Title:
  current boot config dims screen during initramfs

Status in initramfs-tools package in Ubuntu:
  Expired
Status in linux package in Ubuntu:
  Expired

Bug description:
  This is a weird one. Shortly after moving to 17.10, my laptop has
  started dimming its internal screen to minimum brightness at the start
  of initramfs execution. shortly thereafter it restores it to normal
  brightness, but that only happens *after* typing in encrypted
  filesystem passwords, so the password dialogues are practically
  invisible. Not sure why its doing this, but whatever's restoring the
  brightness should do it before prompting for filesystem mounting so
  these prompts are actually visible.
