A super simple script to enable the G73 notebook series keyboard backlight on GNU/Linux systems

Asus G73 Keyboard Backlight GNU/Linux Scripts

To enable the Fn + F3 and Fn + F4 shortcuts to work under linux and really manipulate the backlight brighntess on your Asus G73 series notebook, follow theese simple steps:

1. Clone this repository to your home directory (or wherever you want to, I'll do this example for ~/ for simplicity)

    cd
    git clone git://github.com/ktoso/g73-keyboard-backlight-sh.git g73
   

2. Make sure all scripts are marked executable:

    cd g73
    chmod +x *.sh
   

3. Take a look at these scripts to make sure you trust them, why? Because they'll need root access, without asking for the password . Now we'll add these scripts to allow sudoto run them without asking for any password:

    su -c 'visudo' # or 'sudo visudo' if you're a sudoer (on ubuntu etc)
   

There just add the following lines at the end of this file (or similar, with the script names etc). Of course, replace ktoso and /home/ktoso/ with your username and your home directory.

    ## allow running keyboard backlight scripts
    ktoso ALL=(ALL) NOPASSWD:/home/ktoso/g73/*

4. Now all that's left is to setup the key bindings for the scripts. If you're on KDE4, just go to System Settings -> Shortcuts and Gestures -> Custom Shortcuts and edit -> import... the file ~/g73/g73_keyboard.khotkeys which contains ready keybindings for these scripts. Now you may use Fn + F3 to make the keyboard backlight shine less, and the Fn + F4 combination to make it shine more.

   If you're on a GNOME or other windowing system, please follow the usual steps for them to add some own keybinding. What you want to bind is simply calling the ~/g73/g73_light_up.sh and ~/g73/g73_light_down.sh scrips - easy :-)

Hi Ktoso,

I get the following error when I run:

sudo ~/g73/light_up.sh
cat: /sys/class/leds/asus::kbd_backlight/brightness: No such file or directory
current light level:
[: 10: Illegal number:

It would be great to get this working! I’m on Ubuntu latest version
