armbian TV box does not start if there is no hdmi cable

Hello. I installed an armbian TV box for home automation. Everything works fine, but if the hdmi cable is removed, the TV box does not start.

It starts successfully only when the hdmi cable is inserted into the TV box.


Tv Box X96 Mini

the system is installed on a USB drive


I ran it according to this instruction https://github.com/kdrapel/x96mini_linux
