Graphics drivers are near the top of my list of issues I've had with Ubuntu. I've been using Linux for well over 20 years and Ubuntu (and to a large degree, other Debian derivatives) is just such a pain in the ass to install and configure. It is superficially a good UX in the sense that if you can somehow manage to stay on the happy path, it's smooth, but go an inch off of that and you're in for a world of pain.
