See also ubuntu-postinstall.
Slim down the system¶
Manually add required packages first.
sudo apt install ubuntu-desktop-minimal apturl apturl-common avahi-utils branding-ubuntu dgxstation-desktop dgxstation-grub gnome-tweaks language-pack-en language-pack-gnome-en yaru-theme-unity gedit nautilus-share nvidia-plymouth nvidia-update-manager samba tdb-tools ibus-chewing
Then remove unneeded packages, for example:
The apt packages manager will not accidentally remove packages you need due to nvidia-system-station dependency.
