Your BIOS also has to provide video control via ACPI. I feel nervous correcting jhb, but I think he had a metal mis-fire here. I believe that he meant to say "You have to use the acpi_video(4) driver (kldload acpi_video)". In my case, I have acpi_video_load="YES" in /boot/loader.conf (brining the ways to do this up to 3). -- R. Kevin Oberman, Network Engineer Energy Sciences Network (ESnet) Ernest O.
