Further information: The issue appears to be that the external monitor
is disabled when GDM loads. The Ubuntu boot splash screen appears, but
when GDM starts, the external monitor is disabled.

If I log-in blindly, the external monitor is reactivated according to my
GNOME settings (in this case, mirror displays).

As a reminder, this wasn't a problem at all under 10.04; it started
immediately upon upgrade to 10.10 beta.

 POTENTIAL WORKAROUND =

The issue appears to be at least partially due to the fact that the per-
user monitor configuration (/home/user/.config/monitors.xml) is not
being installed systemwide. If I manually create /etc/gnome-settings-
daemon/xrandr/ and run gnome-display-settings-install-systemwide, the
issue is resolved.

This raises a few questions:

* Which package actually contains the root cause of the bug? It would
appear to not be GDM's fault. I'm afraid I don't know enough about how
Ubuntu is structured to find out for myself.

* What should be done upon install? The default, IMHO, should be to
mirror all displays by default, so that if a user is installing on a
laptop with a docking station, they don't loose their login display.
