I'm using a laptop. When I plug the charger into my laptop, screen brightness becomes 100%. After removing the charger, it decreases.
In Windows there are two options for brightness.
Why isn't there an option in elementary OS Freya - each for Plug and Unplug brightness?
How do I set it now?
My keys work but I have to readjust brightness every time when plug/unplug. I want dual option for brightness like this https://i.stack.imgur.com/9wWiY.png
and I want to know how to set custom brightness value for my laptop When I disconnect and connect the charger.
