could be a graphics card related issue. Can you take a look at this page (http://ros.org/wiki/simulator_gazebo/Troubleshooting) and fill in some more details as mentioned by the second half of the wiki here? Thanks.

@muin028:
Gazebo/OGRE is very sensitive regarding graphics cards and very rarely (if at all?) works with integrated graphics controllers. For Gazebo your best bet is probably an NVIDIA graphics card - I've had a laptop with an ATI card that worked but it's more of a gamble than using NVIDA I think (at least 3 years ago when I had my ATI laptop it was).

You can also check OGRE's hardware requirements, but I think you should be good with any modern dedicated graphics card: http://www.ogre3d.org/tikiwiki/tiki-index.php?page=Hardware

Btw there's a new website for Gazebo related questions: http://answers.gazebosim.org/
