    I run the simple example in debian OS only.
    After this,I copied this exe file in my beaglebone ,
    And connected that beagleboneboard to display touch screen,
    Now executing that exe file in beaglebone(via ssh debian@192.168.7.2)

    But getting the error

    Qxcb connection :could not connect to the display..

    Can anyone please ,suggest me what mistake I am doing,how do I solve this problem...

    @Asha Do you have X11 running on your device? Connecting display is not enough...
