I am new to Ubuntu and I felt like seeing if Quake Live would work. After choosing a match, I would be able to play. After a bit though the screen will freeze and then turn black and then go back to being normal. This happens regularly when playing even if I go full-screen. I first tried updating and nothing worked, then I stumbled on this forum http://ubuntuforums.org/showthread.php?t=1631301. I tried doing what was said there but that did not work at all. Is there something that I am missing?
