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.

Hi
I used to be able to run chimera remotely from a machine with an X- windows server (the one that comes with Cygwin in this case). But now I get the following error:
Xlib: extension "NV-GLX" missing on display "localhost:10.0".
X Error of failed request: BadRequest (invalid request code or no such operation)
Major opcode of failed request: 148 (GLX)
Minor opcode of failed request: 181 ()
Serial number of failed request: 12779

I t does work fine if run directly from the computer where chimera is installed. Any idea what the problem could be?
Thanks
