GDM3 fails to start, stalled at 'started bpfilter' on my HP laptop (model hp15-ay016nr) which runs Intel graphics, no nVidia hardware or drivers. So, this is not strictly an nVidia issue, which began after a Sat 8 December upgrade.
Booting previous kernels did not fix the problem. Disabling Wayland in /etc/gdm3/custom.conf also had no effect. I'm having a terrible time gathering system information because I can only log in to Gnome Shell as a Live Session User from the Ubuntu 18.10 Live Install USB drive -- or as root in Recovery Mode -- which results in limited access to user files and info on the installed system. Attempting to view many directories gets Access Denied You Don't Have Permissions. I even have trouble viewing my backup folders on my external USB drive, and I'm afraid I may lose access to them if I revert to 18.04 LTS, or install an alternate distro to replace the current Ubuntu 18.10. I'm not familiar with recent file system security "enhancements," but I think there have been changes with unanticipated consequences. I'm posting this as a temporary Live Session User off a Cosmic installation USB drive. None of my online account info is saved, and I have to search my pword/unname each time I visit any web site, it's a huge pain. I have been hampered in researching this, but I have seen the same symptoms reported by Arch Linux users as well. BTW, Cripton's tip above to enable networking did allow me to run 'apt update' in recovery mode to confirm no pending upgrades (so, no fixes pending.) But, unfortunately Resuming a normal boot did not result in gdm3 successfully starting for me. -- 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".
