(Sorry I didn't see your message since I was subscribed to this bug report.)

I was able to get multiple monitors to work with PRIME using modesetting for
intel and nouveau for the NVIDIA card using X 1.20. The trick was to assign
drivers based on the BusID. The above error occurs when using modesetting for
both cards.

Tomorrow I can attach the Xorg log file with both cards using modesetting,
should I open a new bug for that?
