I'm on Maverick and every once in a while unity crashes and restarts. Which is perfectly acceptable since it doesn't happen to often and I assume there's some bug they are working on for the next version. Though once in a while it crashes to some sort of horrible looking graphics which reminds me of ugly looking Java applications.
Is there some way I can restart unity with the real graphics?
Restarting X isn't technically rebooting (but it might as well be), it solved the graphics but since you get into an empty window it wasn't really what I wanted:
sudo /etc/init.d/gdm restart
