This question already has an answer here:

I'm a newbie in Ubuntu and so far it has worked really good, but there is one small problem, I can't control the brightness. The brightness control shows on the screen but it doesn't change anything, even if the control bar moves from left lo right, the brightness is always set to the maximum.

I have tried to follow a few tutorials without any success, I really don't know anything about using the terminal or anything at all about solving issues in Ubuntu. I need to be given instructions in step by step.
