Ubuntu – Problem installing CUDA 8 on Ubuntu 16.04 – Missing proc/driver/nvidia folder

16.04cudadriversnvidia

I am trying to install NVIDIA CUDA 8.0 on my Ubuntu 16.04 LTS, even following the Linux Install Guide from NVIDIA I can not get it working.

Here is the details.

I have a laptop Acer Aspire VX, it cames with Windows 10 and I did a dual boot installation of Ubuntu.
The hardware is a Intel Core i5 7300HQ with an NVIDIA GeForce 1050.

The pre-installation actions and their output:

$ lspci | grep -i nvidia
01:00.0 3D controller: NVIDIA Corporation Device 1c8d (rev a1)

Until here everything was ok. Moreover, I install it following the pass by pass of the guide. I downloaded the file .deb from the NVIDIA site for Linux x86_64 machines.

  1. $ sudo dpkg -i /home/marlosdamasceno/Downloads/cuda-repo-ubuntu1604-8-0-local-ga2_8.0.61-1_amd64.deb
  2. $ sudo apt-get update
  3. $ sudo apt-get install cuda

That was ok as well. Aftet that I installed the Patch 2 (Released Jun 26, 2017). Here are the steps.

  1. $ sudo dpkg -i /home/marlosdamasceno/Downloads/cuda-repo-ubuntu1604-8-0-local-cublas-performance-update_8.0.61-1_amd64.deb
  2. $ sudo apt-get update
  3. $ sudo apt-get upgrade cuda

Everything looks like ok until here. Therefore, I follow the post-installation actions.

$ export PATH=/usr/local/cuda-8.0/bin${PATH:+:${PATH}}

$ nvcc --version
nvcc: NVIDIA (R) Cuda compiler driver
Copyright (c) 2005-2016 NVIDIA Corporation

Cuda compilation tools, release 8.0, V8.0.61

$ cuda-install-samples-8.0.sh /home/marlosdamasceno/

Ok, everything looks ok again, however here was the first problem, when I was checking the driver, there was no folder at all of nvidia. 

$ cat /proc/driver/nvidia/version

cat: /proc/driver/nvidia/version: No such file or directory

Here is a print of the folder: https: //ibb.co/cWjpTa

The only thing on the folder is a rtc file.

I tryed to keep going and did the make step of the samples.
I got this:

/usr/bin/ld: cannot find -lnvcuvid
collect2: error: ld returned 1 exit status
Makefile:381: recipe for target 'cudaDecodeGL' failed
make[1]: *** [cudaDecodeGL] Error 1
make[1]: Leaving directory '/home/marlosdamasceno/NVIDIA_CUDA-8.0_Samples/3_Imaging/cudaDecodeGL'
Makefile:52: recipe for target '3_Imaging/cudaDecodeGL/Makefile.ph_build' failed
make: *** [3_Imaging/cudaDecodeGL/Makefile.ph_build] Error 2

Moreover, when I ran the deviceQuery, I got this message.

./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

In addition, here are some more commands and outputs to help.

Nothing happens when typing this command.

$ lsmod | grep nvidia

Another command.

$ nvidia-smi
nvidia-smi: command not found

Another command.

$ sudo lshw -c video

So here are the questions.

I have Secure Boot enable, it is possible to be that?

The path file from the command export PATH=/usr/local/cuda-8.0/bin${PATH:+:${PATH}} always keep erasing it self. So when I do the command $ nvcc –version, I got the message.

The program 'nvcc' is currently not installed. You can install it by typing: sudo apt install nvidia-cuda-toolkit

How can I set the path and keep it that way?

Am I missing a step?

Thanks in advance for any help!!!

After a lot of effort for a new fella on Ubuntu I got it working!!!

@ubfan1 helped me when he said the command lshw -c video the hint I needed to know that I was not running on NVIDIA's driver.

After that I tried to install without success (the secure boot was off). I got this error: The system is running in low-graphics mode” (see this question). Therefore, I boot using the command **Alt+Ctrl+F1* and removed all files from NVIDIA using the command below.

sudo apt-get remove --purge nvidia-*

With that I could come back to my Desktop, where I could use the System Settings tool from Ubuntu to install the drivers (Software & Updates ->Addtional Drivers->Using NVIDIA binary -version 375.82 from nvidia-375 (open source). See the print:

NVIDIA Driver

I reboot the system and everything was installed!!! After that I tested the command ./deviceQuery from the bin inside the samples and the test PASS!

Lesson learned

Before to install CUDA, make sure all drivers of NVIDIA are running OK! You may install them like @ubfan1 suggest in this link.

Execute the following commands to check if the installation is the default and it is running.

$ cat /proc/driver/nvidia/version

Just to check the secure boot you can run.

$ mokutil --sb-state
