How can I get back to Unity?
I did a ppa purge and now sort of have Unity back, but still have the GNOME boot screen, the font, the close button for windows on the right side. Also if I minimize an application, Xorg and the application have around 100% CPU usage.
I also tried
sudo apt-get install unity and
sudo apt-get dist-upgrade, but it's already up to date.
I have my home folder backed up with Déjà Dup, but I would like to avoid reinstalling and reconfiguring my whole system.
