When starting the Orin Nano Devkit, the monitor displays “INPUT NOT SUPPORTED,” and the Jetson desktop does not appear. This issue began occurring after flashing the Devkit with the SDKManager. Do you know any solution to this problem?

Hi satou.d,

What’s your Jetpack version in use?
Are you using DP output on the devkit?

Have you tried other monitor with the same issue?
Or you would hit the issue with specific monitor ?

Please share the full dmesg for further check.

Hello,
I am using JetPack 5.1.2.
I am using DP output with an Orin Nano Devkit.
I am using a monitor made by “iiyama”, and I have also tried monitors of different models from the same manufacturer, but the same phenomenon occurs.
I will attach the message outputted by the dmesg command.

Is that a pure DP monitor or you have using something like DP-HDMI adapter?

Could you share the result of /var/log/Xorg.0.log with a monitor connected case?

Yes, I am using a pure DP monitor and not using DP-HDMI.
I will attach the file.

Are you able to see any info from your ssh with below command when monitor is connected?

export DISPLAY=:0
xrandr

Looks like this is monitor specific. Do you have other monitors to use?

I have been using this monitor for a long time, but this problem did not occur until I flashed the Devkit. I’m curious about what could be causing this issue. Does it mean that switching to a different monitor would resolve this problem?

12

Do you remember what is the version running on jetson before doing the flash?

13

Would you mind trying rel-36/jeptack6?

I was using JetPack 5.1.1.

I was hesitant about the change from Ubuntu version 20.04 to 22.04, but I think I’ll give it a try.
