I have a new Asus N76VZ laptop and I have several issues but the major for the moment is with the functional keys. I am linux beginner but here is what I've tried already, after reading other forums/thread.
1) Run xev - the fn + fX combinations are not detected
2) Run acpi_listen - when I type i see the output, for most of the combinations I get the same output "PNP0C14:01 000000ff 00000000" some of them(sleep/turn off monitor) are working so I can not see the result.

Any ideas how I can proceed from here?

Thanks in advance.
