Norbert, the upstream bug is https://gitlab.gnome.org/GNOME/gnome- settings-daemon/issues/46
Once that issue is fixed in GNOME, it can be fixed in the current development release of Ubuntu and then in Ubuntu 18.04 LTS. Comment #18 here was about something different so you can probably ignore that. -- 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 a VM Status in gnome-control-center package in Ubuntu: Invalid Status in gnome-settings-daemon package in Ubuntu: Triaged Bug description: Steps to reproduce: 1.
