Title:
Ubuntu server enables screenblanking, concealing crashdumps (DPMS is
not used)
Status in kbd package in Ubuntu:
Triaged
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.
