'glxinfo' reports the available GLSL version.
Mesa 9.0 supports GLSL 1.30 on Gen6+.
On Mesa 9.1 and Gen6+, you get a OpenGL 3.0 context by default which supports GLSL 1.30. You can also explicitly ask for a GL 3.1 context (which isn't backwards compatible) and that will give you GLSL 1.40.
What mesa version are you using?
What does glxinfo say?
I would like to run memview [1] on my Intel HD 3000 graphic chipset. It requires GLSL 1.3, but it seems unavailable in the latest Ubuntu 13.04.
From the release notes of 2013Q1 Intel Graphic Stack Release, it's not clear what is the GLSL version supported [2]. Could it be possible add detail about supported versions with this release?
Thanks!
