Ubuntu – NVIDIA-SMI has failed because it couldn’t communicate with the NVIDIA driver. Make sure that the latest NVIDIA driver is installed and running


I just installed CUDA in a notebook like this:

sudo apt-get install cuda

Like said here.

The compilation wokrs just fine but when I try to run I got the followin problem:
CUDA error at file.cu:128 code=35(cudaErrorInsufficientDriver) "cudaStreamCreate(&(stream[i]))"

My nvcc version:

nvcc: NVIDIA (R) Cuda compiler driver
Copyright (c) 2005-2016 NVIDIA Corporation
Built on Tue_Jan_10_13:22:03_CST_2017
Cuda compilation tools, release 8.0, V8.0.61

Graphics card info:

lspci | egrep 'VGA|3D'
00:02.0 VGA compatible controller: Intel Corporation Skylake Integrated Graphics (rev 06)
02:00.0 3D controller: NVIDIA Corporation GM107M [GeForce GTX 960M] (rev a2)

I also installed VirtualGL, bumblebee-nvidia, primus, freeglut3-dev.
Following this.

When I try to run something on bumblebee I got this:
optirun glxspheres64

[   41.413478] [ERROR]Cannot access secondary GPU - error: Could not load GPU driver
[   41.413520] [ERROR]Aborting because fallback start is disabled.

nvidia driver not working.

NVIDIA-SMI has failed because it couldn't communicate with the NVIDIA driver. Make sure that the latest NVIDIA driver is installed and running.

It looks like the nvidia 375 version is instaled but I can't make it works.

I think it can be some driver version problem:

dpkg -l | grep nvidia

What am I missing?

Best Answer

If your nvidia-smi failed to communicate but you've installed the driver so many times, check prime-select.

  1. Run prime-select query to get all possible options. You should see at least nvidia | intel.
  2. Choose prime-select nvidia.
  3. If it says nvidia is already selected, select a different one, e.g. prime-select intel, then switch back to nvidia prime-select nvidia
  4. Reboot and check nvidia-smi.
