Fix no Unity, no Launcher, no Dash in Ubuntu 12.10

I was installing Ubuntu 12.10 on my friend’s laptop the other day when i encountered this strange scenario. After the fresh install when I boot in to Ubuntu, there was no Unity, no side launcher, no dash, nothing. All it had was just the default wallpaper of Ubuntu 12.10:

Ubuntu Default Desktop Wallpaper

Ubuntu Desktop Without Unity

Clearly something was broken. I tried the good old technique to reset Unity and Compiz in Ubuntu, did not work. After looking for hours in forum, I came up with this awesome one liner solution.

Use Ctrl+Alt+T to open the terminal. Now use the following command in the terminal:

rm -rf .compiz-1

And that is it. No need to do anything else. You will have Unity back again. Cheers :)
