Add Scroll Lock LED switching support.

FarkasLory · April 3, 2020 at 10:22 PM

Hello!

I have a Darksector USB keyboard connected to my RPi4 LibreELEC(9.2.1) mediabox. This keyboard blacklight is connected (by hardware) to scroll lock led. Therefore, I would like to switch the scroll Lock LED somehow. I have tried through:

echo 1 > /sys/class/input/input0/input0:scrolllock/brightness

but no avail(maybe the kernel miss some hooks).

There is no xset (as there is no X server in LibreElec)

There is a python command in evdev module, that can switch LED but it is not present in LibreELEC.

Please add support for led switch.

IIRC evdev is part of the system tools add-on. Install and log out/in from the SSH console for it to be available.

I have installed the system-tools package, but no evdev python module

Code

# python

Can you hint me, why

Code

echo 1 > /sys/class/input/input0/input0:scrolllock/brightness

does not work?
