Title:
  Update caused boot process hang

Status in nvidia-graphics-drivers package in Ubuntu:
  New
Status in ubuntu-release-upgrader package in Ubuntu:
  New

Bug description:
  After this last update I rebooted and the system hanged during boot
  without getting to the gnome login screen. I was at a black screen
  with the cursor flashing in the top left corner. I am able to get past
  this only by booting to recovery mode and dropping to root, then
  resuming the boot process. I must drop to root before resuming the
  boot or it will hang. It does not matter if I boot with kernel
  7.0.0-10 or 7.0.0-12 the behavior is the same.

  This latest version of 7.0.0-12 does seem to have fixed the problem
  with only seeing one of my three monitors, however (which is a bug I
  reported separately).
