I am pretty new to 11.10. I was trying out some settings to operate the desktop in 3d cube mode that's when the unity bar, side bar disappeared. I have tried quite a few things to get it up and running but now even my terminal does not work with the shortcuts on the desktop.
Can someone please help me with what I need to do to resolve this conflict? Where do I begin?
compiz --replace
and press ENTER. Now restart your computer. It works? – Lucio Aug 20 '12 at 00:35
