    display brightness problems

    hi, im using a Sony Vaio laptop. and i recently (couple of months ago) installed linux in it. Everything works well, but i cant change my display brightness and it is very dim. And my laptop doesnt have any external/hardware btns to brighten up the screen. Oh, my current distro is SuSE 9.2 pro. Does anyone know how to change the brightness of the display through linux. (When i boot as windows, i can tweek it with the special "fn" keys, but couldnt install those in linux).

    Increase the sliders..

    thanx for answering (sorry for not replying soon enough)
    well I tried what you said, but its not quite it, it works like when you increase the brightness of a jpg in photoshop, but it doesnt actually increase the brightness of the screen. And the display also looses contrast.
    thnx anyways.

    My laptop has the "Fn" key. i can use Fn + Ctrl +F7 or F8 to change the brightness. Does your computer have anything like that. i'm using Fedora 3 and it still works.
