DGX Spark hangs on boot

Has been happening from yesterday after i took some help from chatgpt to install some broken nvidia drivers to fix nvidia-smi

Does it stay on this screen? Can you still ssh into the system?

Yes. It just stays om this screen. And yes. I am able to access via nvidia sync on wifi

Check what target the system reached

systemctl get-default
systemctl status multi-user.target graphical.target
systemctl --failed

If multi-user.target is active and graphical.target is not, then it’s stuck before GUI.

Check the display manager

systemctl status display-manager
journalctl -b -u display-manager --no-pager | tail -80

Quick test: sudo systemctl restart display-manager

Make sure a TTY login exists on the console

sudo systemctl status [email protected]
sudo systemctl restart [email protected]

If that starts cleanly, try on the physical machine, if the keyboard works

Ctrl + Alt + F1F6 to switch TTYs and see if a login prompt appears.

Look for serious boot errors

journalctl -b -p err..alert --no-pager | tail -100
dmesg | tail -80
dmesg | grep -i xhci | tail -40

collect also

systemctl --failed
systemctl status display-manager
journalctl -b -u display-manager --no-pager | tail -60

I just reset everythint back to factory settings
