Hello, now it is possible for me to control the brightness via "System
Settings" -> Brightness and lock" -> "Brightness" slider!
But the fn button still not work (except once a time with the kernel
parameter "acpi_osi=" until to the next reboot).
Since Autum it works over die Brightness slider, but i don't no why...
maybe due to the newer nvidia driver (331.38 -> 331.113)...
