 Siva,

When posting a new question on the mailing list, please do not respond 
to
the daily digest. 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?
