You have been subscribed to a public bug:
This crash happened immediately after todays updates (4/12/2012) and rebooting.
100+ packages, notably to compiz and unity. I get to the login okay, then the
desktop tries to start.
Unity desktop never appears, then the background disappears, there is some
flickering,then just black screen.
After a while the apport box appears along with the background. Hence I report
this bug.
Going to forcibly shut down and reboot to see what happens.
