[Kernel-packages] [Bug 869017] Re: Ubuntu server enables screenblanking, concealing crashdumps (DPMS is not used)
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 Kernel Packages, which is subscribed to linux 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.

[Kernel-packages] [Bug 1767568] Re: Console DPMS Nonfunctional in Ubuntu Server 18.04
Ubuntu 16.04.6 LTS + HWE doesn't seem to do the DPMS I'm testing it again, because I have to wait a lot between tests to be 100% sure. I don't know the exact time for it to trigger, so I don't sit there waiting. I just reboot, go do something else, and check back after a while. I won't report back on this configuration unless the results are different. Next test should be 16.10. So far the issue seems kernel related? Maybe default build options? And /etc/kbd/config seems to be for something else. The time configured there was 30 mins, I changed it to 1 minute and didn't get the results I expected. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1767568 Title: Console DPMS Nonfunctional in Ubuntu Server 18.04 Status in linux package in Ubuntu: Confirmed Bug description: My console display is DPMS capable, i.e., power management functions worked before upgrading from Ubuntu Server 16.0.4.4.

my First test: Ubuntu 16.04.6 LTS, with all the updates no HWE, might try that later. So far it works fine. Some time after boot the monitor went to standby. At one point, after using the arrow key to wake it up. It blanked but didn't go into standby, so the monitor was on but full black. I wonder if it was because the login prompt had some input? I could wake it up and login normally. Then I logged out and waited, and it went to standby like it was supposed to. I quite haven't figured out what happened then I have noticed that the /etc/kbd/config is present on 16.04, I believe it was missing on 18.04.

[Kernel-packages] [Bug 1767568] Re: Console DPMS Nonfunctional in Ubuntu Server 18.04
The problem seems present in 19.04. My monitor stays ON, exactly as described in this bug. And not much work seems to have been done on this bug? Is the rc.local fix good enough for blanking, or actual monitor stand by? Moe importantly, could we find exactly on what file or package 16.04 differs from 18.04 so we can revert, or improve the change properly. I guess we might need to fine grain those change increments, to find which is the first Ubuntu version where this took place. 16.04 vs 16.10 vs 17.04 vs 17.10 vs 18.04 Does installing with live-server vs alternate have any effect on this? Some of these questions are answered easily, and I guess I can start trying clean installs of various Ubuntu servers. too see which is the first to break.
