My Hackintosh runs reasonably well. I just got one annoying problem. I can't change the brightness of my screen.
If I try to use the Keys fn+f8 to adjust brightness my computer crashes. What makes things worse is, the brightness seems to go down on its own. After a few hours I have to boot into windows and adjust the brightness.

I've seen this tread http://www.insanelym...howtopic=101966 that recommends to use setpci. Does anybody know the prober setpci command to adjust brightness with an Nvidia Geforce 8400M GS or can recommend another solutions.

Hey dude just curious if you managed to get the ACPI backlight working more "officially", e.g. with Apple Brightness Bezel
