How to Install Mesa 17.1.0 via PPA on Ubuntu Desktop

   Mesa 17.1.0 implements the OpenGL 4.5 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 4.5. OpenGL 4.5 is only available if requested at context creation because compatibility contexts are not supported.


Mesa 17.1.0  New features
  • OpenGL 4.2 on i965/ivb
  • GL_ARB_gpu_shader_fp64 on i965/ivybridge
  • GL_ARB_gpu_shader_int64 on i965/gen8+, nvc0, radeonsi, softpipe, llvmpipe
  • GL_ARB_shader_ballot on nvc0, radeonsi
  • GL_ARB_shader_clock on nv50, nvc0, radeonsi
  • GL_ARB_shader_group_vote on radeonsi
