Jetson nano won't wake up from sleep

stm32h757 · September 15, 2025, 12:45pm

Hi,

I’m using a Jetson Nano with a fresh install of Ubuntu 20.04.
Whenever the system goes into sleep, it never wakes up again — the screen just stays black.

I already checked the settings, and Automatic Suspend is disabled, so I don’t think it’s caused by that.
I also noticed another issue: the NVIDIA logo at the top-right corner looks stretched and broken.

Is this a known issue with Jetson Nano and Ubuntu 20.04?
How can I prevent the system from going black and not waking up?

Thanks in advance

Hi stm32h757,

Are yo using the devkit or custom board for Jetson Nano?
What’s the Jetpack version in use?

As my understanding, Jetson Nano supports 18.04(in Jetpack4.x) rather than 20.04.
How did you update Jetson Nano to Ubuntu 20.04?
Please share the result of the following commands for further check.

$ cat /etc/nv_tegra_release
$ cat /etc/nv_boot_control.conf

Hello.

Thank you for your reply.

1.Devkit or Custom Board :

I’m using the official Jetson Nano, I have used the Jetson TK1, but I’m still beginner, so I kindly ask for your patience.

I’m also using AC8265 NGW Wi-Fi card with the Jetson Nano.

2.Why I’m using Ubuntu 20.04 :

Yes, Jetson Nano supports up to Ubuntu 18.04.

However, I heard that ROS2 is not supported on 18.04.

If the version is the problem, I’m willing to roll back to 18.04.

3.How I updated Jetson Nano to Ubuntu 20.04 :

I first flashed Jetpack on Jetson Nano following official guide and below guide :

github.com/dnovischi/jetson-tutorials

jetson-nano-ubuntu-18-04-install.md

main

# Jetson Nano Ubuntu 18.04 Full Install

This install guide assumes that the setup will done via an Ubuntu enabled PC with access to root privileges.\
The Jetson Nano setup will proceed in headless mode.\
I recommend using an endurance SD Card UHS U3, V30 or higher, Class 10.

1. The official intro to the board can be found [here](https://developer.nvidia.com/embedded/learn/get-started-jetson-nano-devkit#intro).
2. To power the Jetson Nano get a power supply that can delliver (at least) 3A at 5V that has:
  - 2.1 Barel Jack output for Jetson Nano B01 or higher
  - USB-C Type output for Jetson Nano A02
3. To configure the Jetson Nano to be powered via the 2.1 barel jack connector you'll need to have a jumper.
4. To connect to the Jetson Nano in headless mode you will need a micro USB cable.
5. Download the latest official Nvidia image from [here](https://developer.nvidia.com/jetson-nano-sd-card-image)
6. Install Balena Etcher on your Ubuntu PC by following the instructions [here](https://github.com/balena-io/etcher#debian-and-ubuntu-based-package-repository-gnulinux-x86x64)
7. Plug-in your micro SD Card into the PC
8. Fire up Etcher, chose the image you downloaded in step 4 and select your micro SD Card as the target (e.g. /dev/mmcblk0).
9. Click Flash, enter the root password and let Etcher do its thing.
10. Unmount the SD Card from the PC.
11. To check if the SD Card is properly umounted do the following:

and I updated it to 20.04 following below guide :

# Jetson Nano Ubuntu 20.04 Install Through Distribution Upgrade

This tutorial details the steps necesarry to upgrade the official Ubuntu 18.04 Jetson Nano image to Ubuntu 20.04. This setup assumes you already have a clean Ubuntu 18.04 installation that is fully updated. If you don't, please follow the  [Jetson Nano Ubuntu 18.04 Full Install](jetson-nano-ubuntu-18-04-install.md).

Please note that NO librealsense SDK, ROS, Pytorch, TensorFlow or any other framework should have been previously installed. This is because all frameworks have many dependencies which can't be satisified during the distribution upgrade. In all likelihood, you'll end up with a broken OS.

1. First, let's remove some of the packages that cause problems:

```bash
sudo apt-get remove --purge chromium-browser chromium-browser-l10n
```

2. Update and upgrade:

```bash
sudo apt-get update;sudo apt-get upgrade -y
```

3. If durring the upgrade you encounter an error about the nvidia-l4t-bootlader do the following:
```bash

5. Things I have done to my jetson nano :

So far, I have only installed Zero-tier and mediamtx.exe.

Hello. Do I have to roll back to 18.04?

KevinFFF · September 24, 2025, 2:28pm

It seems the guide is from 3rd-party GitHub and we’ve not verified it.

From the result you shared, it is L4T r32.7.6 (which is part of Jetpack 4.6.6).

Could you also share the result of uname -r on your board?

Since you are using the devkit, we would suggest referring to the following instruction to use SDK manager to flash fresh Jetpack 4.6.6 to verify if there’s still wake up failed issue.
Install Jetson Software with SDK Manager — SDK Manager

Below is the result of uname -r, I will use 20.04 for some reason, and I changed Blank Screen option to Never. Thank you

KevinFFF · October 2, 2025, 6:09am

K4.9 reported by uname -r should be from Ubuntu 18.04.
For Ubuntu 20.04, the kernel should be K5.4 or K5.10.

stm32h757 · October 13, 2025, 12:44am

although the issue isn’t fully resolved, I’ll continue using this version for now. Kernel updates seem a bit uncertain to me, and it’s difficult to do a fresh install since I already have important project files on this system.

Even after changing the “Blank Screen” option to “Never”, the problem still persists.
