        Did you redirect the output as @Pablo-J-Rogina suggested before?
        If so then do not redirect, just make sure you see graphical desktop on the display.

            @Asha Can you connect a keyboard to your device and start your app directly on the device without SSH?

                  Because you seem not to forward the X display through the SSH connection.

                  how do I execute it by laptop?

                  I've already told you, see one of my previous posts.
                  In addition, you may want to read more about X forwarding, there's plenty of articles, for instance here. I won't post anymore about this issue remote display.

                    I told him to not to do so because he wants to see the application on display connected to the device, not on the host.

                      So it seems he's finally able to run the Qt app from the device. But he still insists as:

                      but why not getting by the laptop(via ssh)?

                      so indeed he's driving us crazy as he doesn't know what his requirements are... and we're trying our best to help him. Anyway.
