Do not control the brightness of the keys Fn

Hello!
Netbook Samsung NC110, q4os-1.6.2-i386 kernel 3.16.0-4-686-pae.
Do not control the brightness of the keys Fn.
What could be the problem?

Re: Do not control the brightness of the keys Fn

You need to research Samsung NC110 Backilight Control Debian Jessie

There are a number of solutions that involve altering the grub boot configuration.

If you are confident with that then OK - follow them but if not, you may get some success using xbacklight which you can install through synaptic
or

sudo apt-get install xbacklight
then type this xbacklight -set 50

there 50 stands for brightness range we can get it up to 100 from 0 .

You can also increase and decrease the brightness from present value to specified level.
If you want to increase to 10% from current value of brightness then you can do

xbacklight -inc 10
and to decrease 10% you can give this

xbacklight -dec 10

If xbacklight does not work you may get some success with xrandr:-

sudo xrandr --output LVDS --brightness 1.0

sudo xrandr --output LVDS1 --brightness 0.5       =  half brightness

xrandr -q will show the name of the display but should be LVDS on your machine.

Re: Do not control the brightness of the keys Fn

Brightness controlled by of the terminal

sudo setpci -s "00:02.0" F4.B=90

Found information on the forum volia.org "Linux On My Samsung" , but the repository is not working

http://ppa.launchpad.net/voria/ppa/ubuntu/dists/jessie/main/binary-i386/Packages  404  Not Found

Made this on the instructions, but the OS does not boot in graphical form. Remove in the terminal xorg.conf.d/20-intel.conf - the system boots fine.

anton@q4os-desktop:~$ xbacklight -inc 10
No outputs have backlight property

xrandr works.
How to control the Fn I did not understand.
