From: Simon Fowler Date: Fri, 9 Feb 2018 16:37:39 +0000 (+1000) Subject: Suspend on lid close based on power status. (#8016) X-Git-Tag: v238~119 X-Git-Url: http://git.ipfire.org/gitweb.cgi?a=commitdiff_plain;h=e25937a3ed740ed0618a8943dee32e8966541cdf;p=thirdparty%2Fsystemd.git Suspend on lid close based on power status. (#8016) This change adds support for controlling the suspend-on-lid-close behaviour based on the power status as well as whether the machine is docked or has an external monitor. For backwards compatibility the new configuration file variable is ignored completely by default, and must be set explicitly before being considered in any decisions. --- diff --git a/man/logind.conf.xml b/man/logind.conf.xml index 8d2bfc5d5bf..4a64ddb8277 100644 --- a/man/logind.conf.xml +++ b/man/logind.conf.xml @@ -211,6 +211,7 @@ HandleSuspendKey= HandleHibernateKey= HandleLidSwitch= + HandleLidSwitchExternalPower= HandleLidSwitchDocked= Controls how logind shall handle the @@ -235,12 +236,17 @@ HandleSuspendKey= and HandleLidSwitch= default to suspend. - HandleLidSwitchDocked= defaults to - ignore. + HandleLidSwitchExternalPower= is completely + ignored by default (for backwards compatibility) — an explicit + value must be set before it will be used to determine + behaviour.
