No signal from display port

I have no signal from the display port.

Earlier I tried to login to my profile and it wouldn’t let me in eventhough I definately had the correct password. It would just take me back to login screen. So I restarted it. Now the display is not working. I tried force recovery mode, still nothing. I also tried a different HDMI display.

What should I do?

Based on the provided context, it appears that you are experiencing issues with your Jetson AGX Orin’s display port and login functionality. Here’s a step-by-step guide to help you troubleshoot and potentially resolve the issue:

  1. Display Port Issue:
    • Since you’ve tried a different HDMI display and still encounter no signal, the issue might be with the Jetson AGX Orin’s display port or the HDMI-to-DisplayPort adapter (if used).
    • Refer to the “DisplayPort#” section in the provided context, which outlines the verification steps for DisplayPort on Jetson AGX Orin. Ensure that your display is compatible with the Jetson AGX Orin’s DisplayPort specifications.
    • Try using a different DisplayPort cable or adapter to rule out any issues with the current one.
  2. Login Issue:
    • The login issue you experienced earlier, where you were unable to log in despite entering the correct password, might be related to a system or software issue.
    • Since you’ve restarted the system and the issue persists, it’s possible that there’s a problem with the system’s configuration or software.
    • Try booting the system in recovery mode (as you’ve already done) and see if you can access the system’s terminal or command line. If you can, try running some basic system checks, such as sudo apt update and sudo apt upgrade, to ensure that the system is up-to-date.
  3. Force Recovery Mode:
    • You’ve already tried force recovery mode, but it’s essential to ensure that you’ve followed the correct procedure. Refer to the “UART Access” section in the provided context for instructions on accessing the UART console.
    • If you’re still unable to access the system, try using a different UART console or a serial console cable to rule out any issues with the current setup.
  4. Comparison with Similar Issues:
    • The provided context mentions several issues related to Jetson AGX Orin and display ports. While your issue seems unique, it’s essential to compare and contrast with similar problems to identify potential solutions.
    • For example, issue 4618846 mentions a problem with a specific DP-to-HDMI converter. Although your issue is not exactly the same, it’s possible that a similar solution might work for you.

To further assist you, I would like to ask a few questions:

  1. Have you made any recent changes to the system’s configuration or software?
  2. Are you using a specific display or adapter that might be causing the issue?
  3. Have you tried booting the system in safe mode or with a minimal configuration to isolate the problem?

Please provide more information about your setup and the steps you’ve taken so far. This will help me provide a more accurate and comprehensive solution to your problem.
