[virt-tools-list] [PATCH virt-viewer] Avoid warning when loading initial monitor mapping
When started in fullscreen mode with a monitor-mapping configuration option, we are getting the following warnings on the terminal: (process:27428): Gdk-CRITICAL **: gdk_screen_get_n_monitors: assertion 'GDK_IS_SCREEN (screen)' failed ** (process:27428): WARNING **: Invalid monitor-mapping configuration: monitor #1 for display #1 does not exist This is apparently because we were processing the fallback monitor mapping before the graphic server display was opened, so gdk_screen_get_default() returned NULL. This resulted in gdk_screen_get_n_monitors() reporting that we had 0 monitors. This patch moves the fallback monitor mapping parsing from virt_viewer_app_init() to virt_viewer_app_on_application_startup(), after chaining up to the base class startup() vfunc. The graphic server display is opened in the base class vfunc, so by the time that returns, we should be able to query the number of monitors. The patch also adds a check in virt_viewer_parse_monitor_mappings() to ensure that we pass a sane value for nmonitors. --- src/virt-viewer-app.c | 2 +- src/virt-viewer-util.c | 7 +-- 2 files changed, 6 insertions(+), 3 deletions(-) diff --git a/src/virt-viewer-app.c b/src/virt-viewer-app.c index 2e7e193..8c5c3f5 100644 --- a/src/virt-viewer-app.c +++ b/src/virt-viewer-app.c @@ -1730,7 +1730,6 @@ virt_viewer_app_init(VirtViewerApp *self) g_clear_error(); -self->priv->initial_display_map = virt_viewer_app_get_monitor_mapping_for_section(self, "fallback"); g_signal_connect(self, "notify::guest-name", G_CALLBACK(title_maybe_changed), NULL); g_signal_connect(self, "notify::title", G_CALLBACK(title_maybe_changed), NULL); g_signal_connect(self, "notify::guri", G_CALLBACK(title_maybe_changed), NULL); @@ -1807,6 +1806,7 @@ virt_viewer_app_on_application_startup(GApplication *app) self->priv->main_window = virt_viewer_app_window_new(self, virt_viewer_app_get_first_monitor(self)); self->priv->main_notebook = GTK_WIDGET(virt_viewer_window_get_notebook(self->priv->main_window)); +self->priv->initial_display_map = virt_viewer_app_get_monitor_mapping_for_section(self, "fallback"); virt_viewer_app_set_kiosk(self, opt_kiosk); virt_viewer_app_set_hotkeys(self, opt_hotkeys); diff --git a/src/virt-viewer-util.c b/src/virt-viewer-util.c index 0491f73..6b63133 100644 --- a/src/virt-viewer-util.c +++ b/src/virt-viewer-util.c @@ -641,11 +641,14 @@ virt_viewer_shift_monitors_to_origin(GHashTable *displays) GHashTable* virt_viewer_parse_monitor_mappings(gchar **mappings, const gsize nmappings, const gint nmonitors) { -GHashTable *displaymap = g_hash_table_new(g_direct_hash, g_direct_equal); -GHashTable *monitormap = g_hash_table_new(g_direct_hash, g_direct_equal); +GHashTable *displaymap; +GHashTable *monitormap; gint i, max_display_id = 0; gchar **tokens = NULL; +g_return_val_if_fail(nmonitors != 0, NULL); +displaymap = g_hash_table_new(g_direct_hash, g_direct_equal); +monitormap = g_hash_table_new(g_direct_hash, g_direct_equal); if (nmappings == 0) { g_warning("Empty monitor-mapping configuration"); goto configerror; -- 2.9.3 ___ virt-tools-list mailing list virt-tools-list@redhat.com https://www.redhat.com/mailman/listinfo/virt-tools-list
