I'm having this problem on an X86_64 system with Nvidia proprietary driver. In Python, I get the following errors:-

>>> import visual
>>> a=visual.box()

(<unknown>:6307): GdkGLExt-WARNING **: Cannot open P\xde\xd7\u0001

(<unknown>:6307): GdkGLExt-WARNING **: Cannot open 0\xdf\xd7\u0001

glibmm-ERROR **:
unhandled exception (type std::exception) in signal handler:
what: Unable to get extension function: glCreateProgramObjectARB even though the extension is advertised.

aborting...
Aborted

If I install the libgtkglextmm-x11-1.2-dev package as suggested, I get the following:-

>>> import visual
>>> a=visual.box()
Segmentation fault


glxgears seems to work fine. Any help much appreciated.
