I wanted to see how 3D cube would look like with my 11.10, so I installed CCSM and turned on 3D cube and disabled expose (think that is what it is called). Then after that everything went sideways. I can get to the desktop but only see part of the top panel, no launcher, no indication area, just 'file' 'edit' 'view'…'help' alt+F2 does not work, the super key does not bring up the dash. Unity 2D works, but I rather Unity 3D. CCSM in 2D did not help. What can I do to restore Unity to before my fiddling with it? I tired ctrl+alt+F1 (to try some thing in terminal I saw for an answer to a question similar to mine) at the log in but i just got a black screen that was not responsive.
Thank you for your time and answers.
