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

[Rarity]

bahha, is there any way to install the updated NVIDIA driver with CUDA 6.5 without breaking the Intel graphics card?

I'd rather do one installation instead of install/uninstall/install again.

Yes there is, The one I'm pretty sure about is to install the nvidia driver from the repository and add debian sid repository

deb http://http.us.debian.org/debian/ sid main non-free contrib

in order to upgrade the driver to a version that supports
CUDA 6.5 and then remove the repo from source.list .

I'm not sure if the proprietary driver form nvidia website which is posted in the first page of this thread, breaks the Intel. It did break mine a while ago and I fixed it with the repo driver . and never tried it again, as
everything is working fine now .
