I have a kubuntu 12.04 system to which I added gnome (unity) but I'm now wanting to remove gnome as I don't think I'll ever use it. doing apt-get remove ubuntu-desktop doesn't remove the packages, so how can I safely remove all the gnome components? I don't really want to do a clean install if I can avoid it.
I suggest , if you want to remove gnome, unity and ubuntu-desktop, try the following commands.
I would also suggest you to run this last command just to be on the safe side, if any kde applications get removed, it will be installed back.
