When no user is logged in (the initial user selection screen is displayed) the idle system goes into suspend (sleep) mode. The timeout for this event is 20 minutes. 2. I tried to cancel the entering into sleep mode. To do this, I altered the sleep-inactive-ac-timeout and sleep-inactive-battery- timeout parameters to 0. The command sudo -H -u lightdm dbus-launch --exit-with-session gsettings list-recursively org.gnome.settings-daemon.plugins.power gives the output: root@supercat:/home/supercat# sudo -H -u lightdm dbus-launch --exit-with-session gsettings list-recursively org.gnome.settings-daemon.plugins.power No protocol specified org.gnome.settings-daemon.plugins.power lid-close-ac-action 'suspend' org.gnome.settings-daemon.plugins.power time-critical 300 org.gnome.settings-daemon.plugins.power power-button-action 'suspend' org.gnome.settings-daemon.plugins.power lid-close-suspend-with-external-monitor false org.gnome.settings-daemon.plugins.power button-hibernate 'hibernate' org.gnome.settings-daemon.plugins.power idle-dim true org.gnome.settings-daemon.plugins.power button-power 'suspend' org.gnome.settings-daemon.plugins.power lid-close-battery-action 'suspend' org.gnome.settings-daemon.plugins.power priority 0 org.gnome.settings-daemon.plugins.power idle-brightness 30 org.gnome.settings-daemon.plugins.power active true org.gnome.settings-daemon.plugins.power critical-battery-action 'hibernate' org.gnome.settings-daemon.plugins.power button-suspend 'suspend' org.gnome.settings-daemon.plugins.power button-sleep 'hibernate' org.gnome.settings-daemon.plugins.power percentage-critical 3 org.gnome.settings-daemon.plugins.power sleep-inactive-ac-timeout 0 org.gnome.settings-daemon.plugins.power sleep-inactive-ac-type 'suspend' org.gnome.settings-daemon.plugins.power ambient-enabled true org.gnome.settings-daemon.plugins.power notify-perhaps-recall true org.gnome.settings-daemon.plugins.power percentage-low 10 org.gnome.settings-daemon.plugins.power percentage-action 2 org.gnome.settings-daemon.plugins.power sleep-inactive-battery-type 'suspend' org.gnome.settings-daemon.plugins.power time-low 1200 org.gnome.settings-daemon.plugins.power sleep-inactive-battery-timeout 0 org.gnome.settings-daemon.plugins.power time-action 120 org.gnome.settings-daemon.plugins.power use-time-for-policy true 3. I checked the result, the system still suspends (goes into sleep mode) in 20 minutes. I checked the IdleAction parameter in /etc/systemd/logind.conf, because it may affect the suspend mode. It is set to ignore. # 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.
