No screen output torizon

Hello support team

I’m currently experimenting with the new Torizon OS from you and I’m working through your quickstart tutorial. I arrived at Module 2 and at “Starting and Managing Containers with Portainer” you says under Step 1 that the Portainer login screen should be displayed after starting the module. But it doesn’t. Via web browser, I can access to the system as indicated in the example :8840. Before that, the Easy Installer was also displayed on the monitor. Is this correct? Did I something wrong?
Thank you very much in advance for an answer.

Greetings @JanP,

Just to clarify a few details. You list that you’re using Torizon 1.5.0 I assume you mean 5.1.0 correct? Also you didn’t mention this explicitly but I assume you’re using an HDMI display?

Finally is there any details about your display you could share like model, resolution, or any other special details?

Also can you SSH/serial into the device? If yes do you notice any boot logs or messages that concern the display you are using?

Best Regards,
Jeremias

@jeremias.tx

I didn´t see that you allready answered. I try that what you wrote. Thanks a lot.

Ahh okay I believe I understand now. So on the Apalis modules the default interface is HDMI, meaning VGA is disabled by default.

Though you should be able to easily enable this with a device tree overlay please see here on how to do this: Device Tree Overlays on Torizon | Toradex Developer Center

Thanks for quick answer @jeremias.tx,

I´m sorry. Of cause I´m using 5.1.0 from Torizon and no I don´t use HDMI. I use the VGA output of Evaluation Board. Its connected to a nomal lcd monitor with full hd resolution 1980x1080.

Parallel I will look to the boot log an share it here.
