Actually there's a simpler solution. Please try this:
Download the latest "daily" version of 18.04 and install that from scratch (wiping the previous install): http://cdimages.ubuntu.com/bionic/daily-live/current/bionic-desktop-amd64.iso
You should then be completely free of bug 1727356 without needing to even update. But if the problem does still happen after that then please:
1. Reproduce the problem of the login screen not appearing (without using recovery mode).
2. Reboot and start in recovery mode.
3. Run: journalctl -b-1 > prev_boot.txt and send us the resulting file 'prev_boot.txt'.
