I forgot to include introductory links to this complicated issue. My crude understanding is that systemd handles system initialization, calling bpfilter (replacing iptables) which is handled by the linux kernel.

I'm still trying to figure out how to remove the amateurish Debian swirl background. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to mutter in Ubuntu. https://bugs.launchpad.net/bugs/1798790 Title: Ubuntu 18.10 login screen never appears when using the Nvidia driver Status in gdm3 package in Ubuntu: Confirmed Status in mutter package in Ubuntu: Confirmed Bug description: https://gitlab.gnome.org/GNOME/gdm/issues/435 --- The boot process hangs with the last message being "started bpfilter". There is unusual Network activity during that time. The light of the WiFi adapter is blinking a lot. I am not sure the problem is with the gdm3 package. As a matter of fact, I would remove it and let someone more experienced to set it. I'm afraid I might break something, though. The specific steps or actions you took that caused you to encounter the problem: 1. Boot Ubuntu 18.10 with the Nvidia proprietary drivers installed. The behavior you expected: I expected Ubuntu 18.10 to boot normally. The behavior you actually encountered: The computer gets stuck in a command-like environment with the last message being "started bpfilter". You can't type any commands. I have found that uninstalling the Nvidia proprietary drivers by going into recovery mode fixes the issue. Booting with the earlier kernel doesn't fix the issue. Installing the earlier v.340 driver also doesn't fix the issue. This (https://askubuntu.com/questions/1032639/ubuntu-18-04-stuck-in- boot-after-starting-gnome-display-manager-on-intel-graphic) seems relevant. This is where I found the "solution".
