Mesa 3D graphics library 19.3 was released a few days ago. Here’s how to install it in Ubuntu 18.04, Ubuntu 19.04, and Ubuntu 19.10.

Mesa 19.3 is a big release that features:

• Intel OpenGL 4.6 support
• New Vulkan extensions both for Radeon RADV and Intel ANV
• Initial Intel Tiger Lake support
• AMD Navi 14 support (Radeon RX 5500 XT!)
• Zink is added for experimental OpenGL over Vulkan

1. Open terminal either from application launcher or by pressing Ctrl+Alt+T on keyboard. When it opens, run command:

sudo add-apt-repository ppa:kisak/kisak-mesa

Type user password (no asterisk feedback) when it prompts and read the PPA description before pressing 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 package cache.

3. Finally check your driver version via command:

glxinfo | grep "OpenGL version"

Uninstall:

To restore changes and downgrade to the default drivers shipped in your Ubuntu, run command:

sudo apt-get install ppa-purge && sudo ppa-purge ppa:kisak/kisak-mesa
