Macbook console turn off display?

[monty0]

I just set up an old 2008 macbook to run FreeBSD 11 and netatalk so it can be my time machine server. I notice that the laptop screen is always on. Is there a way from the command line to turn it off? I have not installed any GUI. My google searches didn't turn up anything, maybe I'm using the wrong terminology?

Recent versions of FreeBSD have switched to vt(4) instead of sc(4). One of the features that's still missing from vt(4) is the screensaver.

Actually, would there be a way to have it boot up without turning on the display at all? I can already ssh in, I don't need any console access at the machine.

As it's a laptop, just close the lid?

Good idea, but unfortunately the display stays on when I close the lid. I'd like to save the power and not burn in the screen.

Ah, that's a shame. I was hoping the laptop would automatically switch off the screen. I don't have a MacBook to verify but found a Wiki page for it: https://wiki.freebsd.org/AppleMacbook. It's fairly old (made for FreeBSD 8) but should still give some valid pointers.

Maybe you can have a look at those SMC sysctl(8), maybe there's one to switch off the screen.
