From f9cd6be10ece07e10488c05e270a0b5860779864 Mon Sep 17 00:00:00 2001 From: Lennart Poettering Date: Mon, 3 Mar 2014 20:49:33 +0100 Subject: logind: ignore lid switch events for 30s after each suspend and 3min after startup This is needed to give USB docking stations and suchlike time to settle, so that a display connected to an USB docking station can actually act as a lid swith inhibitor correctly. With this change we should have somewhat reliable docking station support in place. --- src/login/logind-action.c | 15 ++++++++++++++- 1 file changed, 14 insertions(+), 1 deletion(-) (limited to 'src/login/logind-action.c') diff --git a/src/login/logind-action.c b/src/login/logind-action.c index c9d8bc5413..ae7b35055a 100644 --- a/src/login/logind-action.c +++ b/src/login/logind-action.c @@ -70,20 +70,33 @@ int manager_handle_action( return 0; } - /* If we are docked don't react to lid closing */ if (inhibit_key == INHIBIT_HANDLE_LID_SWITCH) { int n; + /* If we are docked don't react to lid closing */ if (manager_is_docked(m)) { log_debug("Ignoring lid switch request, system is docked."); return 0; } + /* If we have more than one or no displays connected, + * don't react to lid closing.
