title: QT wayland Failed to create display (No such file or directory)
body: <p>I am trying create a qt5 application on yocto using qtwayland.  When I run my application, the 'Apllication Output' displays this error </p>
  
  <blockquote>
    <p>"Failed to create display (No such file or directory) Application
    finished with exit code 1." .</p>
  </blockquote>
  
  <p>However, the bin file actually has successfully been deployed and I can run it on my board  by opening the file manually. I can't debug on my board,either. 
  How can I figure it out, thank you.</p>
