4. Press the Y key on your keyboard and then Enter when asked for confirmation.
5. The download and installation of the KDE desktop will then begin.
6. When prompted to select the login manager, select kdm.
7. Once the installation has completed, restart your computer.
8. At the login screen, click the icon to the left of the textboxes, mouseover Session Type and select KDE.
