[Discuss-gnuradio] Mouse/keyboard events not working raspberry pi 2

[Patrick Sathyanathan]

Hi,


I managed to build gnuradio from source using pybombs on a raspberry pi 2 
machine running raspbian. It took many tries and the build itself took a day 
and only worked after increasing the swapfile size to 2GB. 


I am able to run osmocom_fft at 2.4Msps sample rate with an rtl-sdr dongle 
plugged in. However, the window does not respond to keyboard or mouse 
interactions. I unable to change the frequency in the text box. Nor can I move 
the slider. I have verified that gnuradio-companion works fine and accepts 
mouse/keyboard inputs. However, flowgraphs generated using GRC do not accept 
mouse/keyboard.


Any idea what the problem could be ? If I switch to other windows when 
osmocom_fft is running the keyboard/mouse work just fine. I am using a wireless 
mouse and keyboard that share a single usb dongle.


Thanks for any help,
