those methods will work, but you dont want to download / buy / install games just to test if opengl is available, here's a more simple way.
open a console and type
glxinfo | grep vendor
what does it say ?
here's what i get
[chris@localhost chris]$ glxinfo | grep vendor
server glx vendor string: NVIDIA Corporation
client glx vendor string: NVIDIA Corporation
OpenGL vendor string: NVIDIA Corporation
which basically says, yeah, openGL for nvidia graphics cards is available.
if you have not installed accelerated linux drivers from your graphics cards company website, then you will probably be using called messa. which is basically openGL for people who dont have oenGL, it allows openGL games to work, but performance is not as good as proper OpenGL
