Step 1: Removing GUI
Disk space regained in typical setup by removing GUI

|---|---|---|---|
| 1. Removing GUI | 3.4 GB | 3.3 GB | 3.2 GB |
You can remove some of the packages included in the base BSP, L4T/Jetson Linux. There are some productivity applications like LibreOffice suite and Thunderbird email client (and they take up more than 200MB as seen in the previous section), you can safely remove them.
You can even remove ubuntu-desktop if you know your system does not require GUI on Jetson’s native display output (via HDMI, DP/eDP, or LVDS).
Commands to Copy for Removing GUI
Uninstalling packages only found in "desktop" package list.
Download nvubuntu-bionic-packages_only-in-desktop.txt.
sudo apt-get update
sudo apt-get purge $(cat nvubuntu-bionic-packages_only-in-desktop.txt)
sudo apt-get install network-manager
Download nvubuntu-focal-packages_only-in-desktop.txt.
sudo apt-get update
sudo apt-get purge $(cat nvubuntu-focal-packages_only-in-desktop)
sudo apt-get install network-manager
Warning
Make sure to install network-manager back (or not to remove in the first place).
Removing network-manager and rebooting will result in having the network interface (eth0) not up the next time the system boots up, so you won't be able to remotely SSH into it.
Re-installing JetPack Components
sudo apt install nvidia-jetpack
sudo apt clean
sudo rm -rf /var/cuda-repo-l4t-10-2-local
The above *_only-in-desktop.txt file is derived by subtracting the minimal package list from the full/desktop package list for rootfs that you can find them in L4T Flashing Tool. The minimal package list does not include essential build tools like “build-essential”, so it would remove some of the JetPack components if they have dependencies on them.
So you would need to perform the following to make sure you have everything of JetPack components.
And if you start from the base BSP (Configuration: [a]), with above commands you only get to the minimal L4T configuration (Configuration: [b]), so you want to install the JetPack components anyway to get to “Full JetPack without GUI” configuration (Configuration: [B]).
