I'm using Ubuntu 11.10 with Gnome 3. There are some applications that I don't use or need, for example Totem. When I click remove in the Software Center (or in Synaptic), it says "gnome-core" and/or "The gnome desktop environment - essential components" will be removed as well.
I removed these applications about a month ago by ignoring the prompts and once I restarted, Ubuntu would not load and would simply sit there at the loading screen. I'm not sure if removing gnome-core caused this issue, but I really want to remove some of these applications.
What is gnome-core and how do I know what essential components are going to be removed? Should I go forth with removing them anyways?
