While trying some compiz plugins, my Unity suddenly stopped working. Making me lose acess to my Dock, luncher, ETC (Can still access desktop). I am using Gnome3 at the moment, but i really miss Unity.
Try disabling the plugins that caused unity to crash. For me, unity's crashing (there's a lot of it, check the bugtracker) made me switch to GNOME 3. – hnasaratNov 11 '12 at 2:57
I actually found something on internet, a little program, that made compiz restart all of it's component related to unity well being. But thanks for sharing. – PlamZNov 11 '12 at 3:06
