No version of Apple HDA kext works, i found a voodoohda version wich works someway, but the sound always gets some delay after a while, for example when watching a movie... when paused and playing again its again sync a while...
i though maybe it can be solved by a clean dsdt...
Graphics do work perfect, when attaching an external screen with perfect accceleration, even cuda works perfect... only the internal screen does not work... i thought it could be possible to inject a special pin configuration or something.
What I know... I had the same problem with black display under linux... a combination of a bios and a display driver update made it work, so it has to have something to do with bios and dsdt stuff...
I already read this: http://tonycrapx86.blogspot.de/2010/01/advanced-dsdt-fixes-nvidia-graphics.html
but i can not try it because my dsdt wont compile because of errors i dont know how to fix (not enough skill)... so I hope somebody could patch my dsdt...
I agree that the trackpad shouldnt be patched in the dsdt...
thank you for your help so far!
