The gl functions go into glapitemp. Then they jump to the noop
versions of the functions. This is controlled by the dispatch table. 
So something is wrong with the dispatch mechanism for local users of
the gl entry points.

Somewhere there must be a dispatch table for remote GLX calls versus
the local ones. My guess would be that neither of these are getting
activated and you are just defaulting into the all noop one. It is not
clear to me if the noop dispatch table being hit is generated from the
mesa library or GLX code.
