Kubuntu recognizes the Fn + up/down but it only changes the brightness when it goes from 85% to 71% or viceversa. I want to know an easy way to change the screen brightness. I don't care if the method doesn't use the Fn key. I don't have installed the Nvidia drivers because kubuntu doesn't worked when I installed it and I had to reinstall kubuntu. I found this method but I don't know if ubuntu solutions work in kubuntu (let me know that too).
