Dear @sunjiandong,
Could you flash the board again with sdkmanager and see it fixes the issue?

@sunjiandong
Please also confirm if Finalize DRIVE AGX Orin System Setup was followed.

Dear @VickNV,

I have the same issue, after the reboot the display stays black. gdm3 is running.

I might have issues with “Finalize DRIVE AGX Orin System Setup”. During the installation via putty (/dev/ttyACM0) I do not get the request. At which point during the installation do I need to connect via putty?

The output after the installation is following:

Please try if changing a monitor as the developer.

Dear @VickNV! Thanks for your help! Via ssh I figured out that the platform runs like expected. In the end the HDMI cable was broken. Sorry, I did not check the cable, because it worked with the PC. But now everything is fine.

Good to hear you figured out the problem.
