From 7f73a6ed3ac3244d8d1ec3ab7a74b5a45a1350d9 Mon Sep 17 00:00:00 2001 From: rpm-build Date: Tue, 11 Sep 2018 10:19:44 -0400 Subject: [PATCH] monitor-manager: only reuse initial-config if monitor topology matches startup Right now we try to apply the current monitor config when a new monitor is attached. The current config obviously doesn't include the new monitor, so the new monitor isn't lit up. The only reason we apply the current config at all is to handle the startup case: We want to reuse the config set in Xorg when first logging in. This commit changes the code to look at the *initial config* instead of the current config, and only if the new monitor topology matches the start up topology. --- src/backends/meta-monitor-config-manager.c | 20 +++++++++++++++----- src/backends/meta-monitor-config-manager.h | 2 +- src/backends/meta-monitor-manager.c | 16 +++++++++++++++- 3 files changed, 31 insertions(+), 7 deletions(-) diff --git a/src/backends/meta-monitor-config-manager.c b/src/backends/meta-monitor-config-manager.c index 585ee7034..1ad342a44 100644 --- a/src/backends/meta-monitor-config-manager.c +++ b/src/backends/meta-monitor-config-manager.c @@ -40,6 +40,7 @@ struct _MetaMonitorConfigManager MetaMonitorConfigStore *config_store;
