Hi,
I have tried to make the Fn keys work for Asus N750JV and managed to get all of them, except brightness. WIFi (Fn+F2) was fixed by adding acpi_osi="!Windows 2012", but I can't get the brightness key to work by adding acpi_backlight=vendor. My kernel is version is 3.11. Is there anything I can do?
Thanks,
Paul

Is such keys recognize (xev)?
A part from the keys, is brightness management working? If so you'd just add a keybind in your wm.
If doesn't, you'd try the following kernel parameters, alone or in various combinations:
acpi_osi="!Windows 2012"
acpi_osi="!Windows 2009"
acpi_osi="!Windows 2006"
acpi_osi=Linux
acpi_backlight=vendor
acpi_backlight=legacy
Then you'd set a systemd's tmpfiles. For example:
w /path/to/the/brightness/file 0664 root users - brightnessValue
And then in X you'd use app like xbacklight and also a simple
echo "brightnessValue" > /path/to/the/brightness/file
The path to the brightness file would be something like
/sys/class/backlight/
With intel I have
/sys/class/backlight/intel_backlight/brightness
And to find max value for brightness
/sys/class/backlight/intel_backlight/max_brightness
Hope that help.
