Dale,
   Sorry for top posting but I'm travelling and responding on my phone.

   I don't think this is you hardware and probably not KDE. It's possibly
some Gentoo-ish issue.

   To test and get a KDE config I would boot a Kubuntu flash drive and
choose the 'Try it's option which installs nothing. If the GUI stays up
then look at drivers and general config. I run Kubuntu on 5 machines, all
with different hardware, and I've never had a failure that I did cause.
I've installed Kubuntu on at least 20 machines over the last 6 or 7
machines and every one has booted first time.

   Give it a try. If it does fail then it's possibly something about your
hardware but if the machine works as well as you say then I would buy you a
cup of coffee if it's not Gentoo-bssed.

Good luck,
Mark
