IMHO, Unity is just as productive and functional as Gnome Shell, and since for me, Gnome Shell looks a lot more stylish, I would like to replace Unity in Ubuntu 11.10 with Gnome Shell.
EDIT: Without a further thought, I opened the Ubuntu Software Center > searched "Gnome Shell" and installed it. And since I use auto-login, Ubuntu logs-me-into Unity.
To prevent that...
I want to uninstall Unity completely. How do I do that?
After doing the above, Gnome Shell loads by default right?
