No. bumblebee-nvidia is a meta package which installs both the bumbelbee and nvidia-driver packages. The nvidia-driver package in the repo is old and not supported by many modern graphics cards. That is why the driver package is downloaded from the nvidia website.
If you are stuck on the nvidia driver and will not swap to the power saving one, try
service bumblebeed restart
and
service bumblebeed status
Also, how do you know the driver is being loaded and not being switched off?
For example, run
Code:
optirun glxspheres64
and then run
Did the second command work without optirun?
