I'm planning to start some CUDA development, so I'm trying to use the NVIDIA card that I have installed and I haven't yet be able to use (an NVIDIA Corporation GF108M [GeForce GT 630M]) because Ubuntu (12.05 64 bits)seems to have many issues with it.

What I did is download the CUDA 5.5 installers and execute the following in that order:

To make the NVIDIA driver installation to work, I have to uninstall Bumblebee first. The installer wanted to override xorg.conf but I choose not to because some previous disastrous installations (I only get a black screen).

I used this Blog Post instructions to validate my installation. I first executed this:

cptanalatriste@cptanalatriste-Inspiron-5420:/usr/local/cuda-5.5/lib64$ cat /proc/driver/nvidia/version
cat: /proc/driver/nvidia/version: No such file or directory

And I get that error message. After compiling and executing the CUDA samples. I'm getting this:

cptanalatriste@cptanalatriste-Inspiron-5420:/usr/local/cuda-5.5/samples/1_Utilities/deviceQuery$ sudo ./deviceQuery 
./deviceQuery Starting...

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

WARNING: Not loading blacklisted module nvidia_304
FATAL: Module nvidia not found.
cudaGetDeviceCount returned 38
-> no CUDA-capable device is detected
Result = FAIL

Any ideas? I suspect the Driver installation didn't go that well.
