5.16 Power button defaults to ACPI Suspend

By default, Oracle Linux 7 Update 7 in graphical (GUI) console mode treats the hardware power button as equivalent to the ACPI "Sleep" button, which puts the system into low-power sleep mode. This behavior is specific to GNOME desktop environment.

In previous Oracle Linux versions, the hardware power button initiated a system shutdown. To make Oracle Linux 7 do the same, create a file named /etc/dconf/db/local.d/01-shutdown-button with the following content:

[org/gnome/settings-daemon/plugins/power]
button-power='shutdown'

Then run the following command:

# dconf update

You must log out of the desktop environment and log back in for the new setting to take effect. (Bug ID 25597898)
