What is this little black box and how do I get rid of it?

  • I built an application using Qt 5.2 for my TI AM335x EVM and it's showing a little black box (see image below). It looks like a highlighted cursor, when I touch any place on the screen it flashes. If it is a cursor.. I don't want it there (there's no mouse/keyboard with my project, just touch screen) so how do I get rid of it? I know it has to be something with how my environment is configured because more than one of my projects is showing the same little black box in the same location.

    ! Black Box on the white screen)!

    The link to your image is broken but… Aren't you seeing the login prompt blinking under your application ?

    IIRC, you need to configure your system to disable login on the tty0

    Hope it helps
