+ 1. install unity from precise-proposed
+ 2 make sure unity does not crash and works fine.

+ This error happened soon after I connected the HDMI cable which connects my
laptop to my TV screen.
Unity and compiz crashed: the top bar and side bar of unity disappeared,
and all open applications which were spread over multiple workspaces
were put on one workspace. However, everything also restarted and I lost
no work.
I've connected the HDMI cable before, and never had this error happen
before (although I've only been using 12.04 for three weeks).
I don't know if this is related, but at the exact moment the problem
occurred, I was moving my mouse over the indicators, trying to change
the volume settings.
