So there I was, messing around with an account and I really messed things up. I was trying out new themes, settings and whatnot, then I ran into trouble.
Simply put, if you mess things up, there is a way to get it back to the defaults (how it was when you created the user account).
This way you dont have to re-install anything and you will keep all personal data.
In your terminal, type
sudo rm -rf .gnome .gnome2 .gconf .gconfd .metacity
log back in
