Unable to run Xhost + on Jetson NX headless

[byronr]

Hi I’ve been discussing with Nvidia’s technical folks on a potential workaround for running Jetson NX headless by creating a virtualized display target. Can you please confirm if the below workaround will work for Jetson NX? Thanks!

What is the best way to control the jetson Orin GUI remotely?

Sorry, we haven’t verified kind of this dummy display port adapter. For your use case, you might could refer to the following steps to enable virtual display for VNC. Step 0: Enable Screen sharing through connecting monitor first Settings → Sharing → Screen Sharing → set ‘Active’ Step 1: update and install xserver-xorg-video-dummy $ sudo apt update $ sudo apt install xserver-xorg-video-dummy Step 2: Create config for dummy virtual display $ cd /etc/X11 $ sudo vim xorg.conf.dummy Step3: …

Hi byronr,

Do you work with user133662?

Are you using the devkit or custom board for Orin NX?
What’s your Jetpack version in use?

The method in your link have been verified on R35 and should work for different platform. You could just refer to those steps to configure VNC on your board.

I’m not familiar with user133662. The Orin NX is a custom board from Hadron carrier: https://connecttech.com/product/hadron-carrier-for-nvidia-jetson-orin-nx/

Jetpack version installed is 5.1.2.

We’re still struggling to target the display using “xrandr” and “xhost +” commands with the above steps.

It seems you are using the custom carrier board.

Have you finished the Setting Up VNC | NVIDIA Developer before above steps?

Please share the full commands you used to configure VNC on your board.
Is there any error showed in any step?

We have followed the steps in Setting Up VNC | NVIDIA Developer

Here is the output. How would we attempt to connect to the vnc server now?

Please check the ip address from your board and use VNC viewer from your host PC to access your board.
