Hello, I have done export DISPLAY=.0. Still the error exists. I have a doubt isn't it possible to display the execution of beagleboard program using usb-serial cable on my laptop???? Or is it necessary to use HDMI to DVI-D cable and connect to a monitor to execute an opencv program??? Pls help me in this regard. Awaiting your valuable response.
