Overview
This page demonstrates how one can shut the lid of a laptop computer running NST or Fedora without suspending the system. This is especially useful when NST is booted in console mode. The systemd-logind.service can be configured to "ignore" the suspension system power action. This systemd service handles various hardware state system power functionality.
Edit Configuration File for systemd-logind.service
The systemd-logind.service has a configuration file: "/etc/systemd/logind.conf" that contains an entry for controlling the system power when the lid switch is in the Closed position. If one wants to allow an NST system running on a laptop computer not to enter the Suspension power state, then the HandleLidSwitch entry needs to be set to: "ignore".
The HandleLidSwitch entry is set to: "ignore" in the listing below for file: "/etc/systemd/logind.conf"
[root@shopper2 ~]# cat /etc/systemd/logind.conf # This file is part of systemd. # # systemd is free software; you can redistribute it and/or modify it # under the terms of the GNU Lesser General Public License as published by # the Free Software Foundation; either version 2.1 of the License, or # (at your option) any later version. # # Entries in this file show the compile time defaults. # You can change settings by editing this file. # Defaults can be restored by simply deleting this file. # # See logind.conf(5) for details.
