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.
