gnome-shell should automatically fallback to locking using gnome-screensaver (via dbus activation) when you are not using gdm. So unless things
have changed recently the only requirement is to have gnome-screensaver package installed.

It would be good, lightdm have a "org.freedesktop.login1.Manager" dbus interface which despite the name is not a spec, which works ok as a
fallback but you loose all DE integration. I'm not sure upstreams would take a fallback solution and coming up with a standard which allows for
the required integrations seems like it would be difficult.
