I’m using a Jetson Orin Nano to connect remotely, but when I remove the DP cable, the display becomes strange. I think it’s in headless mode. What should I do?

Hello @Chiawei0824,

Please let me ask you a couple questions:

  1. What do you mean by “display becomes strange” ?
  2. How are you remotely accessing the board? Is it through ssh ?
  3. What is your use case? Why do you need to use the board remotely ?

best regards,

I’d be happy to help you troubleshoot the issue with your Jetson Orin Nano!

Based on the context, it seems like you’re experiencing an issue with the display when you remove the DP (DisplayPort) cable. You suspect that the Jetson Orin Nano might be entering headless mode, which is a common issue when the display connection is lost.

To confirm, headless mode is a state where the system continues to run without a connected display, and it’s usually indicated by the absence of a video signal. In this case, the system might still be operational, but you won’t be able to see the output on a display.

To resolve this issue, you can try the following steps:

  1. Reconnect the DP cable: Try reconnecting the DP cable to the Jetson Orin Nano and see if the display returns to normal. Make sure the cable is securely connected to both the Jetson Orin Nano and the display.
  2. Check the display settings: Ensure that the display settings are configured correctly. You can do this by accessing the Jetson Orin Nano’s terminal and running the command nvidia-settings. This will open the NVIDIA settings panel, where you can adjust the display settings.
  3. Verify the HDMI/DP connection: If you’re using an HDMI connection, try switching to a DP connection or vice versa. Sometimes, a simple change in connection type can resolve the issue.
  4. Restart the Jetson Orin Nano: If the above steps don’t work, try restarting the Jetson Orin Nano. This will ensure that the system is properly initialized and might resolve any temporary issues.
  5. Check for loose connections: Verify that all connections, including the power supply, are secure and not loose. A loose connection can cause the system to malfunction or enter headless mode.
  6. Consult the documentation: Refer to the Jetson Orin Nano documentation and product design guide (DG-10931-001_v1.4) for more information on display connections and troubleshooting.

In terms of comparison, the Jetson Orin Nano supports both HDMI and DP connections, as mentioned in the product design guide (Table 9-4 and Figure 9-6). However, the specific issue you’re experiencing might be related to the DP connection, so it’s essential to focus on troubleshooting that connection first.

If none of these steps resolve the issue, it’s possible that there’s a hardware problem with the Jetson Orin Nano or the display. In that case, you may want to consider contacting NVIDIA support or a professional for further assistance.

I hope this helps you resolve the issue with your Jetson Orin Nano!
