How to light up back-lit keyboard?

Question

I recently got a backlit keyboard, and I LOVE to write late at night.

But I cannot for the life of me figure out how to light it up...It lights up when first plugged in, but nothing happens after that....

It is an 'XtremeIT' keyboard. There is a video of someone on Ubuntu who managed to activate it...

Answer 1

Did you try the script the youtube poster suggested in his own comments? Basically use xset to toggle the state of the led backlight.

#!/bin/bash
if [ -f /tmp/keyboard_light ]; then
xset -led 3 && rm /tmp/keyboard_light
else
xset led 3 && touch /tmp/keyboard_light
fi

(I would have made this a comment on your original question, but I don't have enough rep yet.)

Answer 2

What model is the keyboard? I have the old G15 and mine lights up fine. Usually the keyboard itself has a button to enable/dim/brighten the light.
