_ hibernation できない…

sudo pacman -Syu したら hibernation できなくなった。

このへんかなぁ。

_ gdk_display_close 不安定すぎ…

Enter キーで閉じるのは問題ない。

focus して Enter キーで閉じると warning / critical が1つずつ。

click して閉じるても warning / critical が1つずつ。

このプログラムを改造して、clicked の callback 内で gdk_display_close() するようにすると、 必ず abort する。

static void clicked(GtkWidget *w, gpointer user_data)
{
    GtkWidget *top = user_data;
    GdkDisplay *dpy = gtk_widget_get_display(top);
    gtk_widget_destroy(top);

    gtk_main_quit();

    gdk_display_close (dpy);
}

{
    gtk_init(&argc, &argv);

    gtk_container_add(GTK_CONTAINER(top), btn);

ん？ signal handler の中で自分を destroy しちゃいけなかったっけ？ そんなルールあったかな…
