  cd /var/cache/apt/archives/
  sudo apt-get purge $(dpkg -l nvidia* | grep ii | cut -d" " -f3)
  sudo apt-get update
  sudo apt --no-install-recommends install nvidia-304*131*deb nvidia-settings_331*deb

nvidia-opencl-icd is just a recommended dependency, you might not need it.

"OpenCL (Open Computing Language) is a multivendor open standard for general-purpose parallel programming of heterogeneous systems that include CPUs, GPUs and other processors.

This package provides the NVIDIA installable client driver (ICD) for OpenCL which supports NVIDIA GPUs."
