Packages installation for ubuntu

Note:All the following described installation methods have been implemented and completed sucessfully on my desktop(ubuntu) or notebook(ubuntu)! Without doubt, I aslo saw errors confusing me and ended up with falling before because it is new to me !And it really wasted time i think!Now I get it and know how to install them more efficiently and simply with NO MISTAKE! I hope it is hopeful for you!

1> INSTALLING CUDA( CUDA Toolkit v10.0.130 as an example)

Here are two methods:

1)Package Manager installation: This method is very simple.Moreover,you need not NVIDIA-drive as prerequisite.Make sure you download correct RPM or Deb packages for you system.More details seen at https://docs.nvidia.com/cuda/index.html

2)Runfile installation:Although NVIDIA official website recommended to use above method I prefer to choose this method.The .run package has the advantages of working across a wider set of Linux distributions and uninstalling and reinstalling it easily(via $ sudo /usr/local/cuda-10.0/bin/uninstall_cuda_10.0.pl).You can choose needful applications or packeges which the package contains.For example.If you need not NVIDIA-driver just unselect it.

steps: One: execute Pre-installation action in https://docs.nvidia.com/cuda/cuda-installation-guide-linux/index.html#pre-installation-actions

1.1. Verify You Have a CUDA-Capable GPU

  $ lspci | grep -i nvidia

1.2. Verify You Have a Supported Version of Linux
  $ uname -m && cat /etc/*release

1.3. Verify the System Has gcc Installed

   $ gcc --version

1.4. Verify the System has the Correct Kernel Headers and Development Packages Installed

 $ uname -r

    RHEL/CentOS 
       $ sudo yum install kernel-devel-$(uname -r) kernel-headers-$(uname -r)
    Fedora
       $ sudo dnf install kernel-devel-$(uname -r) kernel-headers-$(uname -r)
    OpenSUSE/SLES
       $ uname -r
       3.16.6-2-default
       $ sudo zypper install kernel-<variant>-devel=<version>
    Ubuntu
      $ sudo apt-get install linux-headers-$(uname -r)
      
 1.5. Download the NVIDIA CUDA Toolkit
    The NVIDIA CUDA Toolkit is available at http://developer.nvidia.com/cuda-downloads.

Two:

 2.1 The Nouveau drivers are loaded if the following command prints anything:
        $ lsmod | grep nouveau
 
 To install the Display Driver, the Nouveau drivers must first be disabled. Each distribution of Linux has a different
method for disabling Nouveau.

Fedora
  Create a file at /usr/lib/modprobe.d/blacklist-nouveau.conf with the following contents:
         blacklist nouveau
         options nouveau modeset=0
  Regenerate the kernel initramfs:
         $ sudo dracut --force
  Run the below command:
         $ sudo grub2-mkconfig -o /boot/grub2/grub.cfg
  Reboot the system.

RHEL/CentOS
  Create a file at /etc/modprobe.d/blacklist-nouveau.conf with the following contents:
     blacklist nouveau
     options nouveau modeset=0
  Regenerate the kernel initramfs:
     $ sudo dracut --force

OpenSUSE
  Create a file at /etc/modprobe.d/blacklist-nouveau.conf with the following contents:
      blacklist nouveau
      options nouveau modeset=0
 Regenerate the kernel initrd:
      $ sudo /sbin/mkinitrd

Ubuntu
  Create a file at /etc/modprobe.d/blacklist-nouveau.conf with the following contents:
     blacklist nouveau
     ptions nouveau modeset=0
  Regenerate the kernel initramfs:
     $ sudo update-initramfs -u

2.2 Reboot into text mode (runlevel 3)
shutdown graphical interface 
     $ sudo init 3
Change to text mode(tty1)
     Ctrl+Alt+F1
Verify that the Nouveau drivers are not loaded
    $ lsmod | grep nouveau
Run the installer and follow the on-screen prompts (remember that do not select NVIDIA driver which may causes login errors)
    $ sudo sh cuda_<version>_linux.run
reboot
    $ reboot

Three: Environment Setup and verify the installation

3.1 environment Setup
PATH variable
  $ export PATH=/usr/local/cuda-10.0/bin${PATH:+:${PATH}}
The LD_LIBRARY_PATH variable (64bit)
  $ export LD_LIBRARY_PATH=/usr/local/cuda-10.0/lib64${LD_LIBRARY_PATH:+:${LD_LIBRARY_PATH}}
3.2 verify the installation
  $ nvcc -V
uninstallation
  $ sudo /usr/local/cuda-10.0/bin/uninstall_cuda_10.0.pl

2>INSTALLING NVIDIA-driver

Steps one:Download the corresponding NVIDIA-driver for graphics card in https://www.nvidia.cn/Download/index.aspx?lang=cn

1.1 disabling Nouveau
  Ubuntu
    Create a file at /etc/modprobe.d/blacklist-nouveau.conf with the following contents:
     blacklist nouveau
     ptions nouveau modeset=0
  Regenerate the kernel initramfs:
      $ sudo update-initramfs -u
  reboot
      $reboot
  
     
1.2 Reboot into text mode (runlevel 3)
  shutdown graphical interface 
      $ sudo init 3
  Change to text mode(tty1)
      Ctrl+Alt+F1
  Verify that the Nouveau drivers are not loaded
      $ lsmod | grep nouveau
      
1.3 Run the installer
       $ sudo sh NVIDIA-Linux-x86_64-410.93.run -no-opengl-files
    reboot
       $ reboot
   or  $ sudo init 5 && reboot
   
    check the driver version
       $ cat /proc/driver/nvidia/version
   or  $ nvidia-smi
  
    uninstallation
        $ sudo /usr/bin/nvidia-uninstall
   or   $ sudo apt-get autoremove --purge nvidia*
