Wxgui strange problem

Hello all,

I just freshly installed Xubuntu 11.10 and installed Gnuradio with the
build_gnuradio script with out any problems. When I use uhd_fft.py or
any
program that uses the FFT sink ( all other sinks work ) I get a very
strange problem, as long as some part of the FFT plots line is hidden it
will run with no problems, but a soon as I change a parameter which
results
in the showing of the entire blue line from start to finish it crashes
with
no errors ( just falls back to prompt quietly ). I can change the gain
so
the line comes up into view and when it does it crashes, I can also
scale
the plot down until the line is completely shown or scale up to the line
or
even just change to a frequency with a higher noise level, the result is
the same, if the line is completely on the screen it crashes. I’m not
sure
where to start with this one, I don’t know if it’s in Wxgui or WX
itself,
or something with my system. How should I start finding the problem?

Thank you all. http://www.sbrac.org/files/build-gnuradio

Andrew -

It would probably be helpful if we could confirm that someone else with
the
same setup sees the same issue.

What versions of of the WX libraries and development packages do you
have
installed? What checkout of GNU Radio do you have? What about the
relevant Python packages?

Cheers,
Ben

I know there are people using the latest Gnu Radio (from fresh GIT) on
regular Ubuntu 11.10, so I wonder if there’s a library difference
somewhere (WxPython, WxGUI, Xlib, etc) that is causing this?

What are the major differences between the XUbuntu “roll” and the
regular Ubuntu “roll”.
