Since recent updates bumblebee stopped to disable my nvidia graphics card when there is no software running with optirun and primusrun. Bbswitch states that it's on, it's also making it's usual noise (another sign that it's on). Clean arch installation did nothing.

So after some search I found this:
https://github.com/Bumblebee-Project/Bu … issues/699
Unfortunately this issue was put in queue for bumblebee 4.0, so I dont think we'll have a fix soon. there are source code patches provided in a github discussion, but the easiest solution for me was to switch to nvidia-340xx legacy drivers.

There are quite a few solutions that don't involve waiting for the fix to be merged.
1) download bumblebee from aur / source, patch it yourself, compile it and install it.
2) manually unload the nvidia modules (sudo modprobe -r nvidia_modeset and then manually switch the GPU off using bbswitch (sudo tee /proc/acpi/bbswitch <<<OFF) and turn it back when needed (sudo tee /proc/acpi/bbswitch <<<ON).

Well it seems that legacy drivers didnt fix the problem completely. When running any random things with primusrun and optirun (for example, glxspheres64) it unloads the driver properly, but when I'm exiting blender (launched with primusrun) nvidia module remains loaded.

you can try this forked version of bumblebee https://github.com/arafey/Bumblebee#branch=master I use it and bumblebee now disables the card like expected
