I just got my NVIDIA Orin 8GB Nano. It came with Jetpack 5.1.3. I flashed it with Jetpack 6. However, after the reboot the screen is flickering. Please help!!

Hi JordanAlmond,

  1. Does changing the power supply of this monitor help this case?
  2. Could you compare the dmesg when error happens/not happens and see if anything is different?
  3. Does this monitor have other resolution? If so, could you change to other resolution and see if there is a flicker?

Thanks

Hi DavidLLL,

  1. Does changing the power supply of this monitor help this case?
    *- I’ve had the same power cord for this monitor for the past 4 years ( No flickering ever ). *
    *- I have a toggle switch which connects the same monitor ( with same monitors power supply ) to a windows machine. There’s no flicker there. *
    - When I had the Jetpack 5.1.3, there was no flicker. It started after Upgrade ( flashing ) to Jetpack 6.
  2. Could you compare the dmesg when error happens/not happens and see if anything is different?
    - The flicker is constant and happens every 5-7 seconds. could you please elaborate how I can dmesg when error happens/not happens?
  3. Does this monitor have other resolution? If so, could you change to other resolution and see if there is a flicker?
    - The monitor has PC/AV resolution and nothing else. I tried multiple ways ( including reset to factory settings ). The flicker is still there. I definitely did not see the flicker when I Jetpack 5.1.3.

Thanks

Hi,
Thank you for your response. We need additional information to proceed with the investigation:

  1. Is the device a development kit or a custom board?
  2. What type of cable are you using? Is it a DP-to-DP cable or an adapter?
  3. How are you flashing the device? Are you using SDK Manager?

Please provide the dmesg log from boot up to the point when the screen flickers. Additionally, share the logs from /var/log/xorg.0.log and the output of the lsmod command.

Thanks
David

David,
Thanks for your response.

  1. Is the device a development kit or a custom board?
    - It’s the Jetson Orin Nano Development Kit. (Amazon.com: NVIDIA Jetson Orin Nano Developer Kit : Electronics)
  2. What type of cable are you using? Is it a DP-to-DP cable or an adapter?
    - It’s just a DisplayPort ( 8K ) cable to DisplayPort 8K cable. There’s no adapter
  3. How are you flashing the device? Are you using SDK Manager?
    I flashed the device. I followed the instructions on NVDIA page. 🚅 Initial Setup Guide - Jetson Orin Nano - NVIDIA Jetson AI Lab
    - Downloaded the Balena Etcher
    *- Downloaded the Jetpack 6 *
    *- Flashed the downloaded Jetpack6 onto the microSD card using Balena Etcher. *
    - Inserted the microSD into the slot on the Developer Kit.

Please provide the dmesg log from boot up to the point when the screen flickers. Additionally, share the logs from /var/log/xorg.0.log and the output of the lsmod command.

Thanks

Hi,

Based on the log you provided, we recommend flashing the board again using our SDK Manager on a physical Ubuntu 20.04 host.
Please let us know if the issue persists after doing so.

Thanks

David,
I installed Ubuntu 20.04.6 on my machine.
Verified it
ubuntu@ubuntu:~$ lsb_release -a
No LSB modules are available.
Distributor ID: Ubuntu
Description: Ubuntu 20.04.6 LTS
Release: 20.04
Codename: focal

I then downloaded sdkmanager_2.2.0-12021_amd64.deb from NVDIA ( SDK Manager | NVIDIA Developer ).
I tried to install it using “Software Install” as well as terminal.

ubuntu@ubuntu:~$ sudo apt install ./Rupert/sdkmanager_2.2.0-12021_amd64.deb
Reading package lists… Done

Note, selecting ‘sdkmanager’ instead of ‘./Rupert/sdkmanager_2.2.0-12021_amd64.deb’
Some packages could not be installed. This may mean that you have
requested an impossible situation or if you are using the unstable
distribution that some required packages have not yet been created
or been moved out of Incoming.
The following information may help to resolve the situation:

The following packages have unmet dependencies:
sdkmanager : Depends: libcanberra-gtk-module but it is not installable
E: Unable to correct problems, you have held broken packages.
ubuntu@ubuntu:~$ sudo apt install libcanberra-gtk-module

Package libcanberra-gtk-module is not available, but is referred to by another package.
This may mean that the package is missing, has been obsoleted, or
is only available from another source

E: Package ‘libcanberra-gtk-module’ has no installation candidate

Please help!!

Before running sudo apt install ./Rupert/sdkmanager_2.2.0-12021_amd64.deb, did you execute the command sudo apt update?
Please also ensure that Ubuntu is running on a physical machine, not a virtual machine.

Thanks

Also… Should I the physical host be Ubuntu 20.04.x or can it be 24.04.x?

Hi,
Please install Ubuntu 20.04 instead.

Thanks
