Dear Daniel! Thank you for replying and for analysis.
1. On clean installation on physical hardware the behavior of Power Button is as follows: * on console ttys system shutdowns * on the GDM system goes to sleep (suspends) * in GNOME session it asks what to do if run `gsettings set org.gnome.settings-daemon.plugins.power power-button-action interactive` manually (no GUI option - it is a bug 1769614 ) So seems to be expected behavior. 2. But if I run Ubuntu as VirtualBox 5.1 guest (this bug report): * all settings are ignored (both `logind.conf` and `gsettings`). * I do not have "When the Power Button is pressed" in `gnome-control-center power` How to debug this? Should I report special bug to upstream? --- You can see images on my AskUbuntu question ( https://askubuntu.com/q/1032461/66509 ). -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to gnome-settings-daemon in Ubuntu. https://bugs.launchpad.net/bugs/1769372 Title: Prompt the user when the power button is pressed on VirtualBox guest Status in gnome-control-center package in Ubuntu: In Progress Status in gnome-settings-daemon package in Ubuntu: Triaged Bug description: Steps to reproduce: 1.
