Mesa is an open source 3D computer graphics library that provides a generic OpenGL implementation for rendering three-dimensional graphics on multiple platforms.

• Mesa provides open source software implementation of OpenGL, Vulkan, and some other graphics API specifications for Intel and AMD graphics hardware.
  • Mesa implements various API’s (Application programming interface) like OpenGL, OpenGL ES, OpenCL, OpenMAX, VDPAU, VA API, XvMC and Vulkan.
• With Mesa, you can play high-end games and use applications that require such graphics libraries.

Determine whether 3D acceleration is working:

glxinfo  | grep rendering

returns:

direct rendering: Yes

The output should be: direct rendering: Yes.
