Step by step

1. disable nouveau

sudo bash -c "echo blacklist nouveau > /etc/modprobe.d/blacklist-nvidia-nouveau.conf"
sudo bash -c "echo options nouveau modeset=0 >> /etc/modprobe.d/blacklist-nvidia-nouveau.conf"
sudo update-initramfs -u
# sudo reboot

lsmod | grep nou # check nouveau is not running

2. Install driver

2.1 Check devices:

sudo lshw -C display

2.2 Download the appropriate driver for the gpu devicee and run

• https://www.nvidia.com/Download/index.aspx?lang=en-us
• https://www.nvidia.com/content/DriverDownload-March2009/confirmation.php?url=/XFree86/Linux-x86_64/470.63.01/NVIDIA-Linux-x86_64-470.63.01.run&lang=us&type=TITAN

curl https://us.download.nvidia.cn/XFree86/Linux-x86_64/470.63.01/NVIDIA-Linux-x86_64-470.63.01.run -o NVIDIA-Linux-x86_64-470.63.01.run
sudo chmod a+x NVIDIA-Linux-x86_64-470.63.01.run
sudo ./NVIDIA-Linux-x86_64-470.63.01.run

One or more modprobe configuration files to disable Nouveau have been written.  For some distributions, this may be sufficient to disable Nouveau; other distributions may require modification of the initial ramdisk.  Please 
  reboot your system and attempt NVIDIA driver installation again.  Note if you later wish to re-enable Nouveau, you will need to delete these files: /usr/lib/modprobe.d/nvidia-installer-disable-nouveau.conf,
  /etc/modprobe.d/nvidia-installer-disable-nouveau.conf

[xvno]

3. install CUDA

sudo apt install nvidia-cuda-toolkit
nvcc -V

Not so ideal... so try this:

wget https://developer.download.nvidia.com/compute/cuda/11.4.1/local_installers/cuda_11.4.1_470.57.02_linux.run
sudo sh cuda_11.4.1_470.57.02_linux.run

[xvno]

4. Reinstall CUDA

sudo apt purge nvidia-cuda-toolkit
#Run NVIDIA driver installer again but it returns error. restart the server

# Switch a default GCC version
sudo apt -y install gcc-7 g++-7
sudo update-alternatives --install /usr/bin/gcc gcc /usr/bin/gcc-7 7
sudo update-alternatives --install /usr/bin/g++ g++ /usr/bin/g++-7 7

# Install from installer
curl http://developer.download.nvidia.com/compute/cuda/10.2/Prod/local_installers/cuda_10.2.89_440.33.01_linux.run -o cuda_10.2.89_440.33.01_linux.run
chmod u+x cuda_10.2.89_440.33.01_linux.run
sudo sh cuda_10.2.89_440.33.01_linux.run

Add in .bashrc

PATH=/usr/local/cuda-10.2/bin:$PATH
export LD_LIBRARY_PATH=/usr/local/cuda-10.2/lib64

Add in /etc/ld.so.conf.

include /usr/local/cuda-10.2/lib64

[xvno]

5. Sample CUDA code to test

git clone https://github.com/NVIDIA/cuda-samples.git
cd cuda-samples/Samples/simpleCUBLAS
vim Makefile
# Change the Location of the CUDA Toolkit
# CUDA_PATH ?= /usr/lib/nvidia-cuda-toolkit
mkake
./simpleCUBLAS

[xvno]

Add in .bashrc

PATH=/usr/local/cuda-10.2/bin:$PATH
export LD_LIBRARY_PATH=/usr/local/cuda-10.2/lib64

Add in /etc/ld.so.conf.

include /usr/local/cuda-10.2/lib64
