A mini tool written in C that changes the laptop backlight without using the RandR extension.
Currently, the program is hardcoded with amdgpu configurations. This program mimics the functionality of Xbacklight yet eliminates the X server overhead by directly changeing the value in /sys/class/amdgpu_bl0/backlight. Any constructive feedback on the code itself and platform compatibility is welcome and appreciated.
To install the program, simply input the commands:
$ make
$ sudo make install
To run the program, input the following command:
$ backlight_c [OPTION] [VALUE]
The options include inc and dec that respectively increases or decreases the brightness by the indicated value.
