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.
