[vtkusers] "a decent visual" error...

[Chuanxi Xu]

  Hi,everyone.I've installed VTK(first v4.0 and then v3.2) on Solaris.The 
examples can "cmake" and "make" and there's an executable generated,but it 
doesn't run well.The error was always:
  
  ${my_vtk_dir}/Rendering/vtkXOpenGLRenderWindow.cxx, line 195  
  vtkXOpenGLRenderWindow (0x36f808): Could not find a decent visual
  
  What could I do? Do I need to change any environmental variable in the topmost 
CMakeLists.txt before "cmake" VTK?
  Appreciate your attention for my urgency.
