Unity doesn't load, no Launcher, no Dash appears

What I did:

In a fresh setup of 11.10, I used compizconfig-settings-manager as explained in this question to change the icon size of the Unity launcher.

What happened:

As soon as I did this, the application froze and the launcher disappeared. I thought, well, maybe Unity crashed, so I logged out with Ctrl-Alt-Del, and logged in again.

Unity still does not appear anymore. I am just left with my desktop background and Nautilus running. I can open a new Nautilus window, and browse my file system, but that's about it.

What works:

I can log into Unity 2D, only the "normal" Unity does not work.

So, how do I get Unity back? Is there any way to reset the configuration, or look for some more detailed error messages?

What I already tried:

• Starting a Terminal and running unity --reset. It's stuck at "Initializing session options … done", and nothing else happens.


• Starting a Terminal and running unity --replace. Same as above.


• From the 2D mode, calling unity --replace or -- reset. It hangs after "Starting unity-window-decorator", and if I abort the process, my keyboard input is disabled.
