ASUS Keyboard Backlight

Need help on G51jx

Asked by Csala Tamás on 2012-12-29

Hello!

I've installed your ppa on my G51JX on Ubuntu 12.10, but i can't get it working. Should it generate an executable file somewhere, in which i can adjust the kbd backlight brightness, or is it a driver that should work by itself after installing?

Thanks in advance!

Hello

ASUS Keyboard Backlight should by itself (but I haven't tested on Ubuntu 12.10).

Can you try the following commands:

    /etc/acpi/asus-kbd-backlight.py down # Lighter
    /etc/acpi/asus-kbd-backlight.py up # Darker/turn off

If those commands does not work, can you tel me if the following files exist?

    * /sys/devices/platform/asus_laptop/leds/asus::kbd_backlight/brightness
    * /sys/devices/platform/asus_laptop/leds/asus::kbd_backlight/max_brightness

Regards,

Hum... I made a mistake:

"/etc/acpi/asus-kbd-backlight.py down" will make the backlight darker (or turn it off), and "/etc/acpi/asus-kbd-backlight.py up" will turn it on or make it lighter...

Thanks for the fast reply!

The brightness and brightnessmax files exist, yet it still doesn't work properly. The brightness up and brightness down buttons do work, however, the minimal brightness it can reach is 130 (medium bright) and the max brightness is 131 (high brightness). And i want to turn it off...

calling "$ /etc/acpi/asus-kbd-backlight.py down"

results this:

(asus-kbd-backlight.py:3387): libnotify-WARNING **: you must call notify_init() before showing
**
libnotify:ERROR:notification.c:568:notify_notification_show: code should not be reached
Aborted

i tried useing pynotify.init("asus-kbd-backlight") but it still didn't work.

By the way thx to your help, now i can manually turn the light off with setting the value in the brightness file 0, so i actually got what i wanted :)

in fact the script must be lunched as root, because it write numbers in the brightness file...
