So this "fix" seems to cause Kernels released with zesty (and newer) keep the monitor always ON. No blanking, and no power down either.
Before this fix, a clean install of Ubuntu server would signal the monitor to sleep/standby after a short while. Now the default behavior is to leave the monitor always on, wasting power. While blanking itself should be negligible to power savings and monitor longevity, sleep states are still an important feature. https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1767568 -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to kbd in Ubuntu. https://bugs.launchpad.net/bugs/869017 Title: Ubuntu server enables screenblanking, concealing crashdumps (DPMS is not used) Status in kbd package in Ubuntu: Invalid Status in linux package in Ubuntu: Fix Released Status in kbd source package in Zesty: Invalid Status in linux source package in Zesty: Fix Released Status in kbd package in Debian: Fix Released 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.
