There is some overlay option for the mga driver iirc, look for it for Linux the use of the (binary only) mga_hal driver was recommended/required for the matrox g450, it might be only for tv-out though, have a look at matrox.com/mga i've you'd need the mga_hal driver, the only solution would be to ask matrox for a freebsd one ;) To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-questions" in the body of the message
