The multiple card case is doomed to failure for the time being. I expect the issue that you are having booting with the radeon is that it is a hybrid setup. I forget the name of it, but it will use the intel chip when it doesn't need power and switch to the radeon when it does. If your bios has options to fully disable the intel chip and only use the radeon, then I suspect that you may have better luck. I've been told that DPs worked on console on radeons, though hot-plug support likely doesn't. When I asked the amd folks about it, they told me that all of the support should be in the X driver now, but I think you might need the driver from git. As for intel. You might get it to work if you updated the DDX (X driver) to the 2.9 series, but you will lose drm support since they dropped support for anything that doesn't have GEM. Who to bug? Well, that would likely be me, but my time is in very short supply right now and I don't actually have any DP hardware. robert. > Also, Robert, thank you for responding. > > > This is a Lenovo Thinkpad T500. > % uname -a > FreeBSD battered.mike-burns.com 8.0-STABLE FreeBSD 8.0-STABLE #2: > Thu Dec 24 22:22:54 EST 2009 > root@battered.mike-burns.com:/usr/obj/usr/src/sys/BATTERED amd64 > -- Robert Noland FreeBSD
