I've installed FC6 test 2 a couple of times. Each time the installation goes fine until I'm into the first run screens. My video card (Nvidia FX5200) is detected properly but before I see anything about the monitor (Benq G775), the screen goes blank. The display doesn't recover and a hard boot is the only way I can get the machine running again.
Not sure if this is the right place to post this info.
