Bug Description

For some reason on a system upgraded from Natty the file /etc/X11/default-display-manager does not exist.
In this situation, gdm and lightdm are both started and gdm is the greeter.

Expected:
1. Lightdm is the default if there is more than one display manager and no default set
2. /etc/X11/default-display-manager is always created when lightdm is cofigured.

/etc/X11/default-display-manager is present on the natty desktop images, and also on my systems which were upgraded from natty. It's not clear to me how it got lost in the first place.

I think we can handle this corner case a little more gracefully in gdm. If /etc/X11/default-display-manager does not exist at all, I think it should not start up if lightdm is also present.
