In your modprobe.d directory there's the bumblebee.conf and
nvidia-kernel-common.conf, but not nvidia.conf. It should be there as a
symlink:

ls -l /etc/modprobe.d/ | grep nvidia.conf
lrwxrwxrwx 1 root root  43 Oct 17 11:46 nvidia.conf
-> /etc/alternatives/glx--nvidia-modprobe.conf

Try to run:

sudo update-glx --config glx

and choose "bumblebee", see if that reinstalls the symlink.

Did you fiddle with that file or with update-alternatives manually by
any chance?

Kind regards,
