Title:
  Toshiba Portege Z835-P330 Keyboard backlight cannot be toggled via
  Fn+Z

Status in “linux” package in Ubuntu:
  Incomplete

Bug description:
  I am running Kubuntu 12.10 on a toshiba Z835-P330 laptop. From within
  windows, the keyboard command "FN+Z" turns on and off the keyboard
  backlight (retrolight).  From within linux, the command does nothing.
  Nothing shows up in /var/log/syslog on press of FN+Z, but other FN
  combinations do show up. Mainline kernel 3.8-RC1 does not fix this
  bug.

  WORKAROUND: Setting the backlight in the bios to "always on" turns on
  the backlight always, which works, but is not ideal as I have to
  restart to turn on or off the backlight.

  Here is the output from xev:
