Re: [Discuss-gnuradio] Controlling USRP remotely using VNC

[Josh Blum]

This is probably an issue with controlling OpenGL remotely using VNC. 
And on some machines it works, and on some it does something wrong. If 
you figure it out let me know!

In the meantime, you can disable the opengl graphical displays and it 
will revert to the non-gl ones which should definitely work over VNC.

Do this, except style=nongl:
