I thought I was clear, but I'm not always coherent when I communicate (apparently... just ask the missus :) ). The laptop is a compaq cq62 with a quad core phenom and a ATI 4200 Radeon mobility GPU, as well as 6300 GPU. The HTPC/desktop is a whitebox quad core phenom on a ASUS MB (not 100% sure which) with a NVidia onboard pcie GPU, and an ATI Radeon 3450. There could be yet another GPU on there, but I can't remember. That system is running 8.x FBSD (1 or 2- can't quite remember), and the laptop I'm installing 9.0-RC3 on, with the view to using freebsd-update to RELEASE, because of the lack of Atheros 9285 support in 8.x (tried for hours, just couldn't get the bird to fly :( ). From what I understand now, having been able assimilate what has been discussed here and through google, it seems there is a conflict when dealing with multiple onboard GPUs. What exactly is the issue with getting an arbiter for FreeBSD? Aside from time, naturally.
