If you are using Linux on your Laptop then you have been using builtin brightness functionality which doesn't offer much but to increase and decrease brightness. Brightness Controller offers more functionality than builtin one, it is written in Python programming language and Pyside, it works with Pyton2 version.
It lets you control the brightness, Color temperature of the display and RGB as well. You can control all these values from 1% to 100%, apart from hardware brightness control which lets you control the brightness like 10% 20% 40% and so on. It should be mentioned that it changes the present brightness value set via hardware control of your monitor. For example, if you set your Monitor's brightness to 50% using hardware buttons, then that will be the 100% value in Brightness controller. It also supports arbitrary number of displays, further more you can save current configuration profile and load them as you need.
