[Bug 931614] Re: ASUS backlit keys buttons don't work

[Felipe 'chronos' Prenholato]

It works but not fully. Something is changing
/sys/class/leds/asus::kbd_backlight/brightness after script.

See my test with a modified asus-keyboard-backlight.sh

root at felipe-G51JX:~# echo 0 > /sys/class/leds/asus\:\:kbd_backlight/brightness 
root at felipe-G51JX:~# /etc/acpi/asus-keyboard-backlight.sh up
ORIGINAL VALUE: 0
up
NEW VALUE: 1
File value after echo ...0
File value after 1 second ...129
File value after 2 seconds ...129
root at felipe-G51JX:~# /etc/acpi/asus-keyboard-backlight.sh up
ORIGINAL VALUE: 129
up
NEW VALUE: 3
File value after echo ...129
File value after 1 second ...131
File value after 2 seconds ...131
root at felipe-G51JX:~# /etc/acpi/asus-keyboard-backlight.sh down
ORIGINAL VALUE: 131
down
NEW VALUE: 3
File value after echo ...131
File value after 1 second ...131
File value after 2 seconds ...131
root at felipe-G51JX:~#

Nothing appear in syslog about it... So it is really weird ...

How I can collect more evidences?

Title:
  ASUS backlit keys buttons don't work

Status in “acpi-support” package in Ubuntu:
  Fix Released

Bug description:
  Ubuntu 11.10
  acpi-support 0.138
  ASUS G73jh

  The ASUS backlit key brightness up/down buttons do not have any acpi
  events/scripts assigned. The buttons trigger the following acpi
  events:

  up:
  hotkey ATKD 000000c4
  down:
  hotkey ATKD 000000c5

  I have attached a potential patch that works on my computer.
