The error is that the OpenGL library is looking for a
NVidia-specific extention to the remote protocol and failing when it
is not there. That is a driver bug -- it shouldn't matter what
graphics driver you have on either of the systems. There are two
things I'd do to try and fix it: (1) try updating the NVidia driver
on the remote computer that is running chimera (not the computer
displaying chimera), and (2) try uninstalling the NVidia driver on
the remote computer, and reverting to the software implementation of
OpenGL (mesa). The first option is preferable if it works, because
the proprietary (NVidia/AMD) drivers have been faster and less buggy
than the mesa driver for most uses.<br>

Good luck,<br>
