I somehow managed to make it work using lightdm-gtk-greeter, but it doesn't autoload Unity and I dont' have the indicators that appeared before.
I started Unity using unity --replace in Guake and this is what I get: WARN 2014-02-24 22:05:37 unity.glib.dbus.server GLibDBusServer.cpp:579 Can't register object 'org.gnome.Shell' yet as we don't have a connection, waiting for it...
