buttcrap posted a topic in LaptopsI'm trying to disable my discrete graphics card and the consensus seems to be that it should be disabled through an SSDT, not necessarily in the DSDT itself. So I extracted my DSDT and SSDT's using Ubuntu, added the .aml extension and using maciASL I can't find the area the area that I need to turn off. All of my knowledge I have on this comes from the guides and forum posts I go over, I don't have any prior experience with DSDT's. Here is the most precise guide I can find on the subject, and it specifically states that it's for Radeon cards. Here's the issue: it says to look for \_SB.PCI0.PEG0.PEGP function. I don't have this function anywhere in my SSDT's; most of them look like they're for the processor. I do, however, have SB.PCI0/PEG0/PEGP in my DSDT but it's in subdirectories and not all on one line. I also can't find the _OFF or _ON methods that it states that it would have neither anywhere in my DSDT or in any of my SSDT's. I think that PEGP is definitely something to look at, but there doesn't seem to be anything there that I would need to go forward. Does anyone have any suggestions? I'm using Clover on Yosemite 10.10.5. This is an HP DV6t 6100 i7 + HD3000. My DSDT has already been modified a few times to get brightness, battery, etc.
Who have Intel HD3000 + AMD Radeon 6770M setup working under macOS? If yes then give suggestions about making it fully working. Loading VBIOS in Clover and Injecting Intel+ATI gets me till Login window where it freezes. I have extracted GPU rom. Patching VBIOS with it in Clover doesn't change anything. I assume it needs setting FrameBuffer. But I didn't read about that yet. I don't have time to read that till Winter. So I need help getting it done.
