[Bug 459512] Re: X server aborts if two primary devices found

 

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.
