It looks like I'm missing the GLX extension for xvfb. xhost + seems to be disabling access control, xdpyinfo prints out information and doesn't seem to be being blocked (I don't know what the output should be, though), and glxinfo says "Error: couldn't find RGB GLX visual or fbconfig" and glxgears says "Error: couldn't get an RGB, Double-buffered visual". Any idea why the GLX extension isn't available and how I can get it installed? GLX is not listed in the xdpyinfo output under the extensions section. (I am running xvfb as root and my DISPLAY variable is set correctly.)

Thanks for your continued help.
