I've looked around for answers to this, but nothing I've found has been relevant, which seems a little weird but there you go. All I'd like to do is drive a second monitor via HDMI from a laptop. From Windows 7 on this laptop that works fine, of course; it's actually surprisingly nice. Thus I know the hardware is OK.
From another laptop I've got, one with an NVidia card, the NVidia settings app seems to do the trick (though it's clunky). However, this laptop I'm using has an Intel GPU, and I can't find any information about how to get it to recognize that a second display is available. Is it even possible to do this dynamically, or do I need to statically alter my "xorg.conf" to make the second screen available?
edit — sorry I should have noted that I run xfce.
