CUDA 9.0 deviceQuery fails: "CUDA driver version is insufficient for CUDA runtime version"

Accelerated Computing CUDA CUDA Setup and Installation
1

After following this guide to the dot (http://developer.download.nvidia.com/compute/cuda/9.0/Prod/docs/sidebar/CUDA_Installation_Guide_Linux.pdf) to install CUDA 9.0, I attempted to build the samples at `NVIDIA_CUDA-9.0_Samples/, but this resulted in a make error.

I followed a suggestion to build just deviceQuery, but when I run ./deviceQeury, I get the following output:

krishna@krishna-ubuntu:~/Documents/NVIDIA_CUDA-9.0_Samples/1_Utilities/deviceQuery$ ./deviceQuery 
./deviceQuery Starting...

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

cudaGetDeviceCount returned 35
-> CUDA driver version is insufficient for CUDA runtime version
Result = FAIL

Note that I’m running a dual boot on a laptop that also has an iGPU.

Is this error normal, and if not, how can I fix it?

2

update the GPU driver from a proper NVIDIA source (not ppa)

3

Do I need to purge CUDA before updating my GPU driver?

4

I installed CUDA via sudo apt-get install cuda.
Does this not install the required GPU drivers as well?

5

it should. Your driver install may be broken. Laptops can be tricky to get working correctly. If the dGPU is disabled dynamically, you’ll have this trouble.

Thanks.
Is there any official resource I can follow to make sure I install the GPU driver the right way?

The GPU driver has a readme file. For example:
