External monitor not working after flashing

[ashwin.nanda]

@SivaRamaKrishnaNV

I did clean flashing of DRIVE OS 6.0.10 using --clean flag and created user accounts in first login using minicom session.
I notice below display status on my target (before login into the account from GUI)

nvidia@tegra-ubuntu:~$ sudo service display-manager status
[sudo] password for nvidia:

The login screen looks like below

Dear @SivaRamaKrishnaNV these steps can be produced on working target with us, all of it. But sticking to the thread’s context here: these steps are being performed on a target that had went through a extension fuse cut off.

Therefore a clean flash and the “GUI” - gnome lock screen isnt noticed as monitor connected is always blank with orange light indicating no input signal is being sent to the monitor.

working target :

on bench which just went through power-failure as described earlier :

there are two of these with us I already have a thread mentioned about the other one here, waiting an update there too.
