I recently added cairo-dock which worked fine until I added a 2nd dock at the top left of the screen. Since then, my computer has consistently reported system errors. How do I get the unity launcher back? I've have clicked "remove" for the cairo dock in the software section; it tells me it is removed, but yet it remains. Feels a bit like "Hal" from 2001. Any suggestions?

If the software has indeed been removed then "log out" and back in. This should start a new session. If then you don't have the "Unity" ......Ctrl+Alt+F2 then log in and type this unity --replace now Ctrl+Alt+F7 and return to your desktop.
