Ubuntu desktop not working after adjusting effects on compiz config manager

I unable to disable the desktop or anything, but when I reboot, all I can see is the mouse and a dialog appear saying that compiz has crashed. The terminal (Ctrl+Alt+t) doesn't work, and neither control alternative delete to log out works. What can I do to restore everything?

Try this:

1. Press Control + Alt + F1 and log in.


2. In terminal run unity --reset.
