From 702f204a281c6525da6bfcd2286d70b1ab6eab13 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Jonas=20=C3=85dahl?= Date: Fri, 3 Nov 2017 15:58:02 +0800 Subject: [PATCH 1/4] monitor-config-manager: Don't include closed laptop panel in config key When deriving the list of disabled monitors when creating new monitors configs, don't include the laptop panel if the lid is currently closed, as we consider the laptop panel nonexistent when the laptop lid is closed when it comes to configuration. The laptop panel connector(s) will either way be appropriately disabled anyway, as the field listing disabled monitors in the configuration do not affect actual CRTC/connector assignments. https://bugzilla.gnome.org/show_bug.cgi?id=788915 --- src/backends/meta-monitor-config-manager.c | 4 ++++ 1 file changed, 4 insertions(+) diff --git a/src/backends/meta-monitor-config-manager.c b/src/backends/meta-monitor-config-manager.c index 2fe620767..2a7287778 100644 --- a/src/backends/meta-monitor-config-manager.c +++ b/src/backends/meta-monitor-config-manager.c @@ -1308,6 +1308,10 @@ meta_monitors_config_new (MetaMonitorManager *monitor_manager, MetaMonitor *monitor = l->data; MetaMonitorSpec *monitor_spec; + if (meta_monitor_manager_is_lid_closed (monitor_manager) && + meta_monitor_is_laptop_panel (monitor)) + continue; + monitor_spec = meta_monitor_get_spec (monitor); if (meta_logical_monitor_configs_have_monitor (logical_monitor_configs, monitor_spec)) -- 2.14.2 From 584e2b93d9f28557cfe8a6ff720b4c3e45c458ab Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Jonas=20=C3=85dahl?= Date: Fri, 3 Nov 2017 16:03:23 +0800 Subject: [PATCH 2/4] monitor-manager: Compare keys when checking whether a config is complete We only counted configured monitors and whether the config was applicable (could be assigned), howeverwe didn't include disabled monitors when comparing. This could caused incorrect configurations to be applied when trying to use the previous configuration. One scenario where this happened was one a system with one laptop screen and one external monitor that was hot plugged some point after start up. When the laptop lid was closed, the 'previous configuration' being the configuration where only the laptop panel was enabled, passed 'is-complete' check as the number of configured monitors were correct, and the configuration was applicable. Avoid this issue by simply comparing the configuration key of the previous configuration and the configuration key of the current state. This correctly identifies a laptop panel with the lid closed as inaccessible, thus doesn't incorrectly revert to the previous configuration. https://bugzilla.gnome.org/show_bug.cgi?id=788915 --- src/backends/meta-monitor-config-manager.c | 7 +++--- src/backends/meta-monitor-config-manager.h | 2 ++ src/backends/meta-monitor-manager.c | 36 +++++++++--------------------- 3 files changed, 16 insertions(+), 29 deletions(-) diff --git a/src/backends/meta-monitor-config-manager.c b/src/backends/meta-monitor-config-manager.c index 2a7287778..bdf863055 100644 --- a/src/backends/meta-monitor-config-manager.c +++ b/src/backends/meta-monitor-config-manager.c @@ -326,8 +326,8 @@ meta_monitor_config_manager_assign (MetaMonitorManager *manager, return TRUE; } -static MetaMonitorsConfigKey * -create_key_for_current_state (MetaMonitorManager *monitor_manager) +MetaMonitorsConfigKey * +meta_create_monitors_config_key_for_current_state (MetaMonitorManager *monitor_manager) { MetaMonitorsConfigKey *config_key; GList *l; @@ -369,7 +369,8 @@ meta_monitor_config_manager_get_stored (MetaMonitorConfigManager *config_manager MetaMonitorsConfig *config; GError *error = NULL; - config_key = create_key_for_current_state (monitor_manager); + config_key = + meta_create_monitors_config_key_for_current_state (monitor_manager); if (!config_key) return NULL; diff --git a/src/backends/meta-monitor-config-manager.h b/src/backends/meta-monitor-config-manager.h index 516909dd7..c36df38e6 100644 --- a/src/backends/meta-monitor-config-manager.h +++ b/src/backends/meta-monitor-config-manager.h @@ -136,6 +136,8 @@ void meta_logical_monitor_config_free (MetaLogicalMonitorConfig *logical_monitor void meta_monitor_config_free (MetaMonitorConfig *monitor_config); +MetaMonitorsConfigKey * meta_create_monitors_config_key_for_current_state (MetaMonitorManager *monitor_manager); + gboolean meta_logical_monitor_configs_have_monitor (GList *logical_monitor_configs, MetaMonitorSpec *monitor_spec); diff --git a/src/backends/meta-monitor-manager.c b/src/backends/meta-monitor-manager.c index 8b548fd68..eb3612cf0 100644 --- a/src/backends/meta-monitor-manager.c +++ b/src/backends/meta-monitor-manager.c @@ -1551,35 +1551,19 @@ static gboolean meta_monitor_manager_is_config_complete (MetaMonitorManager *manager, MetaMonitorsConfig *config) { - GList *l; - unsigned int configured_monitor_count = 0; - unsigned int expected_monitor_count = 0; - - for (l = config->logical_monitor_configs; l; l = l->next) - { - MetaLogicalMonitorConfig *logical_monitor_config = l->data; - GList *k; + MetaMonitorsConfigKey *current_state_key; + gboolean is_config_complete; - for (k = logical_monitor_config->monitor_configs; k; k = k->next) - configured_monitor_count++; - } - - for (l = manager->monitors; l; l = l->next) - { - MetaMonitor *monitor = l->data; + current_state_key = + meta_create_monitors_config_key_for_current_state (manager); + if (!current_state_key) + return FALSE; - if (meta_monitor_is_laptop_panel (monitor)) - { - if (!meta_monitor_manager_is_lid_closed (manager)) - expected_monitor_count++; - } - else - { - expected_monitor_count++; - } - } + is_config_complete = meta_monitors_config_key_equal (current_state_key, + config->key); + meta_monitors_config_key_free (current_state_key); - if (configured_monitor_count != expected_monitor_count) + if (!is_config_complete) return FALSE; return meta_monitor_manager_is_config_applicable (manager, config, NULL); -- 2.14.2
