[LightDM] Trying light dm.

[Robert Ancell]

Hi Stef,

Thanks for your email.  Discussions are best on the mailing list
(lightdm at lists.freedesktop.org), so I've cc'd it here.

Yes, there are a number of greeters, you can also try the GTK+ greeter
[1].  Also have a look at /var/log/lightdm/x-0-greeter.log to see what
the greeter logged.

Let us know how you go,
--Robert
