I found a workaround in my case: https://askubuntu.com/questions/1167445/monitors-do-not-enter-powersave-sleep-mode-after-screen-blanking/
Changing the input setting from *auto* to *hdmi* on my AOC monitor fixed the problem. It seems monitors can *poll* the graphic card (CEC?): that way the computer somehow responds by waking up all monitors. I consider this stil a bug. Not sure if this is a gnome-screensaver bug, but it is a nasty one (wasting energy). IMHO Ubuntu should be able to turn of monitors (powersdave mode) with default factory setting. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1292041 Title: Lockscreen doesn't turn off the screen To manage notifications about this bug go to: https://bugs.launchpad.net/oem-priority/+bug/1292041/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
