One issue I ran into was that metacity was not running, and it got
'deleted' from the session I was running (I had selected 'reflect
changes on logout').

Even after mesa got fixed (or if I ran with SELinux not enforcing), I
still had no 'metacity' functions since it was not running.

Manually starting metacity restored it to my 'session' from then on....
