"A month or so ago, after the most recent OS X update (10.8.2), we’ve bumped into a problem that causes certain Macs to restart when intensively using Pixelmator. Sometimes, the app would stop responding without restarting a computer, or just cause some graphical glitches.


We did everything to find the root cause of the problem. We’ve researched a vast amount of information about OS X internals. We’ve torn down our Macs. We even reached out to Apple. Finally, the picture was clear: It’s an issue with NVIDIA GeForce graphics card drivers.*

* The following Macs with NVIDIA GeForce graphics cards are currently affected: GT 120, GT 320M, GT 330M, 9400M, and GT 9600."

I get random panics on 10.8/10.8.1. It says "com.apple.GeForce" but I can't find any solution to this? Any suggestions?

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!
