Thanx for this samsung+linux forum I think it's a really great idea!

I can change brightness when GRUB is showing the system list but when Linux Mint (my system) loads the fn+cursor combination doesn't work.
The only way to change brightness is by terminal command
sudo setpci -s 00:02.0 F4.B=XX
where XX is the brightness value.
My current kernel is
