Package brightnessctl

Read and control device brightness

https://github.com/Hummer12007/brightnessctl

This program allows you read and control device brightness. Devices,
by default, include back-light and LEDs (searched for in corresponding
classes).

It can also preserve current brightness before applying the operation,
allowing for use cases like disabling back-light on lid close.
