How to control the back light of Linux based pc. I am not having any hotkey setup for the same. I am looking for a nice brightness controller thing which is not working well. I am unable to use the function keys here. Which is not working well. I want some help here to get a simple tool through which I can manage and control the back light. I am quiet sure there are some of them available but I do not know to use them. Is there anyone who is using the the any kind of good app. I want keyword based control.
