imx8mq+yocto_4.9.51 Qt examples run failed problem

[传策薛]

Hi community:

   when I run the qt examples by: ./xx

returns :"Running on a compositor with no screens is not supported", what should I do?

Hello,

Probably, you do not have any display assigned. Can you please try using the below Linux command and test again?

$ export DISPLAY=:0

Best regards,

Diego.
