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](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

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