title: Is CUDA in installed correctly on my Ubuntu 10.04? Some samples don't run.
body: <p>I am trying to install CUDA on a server running Ubuntu 10.04.</p>
  
  <p>I followed the NVDIA instructions and installed the "CUDA toolkit for Ubuntu Linux 10.04", "GPU Conputing SDK code samples",and "Developer Drivers for Linux (260.19.26) (64 bit)", my system is 64 bit. This installation seems successful. everything downloaded from <a href="http://developer.nvidia.com/object/cuda_3_2_downloads.html#Linux" rel="nofollow noreferrer">http://developer.nvidia.com/object/cuda_3_2_downloads.html#Linux</a></p>
  
  <p>According to the messages of the installation packages, I added /usr/local/cuda/bin to PATH, /usr/local/cuda/lib64:/usr/local/cuda/lib to LD_LIBRARY_PATH</p>
  
  <p>Then, I tried to run the sample programs. The strange things is, some of them can be run, and some of them don't even through they can be made with no problem. </p>
  
  <p>For example,<br>
  - <code>convolutionSeparable</code> will just stop there without any message, I can kill it by ctrl + c. </p>
  
  <ul>
  <li><p><code>matrixMul</code> outputs a line </p>
  
  <p><code>Device 0: "Quadro 5000" with Compute 2.0 capability</code></p>
  
  <p>and stop there, again can be killed by Ctrl+C</p></li>
  <li><p><code>clock</code> works, outputs</p>
  
  <p><code>PASSED</code><br>
  <code>time = 12574</code><br>
  <code>Press ENTER to exit...</code></p></li>
  <li><p><code>simpleMultiCopy</code> outputs <code>PASSED</code></p></li>
  <li><p><code>MonteCarlo</code> outputs <code>PASSED</code></p></li>
  <li><p><code>simpleZeroCopy</code> outputs <code>PASSED</code></p></li>
  <li><p><code>bandwidthTest</code> stops there with blinking cursor for ever. </p></li>
  </ul>
  
  <p>What is wrong with this?! How can I check if my CUDA installation is successful ? What is wrong with those programs don't run? They don't even have a error message.</p>
