I'm running Ubuntu 16.10 Desktop on a Lenovo Ideapad Z510, with the Gnome 3.22 desktop environment.

While I can manage to get the power button to suspend by setting org.gnome.settings-daemon.plugins.power, power-button-action = suspend, setting the power-button-action to hibernate does not work.

In investigating the issue, it seems that there are three possible systems that may be responsible for the issue here (in no particular order):

  • ACPI
  • Systemd
  • Gnome

I can confirm that the lid switch of my system is handled through systemd (setting HandleLidSwitch in logind.conf), but editing HandlePowerKey does not appear to do anything.

Can someone please suggest how to set the power button to hibernate on button press? Or how best to troubleshoot this issue?

Thanks much

Rich

After a bit of sleuthing, I found some additional details about how systemd's logind works here (more specifically, how logind uses policies through polkit), which ultimately led me to the solution to my issue here. What fun!
