[vtkusers] introduction to vtk webinar script fail

[Wright James (NHS Greater Glasgow & Clyde)]

Dear vtkUsers,

I am just beginning with VTK and watched the introduction to vtk webinar on the kitware website to get me started.

I downloaded VTK-python 6.1.0 binary for Linux and followed along with webinar using the onlinecourse_VTK6.py script. Everything ran fine until the final section on user interaction with vtkrenderwindows. On running line 202 of the script (renwin.Render()) a second openGL window was created. Then when I attempted to initialize the UI loop vtkpython crashed with the error

X Error of failed request:  BadMatch (invalid parameter attributes)
  Major opcode of failed request:  154 (GLX)
  Minor opcode of failed request:  11 (X_GLXSwapBuffers)
  Serial number of failed request:  160
  Current serial number in output stream:  160

On the webinar after calling renwin.Render() the interactive plane is drawn in the original renderwindow(), however when I run the script a second separate window is created. Does anyone know what could be the cause of this? Do I need to change any openGL settings?

I'm running 64 bit Linux, Ubuntu version 12.10

regards Jamie
