I tried xvfb-run -s "-screen 0 640x480x24", still the same error.  Any
other clues?

ES2 Prism: Error - GLX extension is not supported
    GLX version 1.3 or higher is required
Xlib:  extension "RANDR" missing on display ":99".


Now that I run at 24 bpp, maybe I should force GLX to be enabled?  Or
have to specify a GLX version, otherwise the default is less than 1.3?
