I just ran into this problem on ubuntu 14.04 and I could not find ANY working answers anywhere online including this thread (though this was the first to show up on google).

Installing the components through apt-get seems to fail for some reason.

1) Download CUDA .run file: https://developer.nvidia.com/cuda-downloads

2) Purge all previous nvidia packages

sudo apt-get purge nvidia-*

3) Install all run file components (you will likely have to stop X or restart in recovery mode to run this)

sudo sh cuda_X.X.XX_linux.run
