How to Check OpenGL version

Today we learn How to Check OpenGL version? OpenGL (Open Graphics Library) is a cross-language, cross-platform application programming interface (API) for rendering 2D and 3D vector graphics. The API is typically used to interact with a graphics processing unit (GPU), to achieve hardware-accelerated rendering.

How To Check OpenGL Version,

glxinfo | grep "OpenGL version"

You will get the output as follows,

glxinfo | grep "OpenGL version"
OpenGL version string: 1.4 (2.1 Mesa 7.7.1)

Edit:

You may have better luck with modern OpenGL just grepping for “version” instead of “OpenGL version” given the differences between the core and compat profiles, as well as the various GLSL and GLES versions:

glxinfo | grep 'version'
server glx version string: 1.4
client glx version string: 1.4
GLX version: 1.4
    Max core profile version: 4.1
    Max compat profile version: 3.0
    Max GLES1 profile version: 1.1
    Max GLES[23] profile version: 3.0
OpenGL core profile version string: 4.1 (Core Profile) Mesa 11.1.2
OpenGL core profile shading language version string: 4.10
OpenGL version string: 3.0 Mesa 11.1.2
OpenGL shading language version string: 1.30
OpenGL ES profile version string: OpenGL ES 3.0 Mesa 11.1.2
OpenGL ES profile shading language version string: OpenGL ES GLSL ES 3.00

Notice that the actual version is presented by the “core profile version” (4.1), whereas the “OpenGL version” is presented as 3.0.
