I tried to install gnome3 using a ppa. It made a mess so I reinstalled my system. Now, for some reason, when I enter to the Ubuntu classic session, I get both unity and gnome running at the same time (all my gnome-panels + unity dashboard and menu).

I suppose there is some configuration wrong in my home directory, but I have no idea of what should I change to get only gnome.

Any idea of how can I fix this?

1) We will need Compiz Settings Manager.

You can install this from the Ubuntu Software Center or by clicking here (Compiz)

2) Open Compiz (Alt + F2 and type ccsm and hit Enter)

3) Go to Unity plugin and disable it.
