HDMI Screen Blank on Resume for Jetson Orin Nano

Issue Overview

Users of the Jetson Orin Nano are experiencing a blank screen issue when resuming the system from suspend mode. The problem occurs specifically during the following sequence:

1. The system is put into suspend mode using the command sudo systemctl suspend
2. The user attempts to wake up the system using the keyboard
3. Upon resume, the HDMI screen remains blank

This issue appears to be related to CPU/GPU functionality, as indicated by the system logs provided. The problem significantly impacts the user experience by preventing normal operation after a suspend cycle.

Possible Causes

1. CPU/GPU Synchronization Error: The log shows a CPU error related to the dce-fabric, which could indicate a problem with CPU initialization during resume.

2. GPU Driver Issue: The nvgpu error message suggests a timeout occurred when trying to acquire a semaphore, pointing to a potential GPU driver problem.

3. Power Management Conflict: The suspend/resume cycle may be triggering a conflict in power management between the CPU and GPU components.

4. HDMI Handshake Failure: There could be an issue with re-establishing the HDMI connection after the system resumes from suspend.

5. Firmware or BIOS Incompatibility: The system’s firmware or BIOS might not be fully compatible with the suspend/resume functionality for this specific hardware configuration.

Troubleshooting Steps, Solutions & Fixes

1. Update System Software:

   • Ensure you are running the latest version of JetPack SDK for your Jetson Orin Nano.
   • Update the system using the following commands:

     sudo apt update
     sudo apt upgrade
     

2. Check and Update GPU Drivers:

   • Verify the current GPU driver version:

     nvidia-smi
     

   • If outdated, download and install the latest GPU drivers from the NVIDIA website.

3. Modify Power Management Settings:

   • Edit the GRUB configuration file:

     sudo nano /etc/default/grub
     

   • Add the following parameter to the GRUB_CMDLINE_LINUX_DEFAULT line:

     acpi_sleep=nonvs
     

   • Update GRUB:

     sudo update-grub
     

4. Disable and Re-enable the GPU:

   • Create a script to unload and reload the GPU module after resume:

     #!/bin/bash
     echo 'Unloading NVIDIA GPU module...'
     sudo rmmod nvidia_drm
     sudo rmmod nvidia_modeset
     sudo rmmod nvidia
     echo 'Reloading NVIDIA GPU module...'
     sudo modprobe nvidia
     sudo modprobe nvidia_modeset
     sudo modprobe nvidia_drm
     

   • Save this script as /usr/local/bin/gpu-reload.sh and make it executable:

     sudo chmod +x /usr/local/bin/gpu-reload.sh
     

   • Create a systemd service to run this script on resume:

     sudo nano /etc/systemd/system/gpu-reload.service
     

   • Add the following content:

     [Unit]
     Description=Reload NVIDIA GPU modules after resume
     After=suspend.target
     
     [Service]
     ExecStart=/usr/local/bin/gpu-reload.sh
     
     [Install]
     WantedBy=suspend.target
     

   • Enable the service:

     sudo systemctl enable gpu-reload.service
     

5. Check HDMI Connection:

   • Ensure the HDMI cable is securely connected on both ends.
   • Try a different HDMI cable or port if available.
   • Test with a different monitor to rule out display compatibility issues.

6. Investigate Logs:

   • After experiencing the issue, check the system logs for more detailed error messages:

     sudo journalctl -b -1
     

   • Look for entries related to GPU, display, or power management around the time of resume.

7. Test with Default Configuration:

   • If you’ve made any custom configurations, try reverting to the default settings to see if the issue persists.

8. Verify with Developer Kit:

   • As suggested in the forum, try to reproduce the issue using the official Jetson Orin Nano Developer Kit to determine if it’s a hardware-specific problem.

9. BIOS/Firmware Update:

   • Check for any available BIOS or firmware updates for your specific hardware configuration and apply them if available.

If the issue persists after trying these solutions, consider opening a new support ticket with NVIDIA, providing detailed information about your hardware configuration, software versions, and the steps you’ve taken to troubleshoot the problem.
