    How to install CUDA on Debian 8 (Jessie)

This document describes how to install nvidia drivers & CUDA in one go on a fresh debian install.
Work in progress
Preparations


Start with a fresh Debian install.


Download the CUDA driver with the following specifications:


Parameter
Type


Operating system
Linux


Architecture
x86_64


Distribution
Ubuntu


Version
14.04


Installer type
runfile (local)


The full link to this version as of the time this document was created:

http://developer.download.nvidia.com/compute/cuda/7.5/Prod/local_installers/cuda_7.5.18_linux.run


Change file permission of the installation file:
cd /home/john/Downloads/
chmod a+x ./cuda_*.run


Get necessary packages:
sudo apt-get update
sudo apt-get install dkms build-essential linux-headers-$(uname -r)


Install 32 bit support:
sudo dpkg --add-architecture i386
sudo apt-get update
sudo apt-get install lib32z1 lib32ncurses5


Blacklist the nouveau driver:
sudo mousepad /etc/modprobe.d/blacklist-nouveau.conf

Copy the following line into the document:
blacklist nouveau
blacklist lbm-nouveau
options nouveau modeset=0
alias nouveau off
alias lbm-nouveau off


Now reboot the system. If the nouveau was successfully disabled, the screen resolution should be lower.


Install the following packages:
sudo apt-get install gcc g++ gcc-4.8 g++-4.8 gcc-4.9 g++-4.9 libxi6 libxi-dev libglu1-mesa libglu1-mesa-dev libxmu6 linux-headers-amd64 linux-source freeglut3-dev


Install the nvidia driver & cuda


Reboot again, start system in init 3.
How to boot into init 3: When in starting screen press e to edit start commands, find relevant installation (quiet), add init 3


Log in as normal user, and activate su:
su


Navigate to downloads folder (or where ever you put the installer), run cuda installer:
cd /home/john/Downloads
sh ./cuda_7.5.18_linux.run


Follow the installer menu. You will be asked several questions:

Terms and condition? --> accept (If you feel like it...)

Unsupported version, proceed? --> yes

Install driver? --> yes

Install OpenGL? --> yes

Run nvidia-xconfig? --> 'yes' (This option is new in CUDA 8.0, not sure about the consequences.)

Install CUDA toolkit? --> yes

CUDA location? ---> /home/john/cuda-7.5

Create symbolic link at /usr/local? --> yes

Install samples? --> yes

CUDA samples location? --> /home/john/cuda-7.5_samples


Restart the system.
sudo reboot

This should start up successfully with GUI enabled (at native monitor resolution).


Add path exports to your .bashrc:
sudo gedit /home/john/.bashrc

Add the following lines:
# Manually added by john to enable CUDA:
export LD_LIBRARY_PATH=/home/john/cuda-7.5/lib64:$LD_LIBRARY_PATH
export LIBRARY_PATH=/home/john/cuda-7.5/lib64:$LIBRARY_PATH
export PATH=/home/john/cuda-7.5/bin:$PATH


Change permissions of cuda folders:
sudo chown -R john /home/john/cuda-7.5
sudo chgrp -R john /home/john/cuda-7.5
sudo chown -R john /home/john/cuda-7.5_samples
sudo chgrp -R john /home/john/cuda-7.5_samples


Check the result

Check whether the samples that do not require graphics ouput are working


Navigate to cuda samples location (as specified during installation):
cd /home/john/cuda-7.5_samples/0_Simple/simplePrintf


Generate executable:
make


An executable should have been created. Run it:
./simplePrintf


For samples that do require graphics ouput, the library paths need to be fixed.


Naviagte to a sample that does require graphics output, e.g.:
cd /home/john/cuda-7.5_samples/5_Simulations/nbody


Locate the libary files by running:
locate libGL.so
locate libGLU.so
locate libX11.so


Check which folder they are located in (e.g. /usr/lib/x86_64-linux-gnu).


In the samples folder, open findgllib.mk:
gedit /home/john/cuda-7.5_samples/5_Simulations/nbody/findgllib.mk


Search for the following if-condition:
ifeq ("$(TARGET_OS)","linux")
    # $(info) >> findgllib.mk -> LINUX path <<<)
    # Each set of Linux Distros have different paths for where to find their OpenGL libraries reside
    UBUNTU_PKG_NAME = "nvidia-352"
    UBUNTU = $(shell echo $(DISTRO) | grep -i ubuntu >/dev/null 2>&1; echo $$?)
    ...

and replace it with the following code:
ifeq ("$(TARGET_OS)","linux")
    GLPATH    ?= /usr/lib/x86_64-linux-gnu
    GLLINK    ?= -L/usr/lib/x86_64-linux-gnu
    DFLT_PATH ?= /usr/lib64


Generate executable:
make


An executable should have been created. Run it:
./nbody
