About a month ago, had a small problem in 12.04. Crashed it, trying to fix it. (Do not remember what problem was, or what I did to crash computer). When I booted up, had no Unity. Ok, I was tired of Unity, and thought I wanted Classic. About a week and a half ago, I decided to go back to Unity, did not happen. Nothing I did, would get Unity to work right. The best was to use “unity –replace”. But on each boot, I had to give that command again. I have searched for a solution on the internet in many places. I made sure in CompizConfig Settings that Ubuntu Unity Plugin is checked, and Gnome Compatibly unchecked. Have had to change two times. Using “unity –replace” in terminal always has a process running. There are 41 pages in terminal now. I have looked up many of the errors, warnings, and no such interface. Have tried many fixes, no luck. There are bugs for many single line warning, but not many fixes. Probably some simple something, I am so frustrated, I can't see it. Will give some of terminal information. If you need all 41 pages, just ask.
