Keyboard backlight not working on an Asus N56V
For N56V and N76V, you need :
- a 3.5 kernel (from quantal)
- to get the subwoofer
- I add on /etc/modprobe.d/alsa-base.conf this line: options snd-hda-intel model=asus-mode4
- reboot and select 2.1 output in audio pref
- to get the fn keys + keyboard backlight
- install asus-wmi-dkms_0.2_all.deb.gz package (from http://ubuntuforums.org/showpost.php?p=12057336&postcount=49)
- reboot
- to get the GeForce (when you want)
- install bumblebee and driver from x-swat repository
- to get the Ethernet
- build/install alx module (http://www.linuxfoundation.org/collaborate/workgroups/networking/alx)
Only thing that works for me is echoing like this:
echo 1 > /sys/class/leds/asus::kbd_backlight/brightness
Keyboard light hotkey (Fn + F3 and F4) rarely work on an Asus G60J
I bought an Asus N56VM laptop recently and sent the company an email concerning the following problem: Do not know how to turn on the keyboard backlight.
The following answer (edited) from Asus solved my problem:
- Go to Control Panel to uninstall the ATK package.
- Download and reinstall the ATKACPI driver and hotkey-related utilities. Here's the link.
- Download and reinstall the KB Filter Driver. Here's the link.
- Use FN+F3/FN+F4 to adjust the backlight of the keyboard for a try.
