Please, can someone tell me: Why was /etc/kbd/config (and also
/etc/kbd/remap) removed on kbd package Version 2.0.4-2ubuntu1 in bionic?
If it had been left, the console could still blank and powerdown (DPMS)!

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.
