How do I activate the LED backlighting of a Devastator II keyboard?

Can anyone give this novice a Step-by-Step process that will automatically illuminate the LED backlighting of a Devastator II keyboard upon Start Up? I'm running Kali Linux. The keyboard's Instructions refer to the Scroll Lock key for toggling ON/OFF. Apparently, that's for a Windows OS as it has no effect. And, if there is a way to control the brightness of the backlight, that could be useful, as well. Thanks.

Have you googled? There are lots of hits on this topic.

Thanks, erik2282. I have Googled it, just not sure I completely understand the procedure(s).

power supply. it has to have one.

the procedure of that first link looks copy paste to me.

Code:

#!/bin/bash
FLAGS=$(xset -q | awk 'NR==2' | awk '{ print $10 }')
if [ "$FLAGS" = 00000000 ]; then
	xset led on
else
	xset led off
fi

then you'd have to put a line in your .xinitrc or somewhere file that will load the shell script upon login, or in a place your kernel will run it upon boot up. Just be sure you have xset installed.

By chance, would it be possible to get the backlight powered up BEFORE signing in on Kali, when I power up the pc?
