I have ubuntu installed now and took screenshots while I was doing it. If you're going to make a guide I can give you links to these images or if not, I may go ahead and write a guide myself (prefer not to since I'm a noob and don't want to screw someone up). However I had no issues doing it, it was easy. Now on to Joseph's guide to get the miner going! :)
Update : Have miner running now, syncing up! Damn that took a while. But at least now I've learned a little something. :)
