headbangerThis was originally intended for an Asus G73 laptop.  I have an Asus G55VW laptop, and it works great. (It requires the installation of 2 separate scripts!)  I didn’t even change the directory name.  (/home/jed/g73)  Scripts attached at bottom of post…
This is taken directly from the README file included with the g73 script;

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

        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 `sudo`to run them without asking for any password:

su -c ‘visudo’ # or ‘sudo visudo‘ if you’re a sudoer (on VSIDO etc)

Then, just add the following lines at the end of the sudoer file (or similar, with the script names etc). Of course, read more
