Hi, Found no way to solve the problem, after trying to make openGL working and disabling as described in Tom's message so I did a clean Ubuntu 12,04 install, then run the wonderfull gnuradio installation script and now I have a nicely working waterfall with Gnuradio 3.7.2
Now, before playing time starts I have to re-install some other software ;-) Thanks, Ben 2013/11/25 Tom Rondeau <t...@trondeau.com> > On Mon, Nov 25, 2013 at 3:11 PM, Ben Z en de rest > <hoofdeigenw...@gmail.com> wrote: > > Just to update what I did to try and solve this problem (with no luck > yet) > > > > I did read that the problem could be related to the need for Python > OpenGL > > support.
