This quick tutorial shows the steps to get a newer version of Mesa drivers on Ubuntu be it stable release or cutting-edge development release.
Mesa itself is not a graphics card like Nvidia or AMD. Instead it provides open source software implementation of OpenGL Vulkan and some other graphics API specifications for Intel and AMD graphics hardware. With Mesa you can play high-end games and use applications that require such graphics libraries.
More information on Mesa can be found in this article.
Mesa comes preinstalled on Ubuntu with the open source graphics drivers of Radeon Intel and Nvidia sometimes. Though it probably won8217t be the latest Mesa version.
You can check if your system uses Mesa and the installed versions using this command.
If for some reasons like playing games you want to install a newer version of Mesa this tutorial will help you with that. Since you8217ll be using PPA I highly recommend reading my in-depth guide on PPA.
