I took a slightly different route. Turns out I can install Xubuntu right alongside Kubuntu and decide which I want when I start up. Best of all, it appears I might be able to use my preferred KDE applications in XFCE -- and I don't have to reload the computer at all.
I'm about 40% into the download phase of installation.
Excellent!
I went to hook up the scanner the other day to make some copies, and the computer couldn’t install from the CD. I had to download the driver from the website. It must have taken me an hour to get that thing up and running.
*sheesh*
