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?
