My Jetson Orin Nano Super Developer Kit fails to boot Ubuntu/JetPack 6.2 from SD card: after the NVIDIA boot splash and firmware log (see attached image), the display goes fully black except for a blinking underscore/cursor in the corner. The board remains powered up and fan runs as normal. There are no further messages, desktop, or login prompt.
Hardware & Setup:
Jetson Orin Nano Super (2025 revision)
Official NVIDIA power supply (12V/3A)
Samsung EVO 64GB and SanDisk Ultra 32GB SD cards (Class 10, U3)
HDMI connection directly to FullHD and 4K monitors (tested both)
No SSD, USB devices, or extras attached during testing
Steps Tried And Observed Behavior:
Downloaded official JetPack 6.2 SD card image from NVIDIA.
Flashed card using Balena Etcher with verification.
Inserted SD card and powered board with only HDMI, keyboard, and mouse.
Boot proceeds normally through UEFI splash/logo (see image), shows logs:
“Attempting Recovery Boot”
“EFI stub: Booting Linux Kernel…”
“EFI stub: Using DTB from configuration table”
“EFI stub: Loaded initrd from LINUX_EFI, INITRD_MEDIA_GUID device path”
“EFI stub: Exiting boot services…”
Immediately after, display becomes black and shows only a blinking “_”. No change after several minutes.
Tried multiple SD cards, HDMI cables, and monitors. All give identical result.
Waited over 10 minutes, behavior unchanged.
Confirmed power supply voltage/current is stable and official.
Here the image what i got before the black screen.

The GPU driver is fine, but the display manager (GDM/X11) fails to bind to the HDMI display at boot often due to EDID detection issues or HDMI being connected after boot.
Try to login from Macbook via USB: screen /dev/tty.usbmodem* 115200
Temporary Fix:
sudo systemctl restart gdm
This immediately brings up the login screen.
Permanent Fix:
Force HDMI output by editing /boot/extlinux/extlinux.conf and adding:
video=HDMI-A-0:1920x1080@60
at the end of the APPEND ${cbootargs} line.
2. Make sure GDM is enabled at boot:
sudo systemctl enable gdm
sudo reboot
Notes:
Freeing disk space may be required if reinstalling NVIDIA packages fails.
NVIDIA driver stack can be reinstalled using JetPack 6.x packages:
