Ich möchte wissen, wie ich einen Splash für Ubuntu Maverick mit Startmeldungen, die beim Booten angezeigt werden, sowie einem Fortschrittsbalken und einem sich drehenden Logo erstellen kann.
Oder, wenn möglich, wie Sie einen Splash bearbeiten, der bereits ein sich drehendes Logo und einen Fortschrittsbalken enthält, und ihm Startmeldungen hinzufügen.
Dies ist das Thema, das ich bearbeiten möchte:
und ich möchte so etwas:
oder das, was genau der Splash ist, den ich erstellen möchte:
Ich konnte diese Website finden, sie enthält viele nützliche Informationen, aber es fällt mir schwer, einige davon zu verstehen. Ich habe noch nie ein Skript geschrieben!
Erstellen Sie Ihren eigenen Begrüßungsbildschirm mit scrollenden Startmeldungen
und dies ist eine andere Website, die bei der Skripterstellung helfen kann
Dies ist das Skript für den Fortschrittsbalken im Splash:
#----------------------------------------- Progress Bar --------------------------------
progress_box.image = Image("progress_box.png");
progress_box.sprite = Sprite(progress_box.image);
progress_box.x = Window.GetX() + Window.GetWidth() / 2 - progress_box.image.GetWidth() / 2;
progress_box.y = Window.GetY() + Window.GetHeight() * 0.65 - progress_box.image.GetHeight() / 2;
progress_box.sprite.SetPosition(progress_box.x, progress_box.y, 0);
progress_bar.original_image = Image("progress_bar.png");
progress_bar.sprite = Sprite();
progress_bar.x = Window.GetX() + Window.GetWidth() / 2 - progress_bar.original_image.GetWidth() / 2;
progress_bar.y = Window.GetY() + Window.GetHeight() * 0.65 - progress_box.image.GetHeight() / 2 + (progress_box.image.GetHeight() - progress_bar.original_image.GetHeight()) / 2;
progress_bar.sprite.SetPosition(progress_bar.x, progress_bar.y, 1);
fun progress_callback (duration, progress)
{
if (progress_bar.image.GetWidth () != Math.Int (progress_bar.original_image.GetWidth () * progress))
{
# add the * 3 to multiply the speed of the progress bar by 3
progress_bar.image = progress_bar.original_image.Scale(progress_bar.original_image.GetWidth(progress_bar.original_image) * progress * 3, progress_bar.original_image.GetHeight());
progress_bar.sprite.SetImage (progress_bar.image);
}
}
Plymouth.SetBootProgressFunction(progress_callback);
OK, also habe ich viel mehr gesucht und konnte ein bisschen mehr über Plymouth lernen.
Dies sind die Websites, die ich nützlich fand. Plymouth Theming Guide Der Artikel besteht aus vier Teilen, die Sie lesen müssen, um einen Überblick über unsere Aktivitäten zu erhalten. (Ich habe ihr Skript mit dem Skript verglichen, damit mein Splash versteht, was was ist. Ich empfehle, dies zu tun, wenn jemand in meine Fußstapfen treten soll.) Plymouth-Skripterstellung Ok, dieser Link hat 2 Seiten durchlaufen müssen, um zu verstehen, was zu tun ist . Es stellte sich heraus, dass sie dem gleichen Ziel entsprachen, nämlich Startmeldungen an den Plymouth-Splash weiterzuleiten, in dem sich bereits ein rotierendes Logo, ein Hintergrund und eine Fortschrittsanzeige befinden.
Also musste ich meine /lib/lsb/init-functionsDatei bearbeiten und sie so gestalten, dass sie den Startfehler / Erfolgsmeldungen usw. an Plymouth sendet, indem ich diesen Absatz hinzufüge
# SEND MESSAGES TO PLYMOUTH

Bisher konnte ich die Nachrichten nicht an Plymouth weiterleiten, aber ich verstand besser, wie Plymouth-Skripte funktionieren!
Ich weiß nicht, was ich sonst noch tun soll, damit es funktioniert! Ich hoffe, hier kann mir jemand helfen

OK, ich habe fast alle erforderlichen Informationen bereitgestellt. Wenn jemand damit vertraut ist, kann er mir mitteilen, was mir fehlt, um die Startmeldungen an Plymouth weiterzuleiten. Vielen Dank
Wenn jemand den Splash testen möchte, ohne ihn neu zu starten, ist dies eine einfache Methode. Installieren Sie das Paket plymouth-x11. Führen Sie sudo plymouthd aus. sudo plymouth - show-splash; schlaf 10; sudo killall plymouthd

Ohh und noch etwas sollte ich GRUB_CMDLINE_LINUX_DEFAULT = "quiet splash" in GRUB_CMDLINE_LINUX_DEFAULT = "splash" ändern, damit die Nachrichten angezeigt werden?

freedesktop.org/wiki/Software/Plymouth/Scripts Eine weitere Plymouth-Skriptseite. Es hilft sehr, wenn Sie kein Javascript oder C kennen.
