How can I find out my OpenGL version on Ubuntu 13.04

Question

Does this question even make sense?

SFML 2.0 has added a feature whereby you can specify an OpenGL version to use. Is there a terminal command I can run (or otherwise) to find out what version I should be using?

Answer 1

To know your OpenGL version in Ubuntu,

Install Glxinfo

$sudo apt-get install mesa-utils

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)
