How do I check what OpenGL version I have under Ubuntu? Does this
help...?
$ locate libGL
/usr/lib/libGL.so
/usr/lib/libGLU.a
/usr/lib/libGLU.so
/usr/lib/libGLU.so.1
/usr/lib/libGLU.so.1.3.070701
/usr/lib/mesa/libGL.so
/usr/lib/mesa/libGL.so.1
/usr/lib/mesa/libGL.so.1.2
/usr/lib32/libGL.so
/usr/lib32/libGLU.so
/usr/lib32/libGLU.so.1
/usr/lib32/libGLU.so.1.3.070701
/usr/lib32/mesa/libGL.so.1
/usr/lib32/mesa/libGL.so.1.2
I don't know how to do it by looking at the libs. You could check
synaptic to see if newer versions are available. You can check from code
by executing glGetString(GL_VERSION), but you already did that in the
glutdemo. It returned a version string of OpenGL 1.5. So to me this
indicates you should try to update.
