Title:
  Ubuntu 18.10 boots into black screen

Status in gdm3 package in Ubuntu:
  New

Bug description:
  I just upgraded from Ubuntu 18.04 to Ubuntu 18.10 on a Windows 10 dual
  boot machine.  The machine has a Nvidia GeForce GTX 1080 GPU.  I have
  tried to diagnose and fix the problem using prior posted solutions,
  such as video card issues with
  nomodeset(https://askubuntu.com/questions/162075/my-computer-boots-
  to-a-black-screen-what-options-do-i-have-to-fix-it and
  https://askubuntu.com/questions/1087559/cant-boot-ubuntu-properly-
  after-dual-boot-installation-with-windows-10) but this did not work,
  and the boot script no longer contains "quiet splash" anyways. Also in
  the boot script I set  acpi = off but then I get another error,
  perhaps for another thread (PKCS#7 signature not signed with a trusted
  key), and the boot instead crashes on this error.

  In recovery mode (4.18.0-10-generic) I tried running fsck but could
  not unmount the partition.  I am using 97% of my bootloader partition
  so I ran recovery mode's clean but that also did not fix the issue.

  I am not sure what else I should try - I anxiously await and
  appreciate any further guidance you may have.
