title: What is the correct version of CUDA for my nvidia driver?
body: <p>I am using ubuntu 14.04. I want to install CUDA. But I don't know which version is good for my laptop. I trace my driver that is:</p>
  
  <pre><code>$cat /proc/driver/nvidia/version
  
  NVRM version: NVIDIA UNIX x86_64 Kernel Module  304.125  Mon Dec  1 19:58:28 PST 2014
  GCC version:  gcc version 4.8.2 (Ubuntu 4.8.2-19ubuntu1) 
  </code></pre>
  
  <p>I tried to install CUDA <code>cuda-linux64-rel-7.0.28-19326674</code> but when I test by command:</p>
  
  <pre><code>./deviceQuery
  ./deviceQuery Starting...
  
   CUDA Device Query (Runtime API) version (CUDART static linking)
  
  cudaGetDeviceCount returned 35
  -&gt; CUDA driver version is insufficient for CUDA runtime version
  Result = FAIL
  </code></pre>
  
  <p>Could you help me resolve that problem? I reinstalled my Ubuntu many times. </p>
