Headless setup for jetson orin nano

Hello.
I am trying to access jetson orin nano’s jetpack 6 on my laptop screen through VNC viewer because i don’t have monitor available with me.
i am following this tutorial link for setup : Jetson Nano -Remote VNC Access. In this story, I will run you through… | by Bharath Sudharsan | Medium
in this link i am required to open desktop sharing panel for enabling some settings. The problem is i am able to access terminal of jetson orin nano but not able to access GUI because i am doing the VNC setup first time.
Can you please tell how can i open and change desktop sharing panel settings using terminal ?

Hi,

Hello @jankimandviya,

Just in case it might be of help, we wrote this tutorial on how to setup NVIDIA Jetson headless support using NoMachine.

Please let us know if you run into any other questions.
We would love to help.

Are you able to get it to actually run in low power mode with this as well?

I don’t mean claiming it is, I mean really running in low power mode as measured by a power meter. Currently, my testing has shown that unless you actually run with a graphical login it will not run with low power. Unfortunately, this also wastes about 1GB of memory.

Hello @KimHendrikse,

Thanks for jumping into the conversation.

Unfortunately, low power mode was not in our scope when we wrote the tutorial, we just wanted to provide a simple recipe to follow for people with no available displays. Therefore, we have never tested the solution against low power mode setting by measuring its power consumption.

I actually read your post and found it to be incredibly interesting given that that you would not actually expect low power mode to be bounded to GUI login. My best guess could be that the low power mode application only runs when there is a GUI available.

Something I would try to do is find where the power mode selection code is and then figure out what exactly changes when you interact with it and try to do it manually without the app.

Have you been able to find something different since your last comment on the post?

No I have not. Except that tegra stats shows VCC SOC to show a figure that’s more than twice as high.

Not knowing any details about how the electronics is built it’s almost like you take the load from the video away and it flows to the system. But that would be weird. But it’s five years on from the beginning of the Jetson. I would have expected this to have a well known answer.

Oh well. The power is still quite low as the screen blanks. But any opportunity to reduce power further would be very welcome for battery powered biodiversity use cases like mine in this case.
