I'm running with a Radeon HD 6400M, and 13.04 seems to really not like the updated graphics drivers (or at least, that's the conclusion I've come to). After installing them I had exactly the same issue.

For me, the following worked:

sudo apt-get purge fglrx

followed by (possibly after a reboot, I can't quite remember. Probably do one just to be sure)

gsettings reset org.compiz.core:/org/compiz/profiles/unity/plugins/core/ active-plugins

The latter command seemed to take quite a long time to run, but once it had everything worked fine thereafter. Hope this helps.

You have to reboot after installing or removing the proprietary drivers (ati and nvidia) as they are loaded in the initrd – bodhi.zazen May 15 '13 at 17:47
