Hi Tom, Thanks much, that was exactly what was happening ! I tried with a sample rate of 250k and the window responds just fine to keyboard/mouse. That's great since I don't know much about keyboard/mouse event handling and was dreading having to debug it.
The Raspberry pi 2 has a quad core processor and as long as the flow-graph does not take more than ~25-28% CPU (one entire processor) with nothing else running the GUI window responds fine. Go above that and it stops responding. I am new to the Pi 2 and having seen this issue reported on the Pi 2 forums thought it was an obscure software bug. --Patrick ________________________________ > From: t...@trondeau.com > Date: Tue, 27 Oct 2015 10:23:23 -0400 > Subject: Re: [Discuss-gnuradio] Mouse/keyboard events not working > raspberry pi 2 > To: wp...@hotmail.com > CC: discuss-gnuradio@gnu.org > > On Mon, Oct 26, 2015 at 6:10 PM, Patrick Sathyanathan > <wp...@hotmail.com<mailto:wp...@hotmail.com>> wrote: > Hi, > > > I managed to build gnuradio from source using pybombs on a raspberry pi > 2 machine running raspbian.
