After I successfully reflashed the system using “flash.sh“, the display screen did not light up.
Then I used l4t_uefi_sign_image.sh to set the username and password and refreshed the system again, but the screen still could not light up.
Then I connected the device through the serial port, entered the terminal by entering the username and password, and set sudo systemctl set-default graphical.target.
After that, the screen lit up normally, but when I turned off the power and restarted the device again, the screen could no longer light up.
What is the reason?
Sorry, my question is just to solve the problem of how to light up the screen.
Is there any connection between this and deep learning?
My setup is jetson agx orin, here are the steps I took to re-flash the system:
- I downloaded the Driver Package (BSP) and Sample Root Filesystem to my own Ubuntu system from Jetson Linux | NVIDIA Developer
- Execute the following commands
$ tar xf Jetson_Linux_R36.4.0_aarch64.tbz2
$ cd Linux_for_Tegra/rootfs/
$ sudo tar xpf …/…/Tegra_Linux_Sample-Root-Filesystem_R36.4.0_aarch64.tbz2
$ cd …
$ sudo ./apply_binaries.sh - sudo ./tools/l4t_create_default_user.sh -u nvidia -p root123 --accept-license
- sudo ./flash.sh jetson-agx-orin-devkit mmcblk0p1
- After waiting for a while, the message “successfully” appears, and the device is restarted.
- The device is connected to the display via DP, but the display has not been lit
What should I do?
Hello,
Have you executed the command sudo ./tools/l4t_flash_prerequisites.sh? According to the official documentation, the steps are as follows:
$ tar xf ${L4T_RELEASE_PACKAGE}
$ sudo tar xpf ${SAMPLE_FS_PACKAGE} -C Linux_for_Tegra/rootfs/
$ cd Linux_for_Tegra/
$ sudo ./tools/l4t_flash_prerequisites.sh
$ sudo ./apply_binaries.sh
Additionally, I have questions for clarification:
- Is your AGX Orin a developer kit or does it use a custom carrier board?
- Is your host a ubuntu 20.04 running on a physical machine not a virtual machine(e.g. WSL, VirtualBox, VMware)
Thanks
My device is a development kit.
I ran the command on Ubuntu 20.04 on a physical machine, but I did not execute the command sudo ./tools/l4t_flash_prerequisites.sh.
I will try again.
Thanks.
I tried to follow the steps you described, but the screen still didn’t light up:
- tar xf Jetson_Linux_R36.4.0_aarch64.tbz2
- sudo tar xpf Tegra_Linux_Sample-Root-Filesystem_R36.4.0_aarch64.tbz2 -C Linux_for_Tegra/rootfs/
- cd Linux_for_Tegra/
- sudo ./tools/l4t_flash_prerequisites.sh
- sudo ./apply_binaries.sh
- Press and hold the Force Recovery button and power on the device. Wait for the white light to light up and release the button. Use lsusb to check the display: Bus 003 Device 014: ID 0955:7223 NVIDIA Corp. APX
- sudo ./tools/l4t_create_default_user.sh -u nvidia -p root123 --accept-license
8.sudo ./flash.sh jetson-agx-orin-devkit internal
After completing the above steps, the display still does not light up (I use a DP direct-connected display), so I don’t know what other solutions there are now. I wonder if you can give some suggestions, I would be grateful
By the way, I can connect to my terminal device through the serial port, and can enter the username and password to enter the terminal and type some basic commands, but I can’t light up the screen no matter what.

The log said there is no monitor connected on your Jetson. Could you try to hotplug the monitor and see if any new log shown in xorg log?
I hot-plugged the monitor’s interface, and there was no increase in the log content
Are you using a native DP monitor? or using some adapters on it?
I connected my display directly through the DP interface of the development kit via a DP to DP cable, without an adapter
-
Could you try to flash your devkit to jetpack5.1.4 and see if you can see the screen?
-
For your jetpack6.1 case, will you see the NVIDIA boot logo during the boot process?
-
Are you able to try other DP monitor on jetpack6.1 and see if you can see the GUI?
- When I used jetpack5.1.4, the phenomenon was the same as jetpack6.1.
- The screen was black all the time, and there was no nvidia icon.
- I tried to replace another DP cable and display, and the effect was the same.
However, it is worth noting that when I reflashed the system many times, I was able to enter the Ubuntu desktop twice, but after restarting the development kit, the screen did not light up.
Do you have other Jetson Orin on your side that can check if all the Jetsons there would have same issue with that screen?
I’m very sorry, I only have one baseboard, but I have two GPU core boards. Both boards cannot light up the screen.
Will the xorg log get anything new if you use a DP-HDMI adapter + HDMI monitor on your board?
But the other GPU core board was refreshed through sdkmanager. I can try it again with flash.sh.
