Please follow the steps in /usr/share/doc/udev/README.keymap.txt.gz to
check whether the keymap needs to be updated, and the right scan
code/keycode mapping. Thanks!

Title:
  "CPU fan control not available"  on Samsung 900X3c

Status in “udev” package in Ubuntu:
  Incomplete

Bug description:
  Using Fn+F11 shows the message "CPU fan control not available" and the
  current temperature. In 12.10 multiple pressing of these button
  switches from silent to normal and I think something like turbo/heavy
  use resulting in increasing usage of the fan.

  In Ubuntu 13.04 this function is gone. In addition the keyboard back-
  light buttons (Fn+F9 and Fn+F10) invoke the message but I can not
  modify the brightness. It is always at max. More strange this is
  independent whether the light is on or off.

  Ubunut 13.04
  3.8.0-19-generic #29-Ubuntu SMP Wed Apr 17 18:16:28 UTC 2013 x86_64 x86_64 x86_64 GNU/Linux
