Public bug reported: Unfortunately apport can't report from the right driver because nouveau ends up with a blank screen when running with three heads, and removing one or two doesn't recover without a reboot, and with a single head the system fails to get to a useable state because either unity or some other gui thing launches on boot repeatedly crashes.
