mybl

Simple monitor brightness tool based on system files and independent from X11/Wayland

Install

To install this program you need a Nim compiler and the nimble package manager (which comes with Nim). The recommended method to install it is to use choosenim.

$ git clone ...
$ cd mybl
$ nimble install

Note

To change the required files the program needs appropriate file permissions. This could be done by a udev-rule for example.

Another way is to change the ownership of the binary to root and set the s-bit. The script rootify.sh does exactly this.

$ ./rootify.sh

Usage:

$ mybl -h
