(Guide) Installing Nvidia + Bumblebee + CUDA for Optimus enabled Laptops

[Rarity]

One more thing.. I realized that if I edit /etc/bumblebee/xorg.conf.nvidia and don't run the /etc/init.d/bumblebee restart command after, optirun glxspherest64 works, but only once. Here's the optirun and dmesg after it works for the first time.

optirun glxspheres64

Polygons in scene: 62464
Visual ID of window: 0x21
Context is Direct
OpenGL Renderer: GeForce GT 750M/PCIe/SSE2

dmesg

Everything after the second "this pci device is not a vga device" ([ 1220.019129]) is after I close out of the glxsphere window.
Thanks for your help!

edit:

I had thought I read all of the posts before posting but it seems I may have missed one.

Using the solution tonrin posted worked for me too!

Still lots of errors in dmesg but deviceQuery results in a pass!
