Comment 8 for bug 1174278

I'm glad the report was helpful :)

For people looking for workarounds. If you lose Unity (the panel does not come up after logging in, and most key combinations don't work), what I have found is that sometimes starting a session while in low graphics mode will disable the Unity plugin. Invoking ccsm (by using the Terminal, which comes up with Alt+Ctrl+T), enabling Unity (it does not have a checkbox in the listed plugins, but you can click on it, then enable it by clicking the checkbox in the left column) and resolving conflicts seems to work.
