Hi Marcus D. Leech,

Thank you for your response.
I never use the peak hold button on this machine because I cannot click any buttons on the screen ---- begin the program running, it is also dead as the same time. As I said before, I cannot do nothing only force quit :(

I really want to know how to fix it. On my other laptop, I do not meet this problem. And the system difference between the two computers is that I install the grc part in the laptop which met the problem.

Try setting the graphical-display rates to lower values.  In your ~/.gnuradio/config.conf file:


The defaults for those are usually 30 FPS, which your laptop may not be able to keep up with.
