Hi all,

 

I have a thinkpad X300 which has an Intel X3100 graphics card. I cannot seem to get OSX (Snow Leopard) to allow me to control the screen brightness. Does anyone have any hacks for this? I have extracted my DSDT, and I use the Intel GMA X3100 drivers for full resolution options and a working card.

I added this to my DSDT:

 

	   Device (PNLF)	///Fixed
	{
		Name (_HID, EisaId ("APP0002"))
		Name (_CID, "backlight")
		Name (_UID, 0x0A)
		Name (_STA, 0x0B)
	}

 

... I added it right above Device (PCI0)

 

ScrLk and Pause are the keys for controlling it, and the slider shows up in Settings -> Display
