The only thing I have found is if I do a sysctl hw.acpi.video.crt0.active=1 and then sysctl hw.acpi.video.lcd0.active=0 that turns off the display completely, but it is difficult to get it to turn back on, plus the video card is still active so there is no power saving. Am currently running 6.0-CURRENT, built today, but I find the same thing on 5.3, and 5.4 pre. Thanks in advance.
