glxinfo:
OpenGL vendor string: NVIDIA Corporation
OpenGL renderer string: GeForce 9600 GT/PCI/SSE2/3DNOW!
OpenGL version string: 2.1.2 NVIDIA 173.14.22

glxinfo | grep 3D
OpenGL renderer string: GeForce 9600 GT/PCI/SSE2/3DNOW!
    GL_EXT_stencil_two_side, GL_EXT_stencil_wrap, GL_EXT_texture3D, 

But then again:
