[nofearl]

I've a 2 gfx (Nvidia 9600 GT) and 4 monitors setup, and I've been using it since 10.6.x. With 10.8 GM, after (almost) every reboot/start the main display graphic card switches.

I've been using the following DSDT, properly setup with NVDA,Parent & NVDA,Child without any problems. I've also tried;

- Latest chameleon build, and a couple of older builds,
- Latest chimera, with and without DSDT code
- Enabling and disabling graphicsenabler for both bootloaders
- Switching BIOS setting to PCI/PEG/PEG2
- adding "@0,AAPL,boot-display"
- deleting both com.apple.windowserver files and restart
- removing cards and cleaning contacts (really!)

and a couple of other things I can't remember now, and 3-4 reinstalls. It still randomly switches main graphic card. I can't figure it out. Any help would be greatly appreciated!

Fix:

1. set DropSSDT NO, enabling it instantly brought back the problem
2. add

							   "@0,AAPL,boot-display",
								Buffer (0x04)
								{
									 0x01, 0x00, 0x00, 0x00
								},
								"@0,AAPL,primary-display",
								Buffer (0x04)
								{
									 0x00, 0x00, 0x00, 0x00
								},

to your first card.
3. Delete com.apple.windowserver.* files from /Library/Preferences and ~/Library/Preferences/byHost

cross your fingers and reboot.

Scratch that, still not working. Main display/card switches randomly after reboot...

Did you manage to figure this out? I'm having the same problem with my two 560 ti's - it's driving me mad!

[nofearl]

Unfortunately no, I've tried different DSDT hacks, bootloaders, editing windowserver.plist, BIOS settings, disconnecting one of the monitors, repairing color profiles, locking windowserver.plist files..

Maybe it's a OS bug.. One thing I haven't tried is using nvidia kexts from 10.7.x, but I have no idea which ones to rollback..

BTW, thank God it's not just me

[Andy4life]

I tried using the Keats from 10.7.4 it just hung while starting up :(8

I'm giving up, I've tried every trick I can think of..
