Teamviewer Host on Raspberry Pi 4 Headless

Hoygen_83

Here is what happens on a newly made Raspberry.

We installed the system.

We installed teamviewer host and configured it to have a local password.

Case 1: there is a screen attached, we boot the system and we can login to teamviewer host, we remove the screen after boot and we can still access the host.

Case 2: the screen has been removed and the system has been rebooted, we can't access the teamviewer host.

Is there a solution you can provide for that issue?

We would like to manage the raspberries in a headless scenario.

If the pi 4 is booted without a display connected then no framebuffer/desktop is created so there is nothing for teamviewer to display.

you need to run raspi-config under display options you will find resolution.

select a suitable resolution from the list , just make sure its not the same at your actual display resolution that you have connected to the pi.
