NVIDIA OpenCL on Trusty or Mint 17

It is very difficult for me to get OpenCL to work in Trusty or Mint 17. I use ppa: xorg-edgers, verified updates, and even nvidia-340.

sudo apt-get install nvidia-331 nvidia-331-uvm nvidia-cuda-toolkit nvidia-cuda-dev opencl-headers nvidia-opencl-dev clinfo

Reboot and then

babak@ASUS-G750JH:~$ clinfo
clinfo: /usr/lib/x86_64-linux-gnu/libOpenCL.so.1: no version information available (required by clinfo)
I: ICD loader reports no usable platforms

I tried this on two Intel-based systems with an Nvidia GPU on a desktop computer with a GeForce 280 and a laptop with a GeForce 780M with Asus physically disabled, it only has an Nvidia GPU. G750JH.

Has anyone done this successfully? Can I roll back and remove the PPA and use the default repo, can this even change?
