No CUDA / GPU option in preferences in blender. Blender does not recognize GTX 860M under Linux Mint 17 (Ubuntu 14.10)
OS: Linux Mint 17 64bit KDE
GPU: NVIDIA GTX 860M hybrid
Driver: NVIDIA 340.32 drivers and NVIDIA X Server settings with (PRIME) settings set to force the GTX GPU as active.
2.71 and I downloaded it via $ sudo add-apt-repository ppa:irie/blender
I’ve also tried using the download package from blender.org, same thing…
Other things I’ve tried:
using various other driver packages (331) (337)
Also installed CUDA Toolkit - sudo apt install nvidia-cuda-toolkit
This also came back:

The OP solution didn’t work for me, since installing Cuda 6.5 or higher requires (at least in Ubuntu) to install nvidia-346, which got me a black screen and I had to downgrade back to nvidia-331. Installing modprobe also didn’t work, but
Downgrading all the nvidia-331 packages from 331.113 to 331.38 did the trick. To do this in Ubuntu, go to Synaptic Package Manager, find the nvidia-331 packages (in my case nvidia-331-uvm, nvidia-331, nvidia-opencl-icd-331, libcuda1-331 and nvidia-libopencl1-331), select each one of them, go to Package>Force Version and apply it. Be careful though, as the package manager may make you update the packages again, so every time you downgrade, lock the version in Package>Lock Version.
Anyway, do this at your own risk, since the other solutions didn’t work for me, this one may not work for you as well.
