Note. Before downloading and installing new driver, make sure that your system has a supported NVIDIA GPU. You can also use automatic scanning, contacting the Drivers section on the website of NVIDIA to find the latest drivers for your NVIDIA GPU.
How to identify and install the correct driver for your Nvidia video card in Linux Mint can be viewed on page "How to detect and install the correct version of the Nvidia driver on Linux Mint". Otherwise, after you install the NVIDIA driver 387 you risk not to run the system.
Installation latest version into Linux Mint:
If you not previously added repository to the system
Afetr, you can set in the driver Manager
sudo add-apt-repository ppa:graphics-drivers/ppa sudo apt update
After the installation, restart the computer to activate this driver.
sudo apt install nvidia-387 nvidia-settings
After a new logon check the installed graphics driver utility NVIDIA X Server Settings, search in the menu or in the terminal command:
If you installed a new kernel, it is possible to even reconfigure the kernel module with the new driver. To do this, run the following command in the terminal:
glxinfo | grep OpenGL
In the case when in the terminal you will see the impossibility of reconfiguring the kernel module with the new driver, it is better to stop using it, otherwise you may get black screen after restarting the computer, i.e. the system will be inoperable.
sudo dpkg-reconfigure nvidia-387
How to get out of the situation "black screen", see "black boot screen after installing video driver".
May the Force be with you,
