It wont switch to Intel. Also should we not be installing bumblebee-nvidia as we are now using official drivers?
Kali boots using Intel and as soon as you use optirun or primerun it loads Nvidia and then never switches it off.

Please post the output of

lsmod

and

cat /proc/acpi/bbswitch

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

Code:
glxspheres64
Did the second command work without optirun?
