I have a weirds problems with ubuntu 15 when I try install bumblebee on my MSI GS60-2QE.
I had try many installations way especialy this one: How to install nVidia drivers with Bumblebee on Ubuntu 14.04
I only change the driver version: "nvidia-346-updates". But the problem persists. He look like this :
optirun -vv glxspheres

I also generate a bumblebee bug-report, can be found here : Bug Report
If anyone has had the same problem and managed to solve it. I'd love he shares how to proceed.
