nofearl Posted July 12, 2012 Share Posted July 12, 2012 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!

nofearl Posted July 13, 2012 Author Share Posted July 13, 2012 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. Link to comment Share on other sites More sharing options...
nofearl Posted July 13, 2012 Author Share Posted July 13, 2012 Scratch that, still not working. Main display/card switches randomly after reboot... Link to comment Share on other sites More sharing options...
Andy4life Posted July 14, 2012 Share Posted July 14, 2012 Did you manage to figure this out? I'm having the same problem with my two 560 ti's - it's driving me mad! Link to comment Share on other sites More sharing options...
nofearl Posted July 14, 2012 Author Share Posted July 14, 2012 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 Link to comment Share on other sites More sharing options...
