I'm using X11 on my Mac OS X to remotely access our Linux machine.  When I try and open Tkmedit I get the following error:

freeglut (/usr/local/freesurfer/stable/bin/tksurfer.bin): OpenGL GLX extension not supported by display 'localhost:10.0'

I've tried using Chicken of the VNC and VNCViewer to remedy this but I still have the same problems.

Does anyone know what I should do to fix this?

Thanks,

Lauren
