For Ubuntu 18.04 users sticking to open-source graphics drivers, the latest Mesa 18.1.3 graphics library now is available to install via X-Updates PPA.

Mesa 18.1.3 was released a few days ago with several fixes to the RADV Vulkan driver, Meson and Autotools build systems updates, fixes within the common NIR and GLSL compiler code paths, a few Intel driver fixes, and more.

To enjoy some Linux games while using the open source RadeonSI / RADV / Intel / Nouveau drivers, you may follow below steps to install Mesa 18.1.3 in Ubuntu 18.04:

1. Open terminal either via Ctrl+Alt+T or by searching for ‘Terminal’ from software launcher. When it opens, run command:

sudo add-apt-repository ppa:ubuntu-x-swat/updates

Type your password (no asterisks feedback while typing) when it prompts and hit Enter to continue.

2. After adding the PPA, do system update via command:

sudo apt-get dist-upgrade

apt-get update is not required any more in Ubuntu 18.04 since adding PPA automatically refreshes system repositories.

3. Finally check your driver version via command:

glxinfo | grep "OpenGL version"

Uninstall:

To restore changes and downgrade to the default drives shipped in Ubuntu 18.04, run command:

sudo apt-get install ppa-purge && sudo ppa-purge ppa:ubuntu-x-swat/updates
