Not working with ASUS N76VB and Xubuntu 13.04

[Slava Fomin II]

I've installed this program and rebooted the machine, but backlight controls (functional keys) are still not working.

My machine: ASUS N76VB
https://www.asus.com/Notebooks_Ultrabooks/N76VB/

My OS:
Xubuntu 13.04 (Raring Ringtail)

I will be glad to help you to fix this issue for this ultrabook, if you need any feedback from me just write me: andyidol [AT] gmail.com or Skype: fominslava.

Thanks and good luck!

Hello,

Does the following folder exists on your system `/sys/devices/platform/asus_laptop/` ?

if yes, what is its content?

[Slava Fomin II (slavafomin)]

No it doesn't.

Hum...

Asus Keyboard Backlight just add some scripts for linking the physical button and the ACPI functionality. If the folder does not exists, that mean that your hardware is not supported by the asus-laptop kernel module, and Asus Keyboard Backlight will not work :(

[Slava Fomin II (slavafomin)]

Oh, too bad (

What else i can do? Maybe we need to notice developers of kernel module or
someone else?

Can you check you have asus-wmi or asus-laptop module loaded in the kernel (using lsmod), if not, try to load them:

sudo modprobe asus-wmi
sudo modprobe asus-laptop

If you need more informations about this kernel module, you can go there:

http://acpi4asus.sourceforge.net/

[Slava Fomin II (slavafomin)]

Here's the command's output.

slava@intrepid:~$ sudo lsmod | grep asus
asus_nb_wmi 12854 0
asus_wmi 24213 1 asus_nb_wmi
sparse_keymap 13890 1 asus_wmi
wmi 19070 2 mxm_wmi,asus_wmi
video 19390 2 i915,asus_wmi

[Fabien LOISON (flozz)]

Hum,

What is the result of the following command ?

ls /sys/devices/platform/asus-nb-wmi

[Slava Fomin II (slavafomin)]

Sorry for waiting. Here it goes:

[Fabien LOISON (flozz)]

Hum, it seems to be cool :)

Can you try to replace

    MAX_BRIGHTNESS_FILE = "/sys/devices/platform/asus_laptop/leds/asus::kbd_backlight/max_brightness"
    BRIGHTNESS_FILE = "/sys/devices/platform/asus_laptop/leds/asus::kbd_backlight/brightness"

by

    MAX_BRIGHTNESS_FILE = "/sys/devices/platform/asus-nb-wmi/leds/asus::kbd_backlight/max_brightness"
    BRIGHTNESS_FILE = "/sys/devices/platform/asus-nb-wmi/leds/asus::kbd_backlight/brightness"

in "/etc/acpi/asus-kbd-backlight.py" (line 78-79).

Does it work better? If not, what is the content of the "/sys/devices/platform/asus_laptop/leds/" folder and sub folders?

[Slava Fomin II (slavafomin)]

I've made the changes:

[/etc/acpi/asus-kbd-backlight.py:78-82]
#MAX_BRIGHTNESS_FILE = "/sys/devices/platform/asus_laptop/leds/asus::kbd_backlight/max_brightness"
MAX_BRIGHTNESS_FILE = "/sys/devices/platform/asus-nb-wmi/leds/asus::kbd_backlight/max_brightness"

#BRIGHTNESS_FILE = "/sys/devices/platform/asus_laptop/leds/asus::kbd_backlight/brightness"
BRIGHTNESS_FILE = "/sys/devices/platform/asus-nb-wmi/leds/asus::kbd_backlight/brightness"

And rebooted the Ultrabook, but backlight keys (FN+F3, FN+F4) are not working.

BUT when i do:
root@intrepid:~# echo 3 > /sys/devices/platform/asus-nb-wmi/leds/asus::kbd_backlight/brightness
Backlight level is changing.

[Slava Fomin II (slavafomin)]

There is no such directory:
/sys/devices/platform/asus_laptop/leds/

but if you've meant:
/sys/devices/platform/asus-nb-wmi/leds/

Here it goes:

slava@intrepid:~$ find /sys/devices/platform/asus-nb-wmi/leds/ -print
/sys/devices/platform/asus-nb-wmi/leds/
/sys/devices/platform/asus-nb-wmi/leds/asus::kbd_backlight

[Fabien LOISON (flozz)]

Ok for the files :)

The only thing missing is the binding with the physical key... Please run the "acpi_listen" command and then press the button(s) that control the backlight and give me the output.

If nothing appear in the terminal when you press the buttons, stop acpid (sudo service acpid stop)and try again.

[Slava Fomin II (slavafomin)]

When running acpi_listen - no messages generated when i press backlight keys.

After i stop acpid service, acpi_listen can't run:
acpi_listen: can't open socket /var/run/acpid.socket: Connection refused

[Fabien LOISON (flozz)]

Hello,

It seems your backlight keys are not recognized by acpid... You can try to bind an other key on the python script :(

Regards,

[Slava Fomin II (slavafomin)]

And how to make ACPID recognize them?

I don't know how to make those keys recognized. I think you should ask this question to the asus-acpi developers. Alternatively you can bind an other key combination for this functionality.
