Title:
  There are no LCD backlight brightness function and OSD with Fn hot
  keys under Ubuntu 13.10.

Status in “linux” package in Ubuntu:
  Confirmed

Bug description:
  Steps to reproduce :

  #1. Install Ubuntu 13.10 x64
  #2. Change OS indication.
  $ sudo gedit /etc/default/grub
  Find
     GRUB_CMDLINE_LINUX_DEFAULT="quiet splash"
  Change to
     GRUB_CMDLINE_LINUX_DEFAULT="quiet splash acpi_os_name=Linux acpi_osi="
  $ sudo update-grub
  (Reboot)
  #3.Press hot key Fn+F8 or Fn+F9.

  More information :

  Our BIOS engineer had already checked the ACPI ASL code and all the necessary event notifications are normally notified as expected while Fn hot key pressed. Butthis issue is still there. We think there is no Intel graphics driver in Ubuntu 13.10.That's why we need it.
  There is no problem for all our Shark Bay models with the same ASL event notification under Ubuntu 13.10.
