[LightDM] systemd cooperation

[Robert Ancell]

Confirmed. Thanks Martin!

The cause seems quite clear now, LightDM is not detecting the VT switches
so when the session exits LightDM thinks it is a background session and
doesn't start a greeter (it thinks you are looking at the other session).
The reason I haven't seen this is we are using the switch D-Bus calls in
LightDM for VT switching in Unity and so LightDM knows which session is
active. Using ConsoleKit or logind or doing the VT switches manually will
trigger the problem.

I think this may be the cause of:
