I broke my unity by using cairo dock PPA, how do I fix it?
I have recently installed Ubuntu 12.04. I had installed Cairo-Dock as well. My brother closed something in Cairo-Dock, He doesn't know what exactly he did as he is new to Ubuntu. After he did that, The Unity panel is completely missing. Even the launcher is missing. The Cairo-Dock panel is also missing.
How can I fix this?
