Comment 19 for bug 855556

The merge proposal I submitted above (https://code.launchpad.net/~achiang/ubuntu/quantal/casper/bug-855556/+merge/106476) is a minimal fix to allow shutdown/restart to work from the Unity greeter during a live session.

I don't think it fixes the general case mpt is talking about in the original description, but my patch is a small step in the right direction.
