Hello, I believe the problem lies with the ATI drivers, and their inability to properly support Open GL. Gazebo uses offscreen buffers for rendering, and the ATI drivers always complain about the offscreen rendering context. GLXgears works fine because it does not use offscreen buffers.
The best solution is to ditch ATI and go for Nvidia. A solution to this problem is in the works, but it will be a few more months before it's ready. -nate On 12/6/06, Joshua L.
