title: Cuda driver initialization failed
body: <p>I have a two gpu system, a Geforce 8400 GS and Geforce GT 520. I am able to run my cuda programs on both the gpus. But when I use cuda-gdb to debug them I get an error saying that the <code>Cuda driver initialization failed.</code> Also, when I run the program with <code>cuda-gdb</code>, the <code>cudaGetDeviceCount</code> says I have only 1 gpu. I am able to run the programs on either of the gpus if I am not using <code>cuda-gdb</code>. Can somebody help me with this?</p>
  
  <p>I am running Ubuntu 11.04. </p>
