Hello, list!
Lenovo Y450-3M laptop with:
01:00.0 VGA compatible controller: nVidia Corporation GT216 [GeForce
GT 240M] (rev a2)
Subsystem: Lenovo Device 38fd
Kernel driver in use: nvidia
Would you, please, to explain how to configure a system or edit
configuration files in order to bring laptop brightness funktional
keys (Fn+key) to thier normal work? It is impossible to adjust
brightness pressing Fn+UpArrow and Fn+DownArrow keys. The symbol of
brightness is displaying well, but no adjust actually happen.
Googling left me unsure about what I have to do to correct this issue.
There are mostly comments from Ubuntu users. I know Ubuntu is Debian
based but need to be understanding what I am doing with my system. If
you have a little time, please, help.
Thanks in advance!

The solution is to add a line into your /etc/X11/xorg.conf
On the “Device” section append the following line:
Option "RegistryDwords" "EnableBrightnessControl=1"
After that I have reboot the machine and ta-da: Fn keys serve well to
adjust a brightness.
I have found that solution at
http://www.andresclari.com/blog/enable-nvidia-brightness-control-in-ubuntu-10-04/
and believe it is harmless, easy to apply and rollback.
Thanks to one who made it first available to public and everyone who
disscuss that.
