Comment 15 for bug 459512

Great, thanks for the testing! To follow up on the remaining loose threads...

From the log file, the crash with black is occurring much later in the boot cycle; it is setting primary and picking the driver correctly, it is just failing somewhere down the road. My guess is that there is also something in the driver that looks at the pci bus rather than honoring the primary display setting. In any case, since white works, we know we can bypass whatever the crash is.

As to the issue where the display isn't shown during boot, yes that's quite interesting - the kernel has decided the first card is primary, but black picks the secondary. So what you've described makes total sense... and again indicates that white is the more correct solution.

Regarding Joshua's issue, the patch clearly worked, it's just that with -nvidia you typically have to specify more in the xorg.conf than other drivers. From the log file it looks like it's getting past the issue with the primary card selection, but without the xorg.conf settings, it's trying to use the open -nv driver instead of -nvidia. I'd suggest testing with Driver "nvidia" included in xorg.conf but not the BusID, and if it still fails, open a new bug report.
