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)

depending on what you're looking for:

Open GL Implementation

You can use glxinfo, from the mesa-utils package:

sudo apt-get install mesa-utils

glxinfo | grep "OpenGL version"

Development Libraries

this depends a little,

dpkg -s [package name]

will tell you version information, etc. of any package.

but you'll need to know what specific part/implementation, etc. of opengl you're interested in. i suspect, for you, it'll be:

dpkg -s libglu1-mesa

Note: I've added this answer at a later date, because none of the existing answers address a crucial aspects regarding ssh, and will give misleading values to those who follow the above instructions.

  1. Use X-forwarding when ssh-ing. This is enabled with ssh -X.

    Without x-forwarding:

    $ ssh MYCOMP
    $ glxinfo
    Error: unable to open display
    

    With x-forwarding:

    $ ssh -X MYCOMP
    $ glxinfo | grep -i opengl
    OpenGL vendor string: NVIDIA Corporation
    OpenGL renderer string: GeForce 8800 GT/PCIe/SSE2
    OpenGL version string: 2.1.2 NVIDIA 310.44
    OpenGL shading language version string: 1.20 NVIDIA via Cg compiler
    OpenGL extensions:
    

    I should note here that this is both the wrong graphics card, and wrong version numbers. ('Wrong' in terms of what you would expect).

  2. Set DISPLAY variable to :0, to allow access to the graphic card's driver from the remote session.

    $ ssh -X MYCOMP
    $ DISPLAY=:0
    $ glxinfo | grep -i opengl
     OpenGL vendor string: NVIDIA Corporation
     OpenGL renderer string: GeForce GTX 550 Ti/PCIe/SSE2
     OpenGL version string: 4.3.0 NVIDIA 310.14
     OpenGL shading language version string: 4.30 NVIDIA via Cg compiler
     OpenGL extensions:
    

    This lists the correct graphics card (the one on the remote computer), as well as the correct version numbers.

Thanks for your effort, this is a much better answer –  jakev Sep 5 '13 at 16:29

For those who only want the version number, for example to give it in argument of a program, you can use

$ glxinfo | awk '/OpenGL version/ {print $4}'
3.0

Note: optirun glxinfo | awk '/OpenGL version/ {print $4}' if you are using bumblebee
