How to Install Mesa 19.3 in Ubuntu 19.10

How to install Mesa 19.3 in Ubuntu Linux. Mesa is an open-source implementation of the OpenGL specification. OpenGL is a programming library for writing interactive 3D applications.

The Mesa project began as an open-source implementation of the OpenGL specification – a system for rendering interactive 3D graphics.

Over the years the project has grown to implement more graphics APIs, including OpenGL ES (versions 1, 2, 3), OpenCL, OpenMAX, VDPAU, VA API, XvMC and Vulkan.

A variety of device drivers allows the Mesa libraries to be used in many different environments ranging from software emulation to complete hardware acceleration for modern GPUs.

Mesa ties into several other open-source projects: the Direct Rendering Infrastructure and X.org to provide OpenGL support on Linux, FreeBSD and other operating systems.

Hardware-accelerated OpenGL implementations are available for most popular operating systems today. Still, Mesa serves at least these purposes:

  • Mesa is used as the core of the open-source X.org DRI hardware drivers.
  • Mesa is quite portable and allows OpenGL to be used on systems that have no other OpenGL solution.
  • Software rendering with Mesa serves as a reference for validating the hardware drivers.
  • A software implementation of OpenGL is useful for experimentation, such as testing new rendering techniques.
  • Mesa can render images with deep color channels: 16-bit integer and 32-bit floating point color channels are supported. This capability is only now appearing in hardware.
  • Mesa’s internal limits (max lights, clip planes, texture size, etc) can be changed for special needs (hardware limits are hard to overcome).

Mesa 19.3.0

Mesa 19.3.0 implements the OpenGL 4.6 API, but the version reported by glGetString(GL_VERSION) or glGetIntegerv(GL_MAJOR_VERSION) / glGetIntegerv(GL_MINOR_VERSION) depends on the particular driver being used. Some drivers don’t support all the features required in OpenGL 4.6. OpenGL 4.6 is only available if requested at context creation. Compatibility contexts may report a lower version depending on each driver.

Mesa 19.3.0 implements the Vulkan 1.1 API, but the version reported by the apiVersion property of the VkPhysicalDeviceProperties struct depends on the particular driver being used.

Install Mesa 19.3 in Ubuntu

sudo apt-get update
sudo add-apt-repository ppa:kisak/kisak-mesa
sudo apt-get dist-upgrade
sudo apt-get update

Once installed, check the version of Mesa in Ubuntu System:

glxinfo | grep "OpenGL version"

Note that Mesa 19.3.0 is a new development release. People who are concerned with stability and reliability should stick with a previous release or wait for Mesa 19.3.1.
