My method come from this post: https://forum.qt.io/topic/50228/solved-qtwebengine-headless.
I have test it use terminal under ubuntu with GUI, but it will output the same error as yours when I switch to text interface with CTRL+ALT+F1. I am sorry, and I am confused.

Do not call show() member function of widgets, the application will become a console application.

I have a server running linux with no active display. When I try to run a program that calls qt web engine, I get this error:

QXcbConnection: Could not connect to display 

The only way I can get it to run is by installing xvfb (X virtual frame buffer), and then running:

xvfb-run -s "-screen 0 640x480x16" ./myProgram

However, xvfb introduces additional complexity when it comes to debugging (such as if an xvfb server hangs, all subsequent request will silently hang as well), and I would like to know if there is a way I can get around to not use it.

I know we can run WebKit completely headless because I can use the same linux server with no active display to run phantomjs just fine, and it doesn't produce any display errors. So I was wondering, is there a way I can run qt web engine completely headless as well?
