When I run the qt example app "texture"(actually any gui program) from the ssh login, there will be an error: Failed to create display (No such file or directory).
I found that weston running on tty7, if I stop weston: systemctrl stop weston,
and then run the command: weston --tty=[1~7] &, the qt example works fine.
So how to configure the init weston run correctly?
weston.service:
