Public bug reported: Since upgrading to 16.04LTS my HP 255 laptop no longer suspends when the lid is closed. The power management gui settings are correct, and suspend used to work perfectly in 14.04LTS.
Suspend is still available from the system menu, and works correctly when manually invoked from there or after a short power button press. The reason I suspect unity-settings-daemon is blocking the lid close action is that systemd-inhibit gives the following output.
