Lanturn uses the Nvidia Jetson TX2 Module connected to the carrier board (P2597) that comes with the Nvidia Jetson TX2 Developer Kit. However, in the future, the carrier board will be switched out with a Quasar Carrier Board.

To flash, back up and upgrade the software in the TX2, download the Nvidia SDK Manager

Lanturn has a Fathom-X onboard, which can be used to establish a connection with another computer.

To SSH into the TX2, auto login needs to be enabled.

The assumption is that the TX2 is using gnome display manager.

Configure automatic login through gsettings or by editing the /etc/gdm3/custom.conf file.

# make a back up of the /etc/gdm3/custom.conf file
sudo cp /etc/gdm3/custom.conf /etc/gdm3/custom.conf.bak

# edit the /etc/gdm3/custom.conf
sudo nano /etc/gdm3/custom.conf

Add the configuration for automatic login.
