Which of these nvidia drivers do i use? (nvidia geforce mx450) [duplicate]

Solution 1:

Ubuntu has a built-in ubuntu-drivers program that can decide automatically which graphics driver to install, and streamlines the installation of Nvidia drivers. Open the terminal and type:

sudo ubuntu-drivers autoinstall   
sudo reboot   

The autoinstall command of ubuntu-drivers installs drivers that are appropriate for automatic installation including their dependencies. In Ubuntu 20.04 and later running sudo apt upgrade not only upgrades the versions of the proprietary graphics drivers that were installed by sudo ubuntu-drivers autoinstall. Sometimes sudo apt upgrade even upgrades the proprietary graphics driver packages to more recent packages, in which case sudo apt autoremove removes the older packages which were replaced by the newer ones. For most users there's no reason to guess about which proprietary graphics driver to install, because if your system deserves a graphics driver upgrade it will get one.

The devices command of ubuntu-drivers lists proprietary drivers that are compatible with your computer's GPU. If your computer has an Intel processor and it doesn't have a discrete graphics processor, the command ubuntu-drivers devices will not return results that show that a proprietary graphics card driver is available to be installed because the Intel graphics driver is built-in in Ubuntu. Furthermore it is not necessary to uninstall any of the built-in graphics drivers because if a proprietary graphics driver is installed, Ubuntu will select it and use it automatically with the built-in graphics drivers remaining installed for possible use if Ubuntu has a problem running the proprietary graphics driver(s).

If you visit the official AMD or NVIDIA websites you will often see that the latest version of the proprietary graphics driver for your GPU is a little bit more up-to-date than the version of the same graphics driver that is available from the default Ubuntu repositories. Don't worry about this, because if the difference between version numbers of the two proprietary graphics drivers is small, then you will get similar performance by using either of the two drivers. If you install a graphics driver from the default Ubuntu repositories, you will also get automatic updates for that driver which are sometimes linked to kernel updates.

Solution 2:

Most drivers are included in Ubuntu. If you need to install proprietary drivers that can't be included in Ubuntu, then you can get them automatically from the Software & Updates application.
