I had to say something! =P
And @Rookie's comment about the popularity. You forgot ChromeOS, which is based off of Linux. Honestly, if they wanted to start using hardware accelerated graphics for their hardware they would have an obvious choice!
Nvidia seems to have it's stuff together when it comes to drivers, it's the one reason why I won't go with AMD until they have consecutive driver support for a long enough time to say it's reliable. I don't care what some of the people on here say, blaming devs for being biased towards Nvidia. It's no excuse, AMD should get it together. Though from what I've seen it's much better than what ATi was, at least you get drivers on a solid release schedule. =P
They have a KDE made CD, it gets everything up and running. If you use the experimental repo's afterwards you can get KDE to at least 4.5.1 (or is it 4.5.3? I might have borrowed Ubuntu stuff to get 4.5.3). You can also use my guide to build KDE, which if you follow it correctly and get all the dev packages it's really just building the modules in the right order. My kdesrc-buildrc has everything set up, you would just need dev packages. Unfortunately I didn't write down every dev package it asked me for, mainly because I already had a bunch so I didn't know if there were some that I had and people would need (didn't want complains about "you didn't say this"). Anyways, I've got KDE 4.6 up and running stable on Debian. =) I <3 my debian.Edited by mushroomboy - 2/27/11 at 9:00pm
