I'm running 12.04 - I installed kubuntu to try it out and realized that with all the bloatware applications that I didn't want it anymore - I was able to uninstall the kubuntu-desktop but there are still packages left over... How can I make sure I get rid of EVERYTHING Kubuntu installed - even the kde leftovers?

Here's some of what's left when I ran sudo apt-get autoremove kde then "tab" it displayed this:

kdeaccessibility kdepim-runtime kdeadmin
kde-runtime kde-baseapps kde-runtime-data kde-baseapps-bin kdesdk-dolphin-plugins kde-baseapps-data kde-style-oxygen kde-config-cron kdesudo kde-config-gtk kdeutils kde-config-touchpad kde-wallpapers kdegames-card-data kde-wallpapers-default kdegames-card-data-extra kde-window-manager kde-icons-mono
kde-window-manager-common kdelibs5-data kde-workspace kdelibs5-plugins kde-workspace-bin kdelibs-bin
kde-workspace-data kdemultimedia-kio-plugins
kde-workspace-data-extras kdenetwork
kde-workspace-kgreet-plugins kdenetwork-filesharing
kde-zeroconf kdepasswd kdf kdepim-kresources
kdm kdepimlibs-kio-plugins kdoctools

Those are all installed by kubuntu... correct? I just want to go back to my Ubuntu 12.04LTS with Gnome2-classic and without all the kubuntu extras.

I started it off by just removing unnecessary apps that came with kubuntu-full - then realized I didnt want the whole thing at all and uninstalled kubuntu-full but it still says I have these as well:

alex@griever:~$ sudo apt-get --purge remove kubuntu- kubuntu-debug-installer kubuntu-netbook-default-settings kubuntu-default-settings kubuntu-notification-helper kubuntu-firefox-installer kubuntu-web-shortcuts
