Hi Marcus,

Thank you for your patience with my CtrlPort Performance Monitor problems. I 
have been distracted by other projects and finally had time to try your 
suggestion.

Here is the terminal output from running gr-perf-monitorx:

address@hidden:~/gnuradio/prefix/perfmon$ gr-perf-monitorx vmware 46263
QPaintDevice: Cannot destroy paint device that is being painted
Traceback (most recent call last):
  File 
"/home/jim/.local/lib/python2.7/site-packages/matplotlib/backends/backend_qt5agg.py",
 line 72, in paintEvent
    painter.drawImage(origin / self._dpi_ratio, qimage)
  File

 line 273, in _dpi_ratio
    return self.devicePixelRatio() or 1
RuntimeError: wrapped C/C++ object of type FigureCanvasQTAgg has been deleted
Segmentation fault (core dumped)

Does this give you any ideas about what is causing the blank Performance 
Monitor graph display?

Regards,
