How to sync screen backlight with keyboard backlight?

Hello,

I just wanted to know if there are any possibilities to sync the screen backlight with the keyboard backlight, so when the screen turns off the keyboard backlight does also and when turning on both turns on again.
I am using a macbook 9,2 and to control the lights I use brightnessctl as xset does not work with apple hardware/keyboars.

Thanks

There's no DPMS event, you'd have to continuosly poll the state, https://www.x.org/releases/X11R7.7/doc/ … l#DPMSInfo or "xset q | grep 'Monitor is'" - neither is a great idea

What makes you believe asking that again will change anything about that?
There's no DPMS event, but you can poll the DPMS state (what will keep the CPU busy and drain your battery)
