Bug description:
  James Rice of Jump Networks noticed that there is a screen-blanker
  enabled on Ubuntu Server.

  James notes that this blanking is not enabling DPMS power saving
  (thereby negating any power-saving benefit), and is simply turning the
  screen content blank.   This means that the crash output is invisible
  which is unhelpful on a server (virtual or otherwise).

  Ideally the screen should (at a minimum) be turned on and unblanked at
  the point of an OOPs/crash being printed.
