title: Where did CUDA get installed in my computer?
body: <p>I'm trying to install CUDA 7.5 in my ubuntu 14.04. I followed everything in this guide (installation through package): <a href="http://developer.download.nvidia.com/compute/cuda/7.5/Prod/docs/sidebar/CUDA_Installation_Guide_Linux.pdf" rel="noreferrer">http://developer.download.nvidia.com/compute/cuda/7.5/Prod/docs/sidebar/CUDA_Installation_Guide_Linux.pdf</a> until post build section. Mainly, by running the following commands: </p>
  
  <pre><code>sudo dpkg -i cuda-repo-ubuntu1404-7-5-local_7.5-18_amd64.deb
  sudo apt-get update
  sudo apt-get install cuda
  </code></pre>
  
  <p>The thing is the folder /usr/local/cuda* does not exist after successful CUDA installation. Further trying to install cuda says that it is already the newest version.</p>
  
  <pre><code>sudo apt-get install cuda
  Reading package lists... Done
  Building dependency tree       
  Reading state information... Done
  cuda is already the newest version.
  
  ls /usr/local/cuda*
  ls: cannot access /usr/local/cuda*: No such file or directory
  </code></pre>
  
  <p>It also does not find nvcc.</p>
  
  <pre><code>nvcc
  The program 'nvcc' is currently not installed. You can install it by typing:
  sudo apt-get install nvidia-cuda-toolkit
  
  sudo find /usr/ -name nvcc
  &lt;no output&gt;
  </code></pre>
  
  <p>What is wrong?</p>
