Bug Description

During a maverick->natty upgrade I got a debconf prompt about having to manually restart gdm. During the upgrade gdm was not running. This is a pretty unusual situation so not a big deal and mostly cosmetic (and the upgrade did not fail or anything).

Attached a screenshot from the VM.

yes, gdm is handled specially in the service restarting; we call 'reload' instead of 'restart', since this is how we signal gdm to reload libraries without crashing currently open sessions. So if the service isn't running, 'reload' fails; we should fix the script to check for a running service first.
