that it will slow down everything else I am doing it will probably not
happen until I have to make bigger changes.  That said, that might be
necessary to add the display-manager.service dependency.

Actually I do - it is because of our X11-only EGL library, which
gnome-shell doesn't like.  When I disable that both Wayland
(unaccelerated) and X11 (accelerated) sessions work.  The EGL library is
not doing much good anyway - I added it when Qt went EGL-only, but as
soon as I had added it they went back to GLX.  I don't think anyone will
miss it.

Will try to get those fixes committed tomorrow so that I can get back to
vboxvideo, updating from your v4 and looking at adding atomic.
