[vtkusers] Python SetOffScreenRendering on Linux

[Jaco Schieke]

Does anybody have experience with SetOffScreenRendering() on the a RH Linux
platform from within the python bindings.  Using the RPMs available on the
vtk archive (vtk-3.2-3), and Mesa-3.4-13 or Mesa-4.0.1 I am unable to render
windows offscreen.  With a DISPLAY env variable set a window keeps popping
up and without it the program segfaults.  I am fairly confident that the OS
capabilities of Mesa is properly compiled into the libraries.

Does the offscreen capability require an X server to connect to?

Thanks for any help.
