I've got a samsung chronos 7 laptop. It's got Intel HD 3000 onboard graphics and ATI 6490m dedicated. I don't even see the ATI in system profile but the Intel does, and i can get full resolution and acceleration with dual link patch. The problem i'm having is that the screen brightness is like 10x too bright. Would it be at all possible to set the maximum brightness of the screen using some sort of dsdt modification?
