Re: [Discuss-gnuradio] OpenGL running out of memory

[Marcus Müller]

Hi John,

you could try and disable OpenGL acceleration for WX Gui. That's usually
not a good thing, and it doesn't always help if your system randomly
hangs in WX things, but if it solves this:

find (or create) your ~/.gnuradio/config.conf and add

[wxgui]
style = nongl

Best regards,
Marcus
