Tutorial on installing Nvidia graphics card driver in Ubuntu 18.04 (with pictures and text)

0. Preliminary preparation

Disable secure boot in BIOS. If it is not disabled, the graphics card driver installed using a third-party source will not be usable after installation.

1. Disable nouveau

1. Create a file. If you have not downloaded the vim editor, replace vim with gedit.

$ sudo vim /etc/modprobe.d/blacklist-nouveau.conf

2. Insert the following content into the file to add nouveau to the blacklist, which is not enabled by default.

blacklist nouveau
options nouveau modeset=0

3. Enter the following command to make the disablement effective and then restart

$ sudo update-initramfs -u
$ sudo reboot

4. Verify after restart

lsmod | grep nouveau

If there is no response after pressing Enter, the function is disabled successfully.

2. Install the graphics card driver

First completely uninstall the previously installed graphics driver:
Uninstall ppa source file:

$ sudo apt-get remove --purge nvidia*

Runfile source file uninstallation:

$ sudo ./NVIDIA-Linux-x86_64-384.59.run --uninstall

Now let me introduce the simplest installation method - ppa source driver installation to query the most suitable graphics driver version for your computer

ubuntu-drivers devices 

As shown in the figure, the best graphics driver version for my computer is nvidia-driver-435
Then install it using the command line

$ sudo add-apt-repository ppa:graphics-drivers/ppa
$ sudo apt-get update
$ sudo apt-get install nvidia-driver-435 #The number here should correspond to the version number queried above$ sudo apt-get install mesa-common-dev

Note: If secure boot is not disabled before, you will be prompted to set a password during the installation process. You will need to enter the password to disable secure boot when restarting. A blue screen will appear after restarting. At this time, you cannot directly select continue. Instead, you should press the button and select Enroll MOK. After confirmation, select continue in the next option, then enter the password set when installing the driver and start the computer.

Restart after installation is complete

$ sudo reboot

Verify in terminal after restart

$ nvidia-smi

If a GPU list appears, the installation is successful.
