Bug description:
  Toshiba satellite A660 backlight just never worked on ubuntu.

  Here is an outline of some of the LEDS in a toshiba

  http://i.imgur.com/l54s5CP.jpg

  When i press Fn+Z the ubuntu keyboard LED notification shows up,
  however nothing changes.

  so i navigated to

  /sys/devices/pci0000:00/0000:00:1c.4/0000:16:00.0/firmware_node/subsystem/devices/TOS1900:00/leds/toshiba::illumination/device/leds/toshiba::illumination

  found files

  brightness device max_brightness power subsystem trigger uevent

  when i changed the value in brightness from 0 to 1

  LED 1, 2, and 3 in the above picture turns on, and led 1 turns off
  when touch bad is off.

  However there is no keyboard backlight.upon boot the backboard
  backlight works while posting and shutdown when grub loads. When i
  disable acpi the keyboard backlight works however ill lose other
  functionalities like brightness.

  Any way to fix it?

  There is also another directory.

  /sys/devices/pci0000:00/0000:00:1c.4/0000:16:00.0/firmware_node/subsystem/devices/TOS1900:00/leds/toshiba::illumination/device/leds/toshiba::illumination/subsystem/mmc0::

  with files brightness device max_brightness power subsystem trigger uevent
  nothing happens when brightness value changes.

  #Problem also exists in older version of ubuntu, new kernel in 13.04
  does not solve the problems.

   xev shows a key being pressed and being mapped to kbdbacklight. A a notification that keyboard is being turned on appears when Fn+Z is pressed. Also unlike other manufactures toshiba doesn't have brightness on backlit keyboards, its either on or off or a timer.
