Comment 8 for bug 1268217

I'm not familiar with bumblebee but I'm pretty sure nvidia-prime per se is not the problem here. All the heavy lifting is done by the gpu-manager binary in the ubuntu-driver-common package. If you give me an easy way to check if bumblebee is in use (e.g. checking the existence of a file, etc.), I'll make sure that the gpu-manager doesn't modify the system when this is the case.
