If it is not something you can enable in your BIOS, i.e. if this feature ne= eds OS support then you should do the following. Check if your window manager/desktop environment has an applet for this. If= it does, that will presumably take care of the details. If it doesn't you'll h= ave to figure it out yourself as indicated below. Use 'xrandr --prop|less' to see if your display supports the backlight property. If it doesn't you can forget about controlling the brightness AFA= IK and skip the rest of this post. Install the x11/xbacklight port. This should enable you to set the backlight level using the RandR extension, if your hardware supports it. Next you need to know if your keyboard setup actually detects the FN key. Start the xev program from a terminal window, and move your mouse poin= ter into the xev window. You'll see a lot of mouse events scrolling through the terminal window. Now press the Fn key, and see if it registers in the termi= nal window. If it doesn't you need to use other key combinations (like just the F6/F7 keys). Next you need to look at your window manager documentation how to link keypresses to executing commands, so that is calls e.g. 'xbacklight --inc 1= 0' and 'xbacklight --dec 10' when the right buttons are pressed. This might be called a 'key binding' or a 'hotkey'.
