Upgrade from 11.04 to 11.10 failed. Reinstalled 11.10 without formatting. Appears that config files in /home are breaking Unity (because it runs fine from a live CD). Cannot run 'unity --reset' as the graphics corrupt, the mouse freezes and it appears the keyboard is frozen as well. How can I repair this from recovery mode?

This question has been asked before and already has an answer. If those answers do not fully address your question, please ask a new question.
I had the same problem. I solved it by doing similar steps to the comment by @jrg. If you are wary of deleting too many things, you can try deleting some of the Gnome settings files at a time.
