I tried all this stuff.
Press Ctrl+Alt+F1 and log in. Install the jibby you'll need to configure the settings by running this:
sudo apt-get install compizconfig-settings-manager
Then run it. The first part tells the terminal which display you want it to load on (otherwise it won't have a clue).
export DISPLAY=:0 ccsm
Press Ctrl+Alt+F7 (or Ctrl+Alt+F8 sometimes) to get back to the graphical display where there should be a CompizConfig Settings Manager screen sitting there.
Find the Unity plugin. Enable it.
Everything should spring into life but if it doesn't, you might have to restart. You can do that by going back to TTY1 and running sudo reboot.
But none of it worked. I have uninstalled and reinstalled, but nothing. I also have checked to make sure the Unity plugin is enabled.
