[vtkusers] Rendering to images without X (Linux)?

[Андрей Траченко]

Thank you David, I haven't seen this example before...

Unfortunately it doesn't work for me:
$ ./OffScreenRendering
ERROR: In /build/buildd/vtk-5.2.1/Rendering/vtkXOpenGLRenderWindow.cxx, line 536
vtkXOpenGLRenderWindow (0x8fb3a0): bad X server connection.
DISPLAY=ERROR: In
/build/buildd/vtk-5.2.1/Rendering/vtkXOpenGLRenderWindow.cxx, line 338
vtkXOpenGLRenderWindow (0x8fb3a0): bad X server connection.
DISPLAY=Segmentation fault

Neither works my Python script using the same idea.

Should I try a newer version of VTK? Should I try to compile it by
myself with some additional configuration?
