It makes no sense and will confuse anyone searching for similar issues. Make sure your subject line reflect the question or problem you are having (I tired to make something up for you here based on your question). As to you questions. Those warnings you are seeing are not being generated by GNU Radio. It looks like it's something in your video driver (guessing nVidia from the name). Have you tried to start simply by just creating an application that displays something on an FFT Sink? Have you used uhd_fft to see if you can properly use the GUI at all? Tom
