I'd like to write a daemon to change machdep.lidaction and the xrandr output as
an external monitor or power is attached/detached from my laptop. Is there a
way to detect those events from a C program?
Here is how I want the sleep state and output display to change based on
whether power is connected, an external monitor is attached, and the laptop is
open:
Power Mon Open | Sleep Display
--------------------------+------------------
x x x | awake both
x x | awake external
x x | awake laptop
x | asleep
x x | awake both
x | asleep
x | awake laptop
| asleep
