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)... % uname -a Linux G75VX 3.13.0-40-generic #69-Ubuntu SMP Thu Nov 13 17:53:56 UTC 2014 x86_64 x86_64 x86_64 GNU/Linux % sudo lspci -v| sed -ne '/NVIDIA/,/^$/ { p; }' 01:00.0 VGA compatible controller: NVIDIA Corporation GK104M [GeForce GTX 670MX] (rev a1) (prog-if 00 [VGA controller]) Subsystem: ASUSTeK Computer Inc.

Ubuntu 13.10 2. N: Unable to locate package nvidia-graphics-drivers-319 3. I expected that when I changed the brightness level for my laptop monitor that the brightness would also change. 4. Instead, the brightness always stays at 100% I have tried every configuration of grub that I have seen online or been asked to try on freenode.net #ubuntu by 3 different people. Nothing seems to fix this problem. The file for the brightness is always updated but it is like the driver never tells the hardware to change the brightness. I have tried Tried : acpi_backlight=vendor pcie_aspm=force acpi_osi='!Windows 2012' Option "RegistryDwords" "EnableBrightnessControl=1" echo 50 > /sys/class/backlight/acpi_video0/brightness echo 50 > /sys/class/backlight/acpi_video1/brightness echo 50 > /sys/class/backlight/asus/brightness nothing seems to work (the files are of course updated but the monitor rests at 100% brightness) I have also tried the XOrg-server and nvidia-304 drivers. They all have the same result, nothing.
