You have to use the acpi_video(4) driver (kldload acpi_device or 'device acpi_video'). Your BIOS also has to provide video control via ACPI. > Any suggestions welcome, and thanks Christopher for raising this! You can also try http://www.FreeBSD.org/~jhb/patches/dpms.patch (you'll need to either add 'device dpms' to your kernel config or build dpms.ko and kldload it). It is a committable version of the old DPMS patch that uses VESA DPMS to turn off the monitor on suspend and turn it back on on resume. -- John Baldwin
