[vtkusers] Segmentation fault with sample applications (ATI graphics problem?)

[Mathieu Malaterre]

Hi Charlotte,

  You can easily switch to software mode rendering:

http://www.vtk.org/Wiki/VTK_OpenGL#Debugging_the_ATI_libGL

For example:

  $ export LIBGL_ALWAYS_INDIRECT=1
  $ ./my_vtk_example

If your program is running fine this way. I would suggest you try to
use a more recent fglrx driver. If this still does not work, get
someone to reimplement this buggy driver from the specs:

;)
