I had the exact same problem. I even had to reinstall ubuntu natty and work my way around to restore my desktop. I don know if it's related but the problem for me started when I activated a plugin in the CCSM to manage support for JPEG images.
Unity 2D worked fairly OK but with a few errors as well. In Unity 3D the top panel was frozen with the Menu titles, the launcher was gone, i couldn't use the dash or launch any application. The only one working was "Natilius" but when I wanted to open a file nothing happened.
