devQuery can not find device

Hi All,
My system is ubuntu 11.4.
But I’m not sure the model of my graphic chip, on my notebook, there is only a trademark “nvidia NVS with cuda”.
So, I install three package on my notebook
1.CUDA Toolkit for Ubuntu Linux 10.10
2.CUDA Tools SDK
3.GPU Computing SDK code samples
For my system is 11.4, I chomd +x the “*.run” and run “./”(not “sh”). Everything ok,then I make the GPU code sample,there is no error and all pass.But when I run “./devQuery”, it can not find any device.

What driver have you installed?
