You’ve tried Ubuntu and didn’t like the GNOME? You want to install Kubuntu with KDE instead?
I’ve a good news for you! You don’t need a separate Kubuntu Disc to install Kubuntu, instead you can just install Kubuntu right from your default Ubuntu Disc provided that you’ve a fast internet connection.
What you need to do is install the “kubuntu-desktop” package from synaptic or console apt-get :
sudo apt-get install kubuntu-desktop
and Ubuntu will take care the rest. To use Kubuntu, you just need to log out from your Ubuntu GNOME desktop, and click the Options to change it to KDE, log-in again, and then you’ll be officially inside Kubuntu.
Have fun trying out this trick!
