3b415d1d41
Adds a new plugin for setting the timeout before the display is turned off. The timeout value, in seconds, is controlled by the "display_idle_timeout" option. Setting the value to 0 disables the timeout and leaves the display always on. Change-Id: Ibc7dbad3b1ce6ec06ff0d50d937409914d18685a Implements: blueprint display-idle-timeout-plugin Co-Authored-By: Stefan Caraiman <scaraiman@cloudbasesolutions.com>
