Dark LCD screen on my VAIO!
 

Hi!!!
I have a Sony VAIO NV200 with Mandrake 9.2 installed on it.
I have a problem with the LCD since the screen is viewable but it's just too dark.
It's hurting my eyes.
Is there a program to brighten the screen just like in Windows and sony you have the key combination to iluminate the display more?

It's just too dark and bad for my eyes. I can work for a while but my eyes start bothering me.

Any suggestions?
