DSDT on Toshiba P770

Recommended Posts

Hi all,


Sorry for my bad english, i'm french, but i will try to explain my problem.


I have a Toshiba P770, with HM65 chipset, HD3000 (0116) & Nvidia Optimus GT520M.


I can only boot with GraphicsEnabler=No & smbios.plist Macbookpro 8.1, and remove all Nvidia / HD3000 / AppleIntelHD* kext.


Then i have a 1280x800 resolution, with QE/CI but i have a lot of mouse lag, and my intel HD3000 is only 64Mo.


If i boot with HD3000 Kext (ML 10.8), i have 1600x900 screen (512 Mo), but screen is very big, and only have half screen.


is there a solution with DSDT ?


I have extract my DSDT with AIDA64 on Windows, rename into DSDT.aml, and put it in my Extra Folder, but no change.


Can i hope any help ? :)


Thank you a lot !

Chimera is already the lasted version.


Reading DSDT.aml OK, but same issues :(


But can only boot with GraphicsEnabler=No !


Without kext => 1280x800 laggy and 64 Mo

With kext => grey screen with mouse extra zoom


Test the laster FakeSMC but nothing :(


if i boot with GraphicsEnabler=Yes i have

Nvidia GeForce GT520m 0MB NVd9 [10de:1050] : : Pciroot(0x0)/pci(0x1,0x0)/pci(0x0,0x0)

 

Edit: smbios macbook pro 8.1 doesn't boot, only smbios macbook pro 8.3 (to correct my first post)


Edit2: I think that i must patch the DSDT to disable nvidia optimus :( because i can't disable it in the bios :( but how to, that is the question :)

Sorry, That method don't work. I can see people in the comment struggling as well.



sanjayrup,


Keep an eye on this thread. These people have successfully disabled GPU. I have asked them for help and attached the DSDT and SSDT.

2 ways to get the wife card working. Use a edited kext or add DSDT edits.

I have the same wifi card and i have managed to get it working with DSDT edits with the help of this forum.


Run IOReg and save it with no extension and attach it.
