HI Eileen,
What sort of hardware do you have? I suspect it might be a problem with
not having sufficient graphics
support<http://www.ros.org/wiki/simulator_gazebo/SystemRequirements>
.<http://www.ros.org/wiki/simulator_gazebo/Tutorials/RunningSimulatorHeadless>
What does 'glxinfo' say?
I've just updated the tutorial to run headless without the need of a
compatible GLX driver, can you give the new instructions a try?

Thank you.
