Hi all, i am beginning to go mad with not being able to get my Graphics to work properly on my Dell GX260 with an Intel GMA950 Onboard Graphics.


I can use the Framebuffer kext, However when i use VGA it always thinks its the Secondary Monitor, PC has SIngle DVI which allows 2 outputs.


I have my DSDT.aml file which compiles successfully i have applied the RTC fix and alls well. However when i apply the GMA950 patch i get the apple logo with the loading wheel. then it flickers and goes onto a grey screen. i made it play a MP3 file when it loads and it plays that so i know its booting.


If some kind soul could have a look at my DSDT file and could give me a hand it would be sincerely grateful

I cannot get my EFI string and when i install the Apple Integrated Display it thinks my Output is on a Secondary Monitor when i use VGA.

Very Annoying since EVRYTHING else works 100% :blush:

P.S, When i use DVI/HDMI it detect One Display Only, When i plug in VGA (I only have ONE DVI PORT) it thinks i am on a Secondary Display!


This is now my only fault ;)
