You can crash your Unity desktop on Ubuntu 11.04 when trying to enable desktop cube with Compiz. When this happens, the items on your desktop may become unresponsive. Hopefully, you can still log out of your user so you can change the login session to safe mode. If you cannot even do that, then try ctrl+alt+2 so you can be at a console prompt. Here you can login as a user and then do startx command to boot up the graphical login screen so you can change to safe mode session. If all is failed, try do ctrl+alt+delete to restart your computer, and then get yourself into a safe mode session.
The whole point is to be inside a safe mode session! Within safe mode session, fire up a terminal. Inside a terminal, you can execute this command [unity --replace]. There are two short dashes before the replace parameter. Done? At this point you may see errors inside your terminal, these can be ignored. Just restart Ubuntu, and you will see a working desktop again.
Sometimes, even the changes you have altered for your desktop through the use of Compiz may retain, but isn’t this a good news? It certainly is, because you have got your Unity desktop to work again,and on the top of that happiness you now also acquiring the changes you made earlier to your Unity through Compiz. Have fun making your Unity desktop looks awesome!
