Je voudrais savoir comment créer un splash pour Ubuntu Maverick avec des messages de démarrage affichés lorsque je démarre, ainsi qu'une barre de progression et un logo tournant.
Ou, si possible, comment éditer un splash qui a déjà un logo tournant et une barre de progression, et y ajouter des messages de démarrage.
Voici le thème que je voudrais éditer:
et je voudrais quelque chose comme ça:
ou ceci, qui est le splash exact que je veux créer:
J'ai pu trouver ce site Web, il contient beaucoup d'informations utiles, mais j'ai du mal à en comprendre certaines. je n'ai jamais fait de script avant!
Créez votre propre écran de démarrage avec des messages de démarrage défilants
et ceci est un autre site Web qui peut aider avec les scripts
voici le script de la barre de progression dans le 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, j'ai donc fait beaucoup plus de recherches et j'ai pu en apprendre un peu plus sur Plymouth.
ce sont les sites que j'ai trouvé utiles. Guide thématique de Plymouth Il y a quatre parties à cet article que vous devez lire à travers pour comprendre l'essentiel de ce que nous faisons. (Je comparais leur script avec le script de mon splash pour comprendre ce qui est quoi, je recommande de le faire si quelqu'un veut suivre mes traces.) Script Plymouth Ok ce lien a 2 pages a dû les parcourir pour comprendre quoi faire . Il s'avère qu'ils recherchaient la même chose que moi, c'est-à-dire diriger les messages de démarrage vers le splash de Plymouth où j'ai déjà un logo tournant, un arrière-plan, une barre de progression.
J'ai donc dû éditer mon /lib/lsb/init-functionsfichier et le faire pour qu'il envoie les messages d'erreur / succès de démarrage, etc. à Plymouth en ajoutant ce paragraphe

Jusqu'à présent, je n'ai pas pu transmettre les messages à Plymouth, mais j'ai mieux compris comment fonctionne le script Plymouth!
Je ne sais pas quoi faire d'autre pour que ça marche! en espérant que quelqu'un ici puisse m'aider

OK, j'ai donc fourni presque toutes les informations nécessaires, si quelqu'un est familier avec cela, faites-moi savoir ce qui me manque pour faire passer les messages de démarrage à Plymouth. Merci
Si quelqu'un veut tester l'éclaboussure sans redémarrer, c'est une méthode simple 'Installez le paquet plymouth-x11 Exécutez sudo plymouthd; sudo plymouth --show-splash; dormir 10; sudo killall plymouthd ' askubuntu.com/questions/51078/…

Ohh et autre chose dois-je changer GRUB_CMDLINE_LINUX_DEFAULT = "silencieux splash" en GRUB_CMDLINE_LINUX_DEFAULT = "splash" pour que les messages soient affichés?

freedesktop.org/wiki/Software/Plymouth/Scripts une autre page de script plymouth. cela aide beaucoup si vous ne connaissez aucun javascript ou C.
