Days ago I was playing with Gnome 3 and Cinnamon and I decide after a few test to keep Cinnamon and remove Gnome. The problem is I don't know if it's secure to remove everything marked as installed under the group
GNOME Desktop => GNOME since I don't know if those packages are used in any other application or maybe by Cinnamon.
What's the best and secure way to remove Gnome 3 completely? What or how would you do that?
