Jetson orin nano DP connection not working after boot

Had a working Jetson orin nano 8GB, did some python3 version changes (possibly something else), now after reboot, not signal is sent through the DP.

What is interesting is that during boot, it does work: after plugging in the power source, it starts booting up, shows display and I see a progress bar at the bottom and the ability to enter boot settings. Then it shuts down and reboots, but without a display.

SSH works as expected, x11 forwarding shows streams, but the monitor shows “no signal from source”.

Any ideas what I can do; is it possible I just need some drivers reinstalled?
