Hassle-free CLI backlight utility/library for Linux

Description

blight is a hassle-free CLI utility to manage backlight on Linux; one that plays well with hybrid GPU configuration and proprietary drivers.

A lot of Linux backlight utilities often fail to detect the right backlight device to control in laptops that ship with Intel or Amd iGPUs and an Nvidia dGPU with proprietary drivers. This utility aims to solve that problem by prioritizing integrated graphic devices, followed by dedicated Nvdia GPU and ACPI kernel module. This means that you do not have to manually specify which device is currently active whenever you switch between your iGPU and dGPU using the MUX switch. Other than that, blight also implements the sweep functionality, which lets you change brightness in a smooth sweeping manner, rather than applying sudden jerky increments/decrements.
