Kubuntu/KDE Uninstall
To uninstall Kubuntu Satanic Edition, it makes sense to de-select the various themes before removing the packages. Here's what to do:
Remove the wallpaper (Right-click the desktop and select "Configure Desktop")
Reset the KDE theme (/etc/kde3/kdm/kdmrc):
Theme=/usr/share/apps/kdm/themes/kubuntu
Reset Ksplash (System Settings->Look & Feel->Splash Screen)
Reset the KDM background (/etc/kde3/kdm/backgroundrc):
Wallpaper=/usr/share/wallpapers/kubuntu-wallpaper.png
Removing the Packages
sudo apt-get remove \ kubuntu-satanic \ kubuntu-satanic-wide \ satanic-wallpapers \ satanic-wallpapers-wide \ usplash-theme-satanic \ satanic-kde-themes
Notes
Removing the usplash pakage should restore the default usplash artwork for your system. If you have problems with this, such as the Satanic splash remaining or a blank screen during bootup, just run the following commands to select your desired usplash artwork:
sudo update-alternatives --config usplash-artwork.so (select the usplash you want) sudo update-initramfs -u
