[Bug 533690] [NEW] ASUS G60J keyboard backlight brightness hotkeys don't work

[C.J. Adams-Collier]

Public bug reported:

The following troubleshooting indicates that an ACPI events fired by the
keyboard backlight up/down hotkeys are not being propagated as an input
events.


https://wiki.ubuntu.com/Hotkeys/Troubleshooting

See section 6a:

run xev to test whether a keypress event is seen:
xev | sed -n 's/^.*state \([0-9].*\), keycode *\([0-9]\+\) *\(.*\), .*$/keycode \2 = \3, state = \1/p'

if the key code is wrong, or >there is no keypress event<, or the key
only works once and then the desktop gets "stuck", exercise the "Fixing
broken keys" section in /usr/share/doc/udev/README.keymap.txt (Ubuntu
9.10 and later).

  Find broken scan codes:
  sudo /lib/udev/keymap -i input/eventX

if >not found with keymap<, use >acpi_listen< to determine whether the
key is coming through as an ACPI event instead of a keypress

$ acpi_listen # 0xC4 = up, 0xC5 = down
hotkey ATKD 000000c4 00000011
hotkey ATKD 000000c5 00000011


if >there is an ACPI event but no keypress<, this is a bug in the kernel (ubuntu-bug linux) for not translating the ACPI event to an input event.
