How can I check my OpenGL version?

when I run glxinfo I get:

...
direct rendering: Yes
server glx vendor string: NVIDIA Corporation
server glx version string: 1.4
...
client glx vendor string: NVIDIA Corporation
client glx version string: 1.4
...
GLX version: 1.4
...
OpenGL vendor string: NVIDIA Corporation
OpenGL renderer string: GeForce 9500M GS/PCI/SSE2
OpenGL version string: 3.2.0 NVIDIA 195.36.24
OpenGL shading language version string: 1.50 NVIDIA via Cg compiler
...

Without polling extension functionality, from what version's functions may I assume supported? Minimum of 1.4 and 3.2 seems incredibly historic, so I assume glx version is not numbered in parallel with OpenGL version...

What GLSL version may I assume? It displays the Cg compiler version, but what's my GLSL version?

GLX is the protocol that transports OpenGL commands in a X11 command stream. The most recent version of GLX is 1.4.

The OpenGL version is told in the "OpenGL version string". And you got 3.2

so I assume glx version is not numbered in parallel with OpenGL version...

No it's not, because they're two different things. GLX transports OpenGL, it doesn't implement it.

OK, basically it turns out that it is just what it says:

GLX version 1.4

OpenGL version 3.2

GLSL version 1.50 via NVIDIA Cg Compiler
