http://askubuntu.com – I'm trying to use an 11.10 Live Cd to try out Ubuntu, but an error's preventing me from doing so. Whenever there's activity on the screen (move the mouse, click, etc.) the screen goes completely back for about 3 seconds or flickers. I can't even get the drivers for my monitor (which is an Acer x223w) off of my USB stick, which I thought might help. If anybody has any suggestions that'd be great. Thanks! (HowTos)
