Well, I've just reinstalled nvidia-331 and its dependencies to recreate the problem with the nvidia-prime package, and this time my xorg.conf was left untouched, even after a reboot. This had never been the case before, so wasn't the case yesterday when I attached the gpu-manager.log in comment #3. (It was the same nvidia-331 version, though -- 331.38-0ubuntu7.) Something to do with the kernel update? Either way, thanks :)
