rviz doesn't start when run remotely, throws GLXUnsupportedPrivateRequest error

This is similar to http://answers.ros.org/question/10588/rviz-does-not-start-prints-glxunsupportedprivaterequest/ (this question), in that when I run rviz, I get the following error:

Xlib: extension "NV-GLX" missing on display "localhost:10.0". The program 'rviz' received an X Window System error. This probably reflects a bug in the program. The error was 'GLXUnsupportedPrivateRequest'.
(Details: serial 20 error_code 176 request_code 154 minor_code 16)

In my case, this happens only when I'm running rviz on my desktop while connected to it remotely, with X forwarding, using ssh -Y. When I'm at the desktop in person, rviz works just fine.

A bit more info:

I'm actually connecting to my desktop from an Ubuntu virtual machine running on a Windows laptop (I know, it's horribly baroque, but it's the only way I could get linux running on my company laptop).

This virtual machine doesn't have access to the laptop's graphics card, so it can't run rviz locally. However, I thought that it would still be able to run rviz on a remote machine, since the remote machine would do the rendering, and the laptop would just display the rendered screen images that it receives over X. Was I wrong?

The X protocol is based on remote procedure calls to the X server. X forwarding basically just means that instead of sending these commands to a local X server they are piped through a TCP socket and then processed by a local X server to display program windows. Unfortunately, this doesn't really work for OpenGL calls so you cannot run programs that require 3D acceleration using X forwarding. Have a look at VLC and VirtualGL as alternatives.

Yup, this is the cause of the problem described by OP. I've had some luck with VirtualGL and TigerVNC in the past, but it was far from easy to set up.
