Is there any way of turning off an iMac's LCD console backlight,
with OpenBSD 5.2 running on an iMac (2006)?
(The video card died so the machine is running as a server
in console mode, and I don't want the backlight to burn out.)
If this were a PowerPC Mac, OpenBSD/macppc could do it, with
wsconsctl -w display.backlight=0
but the iMac (2006) has an Intel Core 2 Duo.
I was able to use
wsconsctl display.kbdact=on
to blank the screen so to avoid burn-in, but the backlight is still lit.
If there's no current method, what would it take to port the
macppc solution to Intel Macs?
