Actually, my apologies, I am not (and I can't figure out how to edit my last comment, if it is possible) ...
I was in 18.04 Workstation with GUI disabled when I was adding consoleblank to GRUB_CMDLINE_LINUX_DEFAULT - that wasn't working at all in Server though, so I tried adding it to GRUB_CMDLINE_LINUX and I am AMAZED to see that the display is actually OFF for the first time in 3-4 weeks I've been fighting with all this. No issues here, please disregard my previous comment! -- 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. Currently the display stays on 24x7 with idle keyboard input. 1) My release information is as follows: Description: Ubuntu 18.04 LTS Release: 18.04 2) I am not sure what package this issue is tied to. The current kernel appears to have DPMS support enabled, per the configuration file in /boot. If the kernel is responsible, below is the version I am running. linux-generic: Installed: 4.15.0.20.23 3) I expected to have DPMS support for my console as in the previous release of Ubuntu Server. 4) What happened instead is my monitor stays on all the time, without DPMS controlling it. --- AlsaVersion: Advanced Linux Sound Architecture Driver Version k4.15.0-20-generic.
