On my 8 year old ECS iBuddie4, which I'm typing on, I could not get
either Kubuntu or Ubuntu, both Lucid, to install. I tried Xubuntu and
much to my surprise it installed and worked perfectly.

Since I really wanted Kubuntu I thought I'd try to install
Kubuntu-destop from the repositories and much to my surprise and
delight it installed without a hitch and works perfectly. I may remove
some of the remnants of Xubuntu, but they really aren't that many or
in the way.
