brightnessctl VS light

Make sure you've the correct /usr/lib/udev/rules.d rule.

brightnessctl that works well! https://github.com/Hummer12007/brightnessctl

Tip: brightnessctl is a program that does the same thing and doesn't need udev rules.

try brightnessctl (present in official repos)

I think I used this one, seemed to work for me

The problem was with udev rules. It was not there for some reason

brightnessctl should be used without root permisions. Check how you can do it th the README: https://github.com/Hummer12007/brightnessctl. Depending on how you installed the package the udev rules could be already installed but you also need your user in the video group.

brightnessctl - This program allows you to read and control device brightness.

I'm using wayland/hyprland and using light from https://github.com/haikarainen/light to control the lighting.

Try light. The repo's been archived, but still works as of today.

Copy code sudo apt install light For Fedora-based systems, you might have to build and install it from the source. You can find the instructions on the official GitHub page: https://github.com/haikarainen/light

For brightness, I use [light](https://github.com/haikarainen/light) and these key binds:

I found this which seems helpful although I don't have enough experience with writing Linux modules https://github.com/haikarainen/light/blob/master/DOCUMENTATION.md

I don't know what is torch in this case but controlling leds can be done with a tool called light: https://github.com/haikarainen/light

I am trying to make my Thinkpad's keyboard led's to work with the keybinds in dwm. I am using this program to control the led: https://github.com/haikarainen/light It works when using manually, but the set command requires number '100' to turn led on and number '0' to switch it off.

My Fn keys are bound to light, so I can't say for sure it would work in all environments.
