Answer 1

Just run

rosrun UWSim UWSim --disableShaders

Currently, full support for shaders is possible on ATI and NVidia cards. It's possible that your integrated card doesn't support all the shaders required for UWSim. Then you have to run without shaders support, which means you will not see many of the visualization effects like silt, god rays, etc. However, all the functionality should be still there.

Please let me know if that works for you

It does work! Thank you very much!

Answer 2

Hi, what graphics card do you have? Could you please try with the --disableShaders option?

FYI: I didn't actually ask the question, just added a tag to it :-). @michaelowenliu actually asked the question.

What is the disableShaders option, and how to do with it
