Both unity-system-compositor and X have crashed, which indicates to me that Mir has failed for some reason. In /var/log/unity-system-compositor.log we have:
terminate called after throwing an instance of 'boost::exception_detail::clone_impl<boost::exception_detail::error_info_injector<std::runtime_error> >'
what(): Output has no associated crtc
Which is Mir failing to get an output to render to.
