[Partially Solved] Gateway with x3100 Brightness Control

[jesusfreak198989]

UPDATE

I have been able to get brightness control by editing the dsdt file. I will post how I did this later. The new problem though is, even though I do get brightness control, It is uneven. The highest three are useable, the next two, the screen is unevenly lit. The rest all give a dark screen. I am unsure if anyone knows how to fix it. I'm not sure if this can be fixed in the dsdt file.

 

Search for the backlight section in the attached dsdt file, and copy it into the same section of yours. Then compile it.

 

 

I have brightness control when I boot the Install DVD (ideneb 10.5.6). I also have control when during boot, but lose it halfway through. I was wondering if anyone had a fix on this yet. I've been searching the forums with little luck, but I'm most likely just being blind.

 

Thanks in Advance

 

EDIT: I don't want shader software, I want to do this to increase my battery life.

I can't believe no one reply to this thread. I would like to try this out on my lenovo x61 tablet .

 

I believe what he was saying is to add this in the dsdt

 

Device (PNLF) ///Fixed

{

Name (_HID, EisaId ("APP0002"))

Name (_CID, "backlight")

Name (_UID, 0x0A)

Name (_STA, 0x0B)

}

 

But, how to I add this in my DSDT? Can someone help?

my osx86 side crashed, so I'm no longer able to help with this. Sorry all. Even so, this is all I am able to do, I just pieced it together from what i found on other threads. Hope someone else can pick up on this.
