Re: [Discuss-gnuradio] Output screen not stable.

[Mike Jameson]

Hi Tom,

Thanks for that. Using nongl mode has brought my wxgui back to life as I killed it after fumbling around with graphics drivers. For the record here is the error I was getting:

Xlib:  extension "GLX" missing on display ":0.0".

nongl mode also brings back a working persistence mode, yey! :)

Mike

This actually sounds more like a problem with your video card driver
in Ubuntu. I've had different results with different video cards and
drivers using Unity specifically. So try to look into that.

In the meantime, you can try turning off OpenGL support by editing (or
creating) $HOME/.gnuradio/config.conf and adding:
[wxgui]
style=nongl
