I kinda got fed up with the poorly utilized top bar area of GNOME and decided to remove it in favor of Ubuntu’s former Unity desktop. To get it work properly I had to make sure GNOME was completely removed removed from my system as they share some settings. I also installed the proper Ambiance and Radiance themes were installed. I also reinstalled lightdm and removed gdm for my log in screen.
If you want a good take on why Unity just works check out Infinitely Galactic’s Vlog post on the subject.
Gnome is not bad, I like it, but Unity is superior. My thoughts
I have separate workflow issues with both. Unity has a better search and HUD while Gnome handles virtual desktops a little more efficiently.
