Hi.
I did a kernel update (linux (3.9-1 -> 3.9-2)) and now I can no longer set my laptop's keyboard LEDs using asus-kbd-backlight.
$ asus-kbd-backlight max
cat: /sys/class/leds/asus::kbd_backlight/max_brightness: No such file or directory
cat: /sys/class/leds/asus::kbd_backlight/brightness: No such file or directory
Maybe the files' location has changed after the system update or the system no longer detects the LEDs.
Does anyone have an idea ?
Thanks.

What do you see in /sys/class/leds/ ? Also, this might be better placed in the [testing] section (I'm assuming you're running [testing] due to the 3.9.x kernels).
All the best,

$ ls /sys/class/leds/
ath9k-phy0
$ ls /sys/class/leds/ath9k-phy0
brightness device max_brightness power subsystem trigger uevent
$ cat /sys/class/leds/ath9k-phy0/*brightness

Changing /sys/class/leds/ath9k-phy0brightness does not seem to affect the keyboard's LEDs (nor the display).
My laptop is: ASUS N56VZ

Yes, I have [testing] repos enabled. I'll post this in testing section then.
Thanks.

No, don't repost. Ask the moderation team to move it.

"ath9k" is the driver for Atheros wireless devices.
But whether the Constitution really be one thing, or another, this much is certain - that it has either authorized such a government as we have had, or has been powerless to prevent it. In either case, it is unfit to exist.

Yes, I know. I'm using that one.
The folder for the asus kbd backlight is missing.

Same problem here after update to 3.9.2 (no testing repos).
# ls /sys/class/leds/
phy0-led
# ls /sys/class/leds/phy0-led

After digging a bit, the following workaround solves the problem for me:
1) Automatically load the asus-nb-wmi kernel module. This module provides the asus::kbd_backlight, but doesn't load automatically for some reason:
echo asus-nb-wmi > /etc/modules-load.d/asus-nb-wmi.conf
2) Change the path in /usr/bin/asus-kbd-backlight to "/sys/devices/platform/asus-nb-wmi/leds/asus::kbd_backlight".

kyak,
thank you a lot. It worked for me.
I'll mark this as solved.
