First of all, thank you Blackch for the dsdt file so I got my brightness working. (I have a HP550, X3100 2A12)
With all the last kext (1.5.36), my display got dimmed half part darker as the others.
So I installed the FB.kext version 1.5.18 as I read it didn't give the invalid display error, but I was stucked at a blue screen, and with the
But my brightness control is ok, without the half part darker and works totally, well I have to use the function flip prefpane.
The only thing is that my card is now seen as a gma950 but it's not important.
thanks for the tip, my brightness is working now, have you managed to find a fix to the issue of display waking up totally unlight?
Also, can someone help me with the audio drivers, only speaker output working at the moment, i cant get headphone jack to work.
