A simple script to change the backlight brightness value on laptops. Mostly made as a workaround for [this bug](https://bugzilla.kernel.org/show_bug.cgi?id=203905).
## Configuration
The only configurable variable is the backlight path. It defaults to `/sys/class/backlight/amdgpu_bl0`. You can change `BACKLIGHT_PATH` to point to the file path.

## Usage
