Hello Alexander,

The problem was that the nvidia's modprobe conf was moved to
glx-alternative and it was not configured (since on a bumblebee setup
glx is served by mesa). This was fixed by Andreas with a new diversion
specifically for bumblebee setups. I'm not seeing issues now with
modprobe -r nvidia.

The reason for the change was that the old version broke when
nvidia-current and nvidia-legacy-YYYxx were installed.

Kind regards,
