Nvidia CUDA Toolkit Installation (Ubuntu 16.04 LTS) - Notes

Successfully installed Nvidia CUDA toolkit (which includes Nvidia driver) to Ubuntu 16.04 LTS on 30th May 2017 - here are some notes for sharing.

Major learning:

  • Disable Secure Boot at UEFI Firmware setting (do this in BIOS mode / restart from Windows advanced startup). (I did try for ages hoping I could get it working with Secure Boot enabled. No luck Secure Boot stopped the Nvidia driver from installing properly on Ubuntu. Disabling Secure Boot turns out to be the only working solution for me - if you are able to get Nvidia driver installed without having to disable Secure Boot, do let me know)
  • Follow the Linux CUDA Installation Guide.
  • (opinionated...) Use the Linux .deb (package manager) installation (for simplicity.). Download the .deb file in a browser. Install from terminal command line.
  • (opinionated...) Don't use runfile installation (too complicated).

Download the Ubuntu package

  • Download here.
  • Linux -> x86_64 -> Ubuntu -> 16.04 -> deb (local)
  • Do checksum to ensure package is downloaded correctly. i.e. md5sum xxx.deb should output the same string as the one published in

Do the pre-installation checks:

Verify computer is Nvidia driver / toolkit compatible.

johnny@johnny-XPS-8700:~$ lspci | grep -i nvidia
01:00.0 VGA compatible controller: NVIDIA Corporation GM107 [GeForce GTX 750 Ti] (rev a2)
01:00.1 Audio device: NVIDIA Corporation Device 0fbc (rev a1)

Following tells you which Nvidia toolkit to download (Ubuntu x86_64). Verify if compatible.

johnny@johnny-XPS-8700:~$ uname -m && cat /etc/*release
VERSION="16.04.2 LTS (Xenial Xerus)"
PRETTY_NAME="Ubuntu 16.04.2 LTS"

Verify GCC version is installed...

johnny@johnny-XPS-8700:~$ gcc --version
gcc (Ubuntu 5.4.0-6ubuntu1~16.04.4) 5.4.0 20160609
Copyright (C) 2015 Free Software Foundation, Inc.
This is free software; see the source for copying conditions.  There is NO

Verify correct kernel and header.

johnny@johnny-XPS-8700:~$ uname -r

The kernel headers and development packages for the currently running kernel can be installed with:

johnny@johnny-XPS-8700:~$ sudo apt-get install linux-headers-$(uname -r)
[sudo] password for johnny: 
Reading package lists... Done

0 to upgrade, 0 to newly install, 0 to remove and 175 not to upgrade.

Do the Installation

sudo dpkg -i cuda-repo-ubuntu1604-8-0-local-ga2_8.0.61-1_amd64.deb
sudo apt-get update
sudo apt-get install cuda

Reboot to take effect.

sudo reboot

Post Installation Actions

Create / update the environmental variables PATH and LD_LIBRARY_PATH. To make this change permenantly, do a `gedit ~/.profile', add the following lines at the bottom:

export PATH=/usr/local/cuda/bin:$PATH
export LD_LIBRARY_PATH=/usr/local/cuda/lib64:$LD_LIBRARY_PATH

Note that cuda in the path name actually is a symbolic link points to cuda-8.0 (in my case).

Save the file, log out and log in to take effect.

Once logged back in, do some more checks...

Copy sample files from a root owned (read only) area to a user specific writable area (say, ~/jccuda).

johnny@johnny-XPS-8700:~$ ~/jccuda

Navigate to ~/jccuda/NVIDIA_CUDA-8.0_Samples. Issue make to compile some files. (there will be lots of warning and some errors. Not critical).

When done, go to ~/jccuda/NVIDIA_CUDA-8.0_Samples/bin/x86_64/linux/release and test out some commands.

deviceQuery should produce something meaningful...

Looks good!

In addiiton, search for nvidia at the Ubuntu search button (top left) should show some Nvidia apps.
