"no CUDA-capable device is detected" for CUDA ver 7.5, Kubuntu 14.04

Accelerated Computing CUDA CUDA Setup and Installation
1

I am unable to run a cuda program on my nVidia card, please help.

I have a GEForce card (as described below) in the PCIe slot and my monitor is attached to the VGA port. I plan to use the GEForce card for cuda programming.
The nvidia driver is ver 352.79
I downloaded and used cuda_7.5.18_linux.run to install cuda. Followed the install process described in: Installation Guide Linux :: CUDA Toolkit Documentation

Device verification script is run successfully, env setup in .bashrc done,compiled the examples - specifically deviceQuery and here’s the output of running ./deviceQuery.

rinka@rinka-GPU:~/Documents/NVIDIA_CUDA-7.5_Samples/1_Utilities/deviceQuery
$ sudo ./deviceQuery
./deviceQuery Starting...

 CUDA Device Query (Runtime API) version (CUDART static linking)

cudaGetDeviceCount returned 10
-> invalid device ordinal
Result = FAIL

I really don’t know what I’m missing.

Hi rinka

You should check /var/lib/dkms/nvidia/build/make.log what happened on your installation.

Could you see the errors happened on your log?

As I posted some time ago, there are two weird behaviors I had to bypass in Ubuntu. First, the first time I run a Cuda program, I had to do sudo. Just verify if the Nvidia driver found its “rightful place” by running glmark2 first.

Second, recent Nvidia drivers were more willing to work with my machines if I was running Lubuntu and Xubuntu, so you may want to try “sudo apt-get install lubuntu-desktop” if all else fails.

  1. Is the v352.79 driver installed properly? (you can check it by $nvidia-smi or $dmesg | grep NVRM);
  2. Does it still happen after re-build the sample?
    $cd ~/NVIDIA_CUDA-7.5_Samples/1_Utilities/deviceQuery
    $make clean
    $make
