Quick Apt Repository way – NVIDIA CUDA 9.x on Ubuntu 18.04 LST installation

The same NVIDIA CUDA 9.1 setup on Ubuntu 18.04 LST using the aptitude repository. However this appears to work and is simple to work with. Reference is taken from this askubuntu discussion.

Lookup the solution to the Nouveau issue from this blogpost

sudo add-apt-repository ppa:graphics-drivers/ppa
sudo apt update
sudo ubuntu-drivers autoinstall
sudo reboot

Now install the CUDA toolkit

sudo apt install g++-6
sudo apt install gcc-6
sudo apt install nvidia-cuda-toolkit gcc-6

Setup the environment variables

# Environment variables
export PATH=/usr/local/cuda-9.1/bin${PATH:+:${PATH}}
export LD_LIBRARY_PATH=${LD_LIBRARY_PATH}:/usr/local/cuda-9.1/lib64 
export LD_LIBRARY_PATH=${LD_LIBRARY_PATH}:/usr/local/cuda-9.1/lib

Provide the soft link for the gcc-6 compiler

sudo ln -s /usr/bin/gcc-6 /usr/local/cuda/bin/gcc
sudo ln -s /usr/bin/g++-6 /usr/local/cuda/bin/g++
sudo reboot

Test

cd ~/NVIDIA_CUDA-9.1_Samples/
make -j4

Upon completion of the compilation test using device query binary

$ cd ~/NVIDIA_CUDA-9.1_Samples/bin/x86_64/linux/release
$ ./deviceQuery

$ sudo bash -c "echo /usr/local/cuda/lib64/ > /etc/ld.so.conf.d/cuda.conf"
$ sudo ldconfig

NVIDIA CUDA 9.x on Ubuntu 18.04 LST installation

Guide

An installation guide to take you through the NVIDIA graphics driver as well as CUDA toolkit setup on an Ubuntu 18.04 LTS.

A. Know your cards

Verify what graphics card you have on your machine

rahul@karma:~$ lspci | grep VGA
04:00.0 VGA compatible controller: 
NVIDIA Corporation GM204 [GeForce GTX 970] (rev a1)
rahul@karma:~$ sudo lshw -C video
 *-display

Download the right driver

downloaded the Version 390.67 for GeForce GTX 970

B. Nouveau problem kills your GPU rush

Hoever there are solutions available

Here is what worked for me

  1. remove all nvidia packages ,skip this if your system is fresh installed
    sudo apt-get remove nvidia* && sudo apt autoremove
    
  2. install some packages for build kernel:
    sudo apt-get install dkms build-essential linux-headers-generic
    
  3. now block and disable nouveau kernel driver:
    sudo vim /etc/modprobe.d/nvidia-installer-disable-nouveau.conf
    

Insert follow lines to the nvidia-installer-disable-nouveau.conf:

blacklist nouveau
blacklist lbm-nouveau
options nouveau modeset=0
alias nouveau off
alias lbm-nouveau off

save and exit.

  1. Disable the Kernel nouveau by typing the following commands(nouveau-kms.conf may not exist,it is ok):
    rahul@wind:~$ echo options nouveau modeset=0 | sudo tee -a /etc/modprobe.d/nouveau-kms.conf
    options nouveau modeset=0
    
  2. build the new kernel by:
    rahul@wind:~$ sudo update-initramfs -u
    update-initramfs: Generating /boot/initrd.img-4.15.0-23-generic
    
  3. reboot
Run the Installer in run-level 3
$ sudo init 3 
$ sudo bash
$ ./NVIDIA-Linux-x86_64-390.67.run

Uninstall

More instruction on how to stop using the driver before uninstallation
sudo nvidia-installer –uninstall

C. NVIDIA X Server Settings

Install this from the ubuntu software center.

D. Start the CUDA related setup

We will need the CUDA toolkit 9.1 which is supported for the GTX 970 version with compute 3.0 capability. So download the local installer for Ubuntu.

Screenshot from 2018-07-13 13-55-24.png

Downloaded the “cuda_9.1.85_387.26_linux.run*” local installation file.

$ sudo add-apt-repository ppa:graphics-drivers/ppa
$ sudo apt install nvidia-cuda-toolkit gcc-6

Steps are taken from the CUDA 9.1 official documentation

  1. Perform the pre-installation actions.
  2.  Disable the Nouveau drivers. We did this in the above driver installation
  3. Reboot into text mode (runlevel 3). This can usually be accomplished by adding the number “3” to the end of the system’s kernel boot parameters. Change the runlevel ‘sudo init 3’, refer
  4. Verify that the Nouveau drivers are not loaded. If the Nouveau drivers are still loaded, consult your distribution’s documentation to see if further steps are needed to disable Nouveau.
  5. Run the installer and follow the on-screen prompts:
$ chmod +x cuda_9.1.85_387.26_linux
$ rahul@wind:~/Downloads$ ./cuda_9.1.85_387.26_linux --override

Screenshot from 2018-07-13 13-52-19.png

Since we already installed the Driver above we say NO in the NVIDIA accelerated graphic driver installation question.

Screenshot from 2018-07-13 13-54-20.png

This will install the CUDA stuff in the following locations

  • CUDA Toolkit /usr/local/cuda-9.1
  • CUDA Samples $(HOME)/NVIDIA_CUDA-9.1_Samples

We can verify the graphic card using the NVIDIA-SMI command.

Uninstallation

cd /usr/local/cuda-9.1/bin
sudo ./uninstall_cuda_9.1.pl

 

E. Environment Variables

rahul@wind:~$ vim ~/.bashrc

# Add the following to the environment variables
export PATH=/usr/local/cuda-9.1/bin${PATH:+:${PATH}}
export LD_LIBRARY_PATH=${LD_LIBRARY_PATH}:/usr/local/cuda-9.1/lib64 
export LD_LIBRARY_PATH=${LD_LIBRARY_PATH}:/usr/local/cuda-9.1/lib

rahul@wind:~$ source ~/.bashrc
rahul@wind:~$ nvcc --version

F. Test

Ensure you have the right driver versions

rahul@wind:$ cat /proc/driver/nvidia/version
NVRM version: NVIDIA UNIX x86_64 Kernel Module 390.67 Fri Jun 1 04:04:27 PDT 2018
GCC version: gcc version 7.3.0 (Ubuntu 7.3.0-16ubuntu3)

Change directory to the NVIDIA CUDA Samples and compile them

rahul@wind:~/NVIDIA_CUDA-9.1_Samples$ make

Now run the device query test

rahul@wind:~/NVIDIA_CUDA-9.1_Samples/bin/x86_64/linux/release$ ./deviceQuery
./deviceQuery Starting...

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