I tried installing Arch on my laptop and couldn't get it to work, so I went with Ubuntu because it was easy. Haven't had any problems so far, except one: I simply cannot get good results plugging my laptop into projectors. Either I can't mirror screens at all, or if I can, I end up at a lowest-common-denominator resolution, usually less than 1024x768. It could really become a dealbreaker for me, because I need to give a lot of presentations in places with their own projectors (e.g. classrooms). Anybody know if there's a Linux distribution that can do whatever magic Windows and Apple do when plugged into a projector?
