Yeah, I don't understand this well myself. I've only skimmed the surface of that code, but I should probably dive in to it soon to make sure I understand it. Ideally the drivers will be ported over to randr1.2 and the issue will be solved, but I'm not so optimistic on that one. - David Nusinow -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe".
