Backlight LEDs don't work, scroll lock key

Hello, how is everything?

I recently installed Manjaro, and my keyboard backlight no longer works.

It is activated by the “Scroll Lock” key, in Ubuntu based distributions it has always worked.

I tried some solutions like:

xmodmap -e "add mod3 = Scroll_Lock"

xset led 3

But nothing worked. I use the ABNT 2 - Lenovo IBM Keymap

Do you know of a way to make this work?


You should start from here Keyboard backlight - ArchWiki and let us know where you get stuck.
