glGetIntegerv(GL_MAJOR_VERSION, &glVersion[0]); // Get back the OpenGL MAJOR version we are using
glGetIntegerv(GL_MINOR_VERSION, &glVersion[1]); (glew)
but in glx this dont work

You have to create a GL context with glXCreateContextAttribsARB as the example shows.

If you want to make gl function calls, then you need to have a context current. Call them after the glXMakeCurrent call.
That is the way it is on all platforms (Windows, Apple, Mac and even on GL ES systems).

Or you could just use GLFW.
