Re: [Discuss-gnuradio] WX GUI Scope frozen and error-msg gr_vmcircbuf_default_factory: Invalid argument

Tom,

that was a good first shot:

I created ~/.gnuradio/config.conf with the lines:

[wxgui]
style = nongl


I even tried

[wxgui]
style = nogl

not any difference

Then I renamed C:\Python27\Lib\site-packages\PyOpenGL-3.1.0a1-py2.7.egg-info
to
C:\Python27\Lib\site-packages\PyOpenGL-3.1.0a1-py2.7.egg-info_nope

and renamed C:\Python27\Lib\site-packages\OpenGL
to
C:\Python27\Lib\site-packages\OpenGL_nope

and that helped a lot.
I got a moving display on the scope finally.

In my command window now I get the following message:

What OS are you using? What version of GNU Radio?

You can try the old trick of disabling OpenGL. Make and edit
~/.gnuradio/config.conf and add the lines:

[wxgui]
style = nongl


Your error looks more involved than that, but it's possible this will
fix it anyways.
