How to switch to KDE graphical interface in Ubuntu 8.10 Intrepid Ibex

The main difference between Ubuntu and Kubuntu is the graphical environment (Ubuntu uses Gnome as default, while Kubuntu uses KDE). Having two operating systems installed will ruin the fun because you will need to restart and so on, but the good part about those graphical environments is that you can have both of them installed and choose which one to use, while running only one operating system.

If you are using Ubuntu and wonder how to KDE looks like you can easily install it (using the tutorial at the bottom of the page).

NOTE: This method will install some open-source software which automatically comes with KDE/Gnome, this means you might end having two applications for the same task. (Example: 2 browsers, 2 instant messenger applications). But no problem! You can always use your Gnome applications in KDE and vice-versa and you can always remove applications from your system if you don't like them.
