Why on a remote slave. Apps won't open on TightVnc desktop?

Question

linux

The Tightvnc server is installed on a TinkerBoard unicameral computer and screwed with crutches, so it is not advisable to remove it, however, most applications (Browser, QT Creator, VLC Player ...) do not work through it. If I understand correctly the problem is that they do not find the screen, how to capture from the screen?

Answer 1

how does it get started there? show command, script.
