In this tip, we will see how to use the command line to check which OpenGL and Nvidia driver versions are installed on your system.

Under Ubuntu 11.04/10.10/10.04, launch the Terminal (Ctrl+Alt+T) and run this command to know your current OpenGL and Nvidia driver versions:

glxinfo | grep "OpenGL version"

For Ubuntu 10.04/10.10, you need to install this package from the Terminal before running the  command given above:

sudo apt-get install mesa-utils

Here is the outpout I have got:

~$ glxinfo | grep "OpenGL version"
OpenGL version string: 3.3.0 NVIDIA 270.41.19

3.3.0 ---> This is the OpenGL version

270.41.19 ---> This is the NVIDIA driver version currently installed on my system.

That's it.
