That is not entirely right, the GUI for gdm is actually a cut-down
gnome-shell session, this applies to both lock screen and greeter. gdm
does however handle all user authentication, which is a little different
from how lightdm work afaict (Robert correct me on this If I am wrong).
When we started Ubuntu GNOME, gdm was problematic on Ubuntu, I spent
alot time working with halfline (ray) to iron out the issues and
everything is upstream. These days its pretty stable and works perfectly
in most cases. Although lightdm does seem to handle better the corner
cases where openGL config is broken for whatever reason.
I probably don't know enough about lightdm code to make a proper
comparison, but if you have lightdm running the gnome-shell greeter, and
replicating the auth channels and user switching interfaces to make it
compatilbe with gnome shell (without patches). What technical reasons
remain ? So far as I can tell its really only the tests?
