Comment faire en sorte que Plymouth affiche les messages de démarrage lors du démarrage?

Je voudrais savoir comment créer un splash pour Ubuntu Maverick avec des messages de démarrage affichés lors du démarrage, ainsi qu’une barre de progression et un logo en rotation.

Ou, si possible, comment éditer un splash comportant déjà un logo en rotation et une barre de progression, et y ajouter des messages de démarrage.

C'est le thème que je voudrais éditer:

et je voudrais quelque chose comme ça:

enter image description here

ou ceci, qui est le splash exact que je veux créer:

enter image description here

j'ai pu trouver ce site web, il contient de nombreuses 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

Script de Plymouth

et ceci est un autre site Web qui peut aider avec les scripts

c'est 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);

D'accord, 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 trouvés utiles. Guide thématique de Plymouth Cet article comporte quatre parties que vous devez lire afin de comprendre l'essentiel de ce que nous faisons. (Je comparais leur script avec le script de mon splash pour comprendre ce que c'est, je recommande de le faire si quelqu'un doit suivre mes traces.) Script de Plymouth Ok ce lien a 2 pages ont dû passer par eux pour comprendre quoi faire. Il s'avère qu'ils étaient après la même chose que moi, qui consiste à diriger les messages de démarrage vers le splash de Plymouth où j'ai déjà un logo en rotation, un fond d'écran, une barre de progression.

Je devais donc éditer mon fichier /lib/lsb/init-functions et le faire pour qu'il envoie les messages d'erreur de démarrage/succès, etc. à Plymouth en ajoutant ce paragraphe

Jusqu'ici, je n'ai pas réussi à faire passer les messages à Plymouth, mais j'ai mieux compris le fonctionnement du script de Plymouth!

Je ne sais pas quoi d'autre est supposé faire pour que ça marche! en espérant que quelqu'un ici peut m'aider

D'accord, donc je travaille sur ce problème depuis 4 jours, et je l'ai presque complètement résolu. Jusqu'à présent, Plymouth a pu démarrer avec l'affichage des messages, mais malheureusement, les messages sont tronqués. En ce moment, j'essaie de modifier les scripts, mais je ne sais pas où se situe le problème dans le script/lib/lsb/init-functions ni dans /lib/plymouth/themes/"theme-name"/mdv.script.

Voici mon travail jusqu'à présent.

tout d'abord, vous devez faire en sorte que les fonctions init envoient des messages à Plymouth en lui donnant l'aspect suivant (parcourez chaque ligne pour voir les différences et copiez la ligne correspondant à l'envoi de Plymouth):

Fondamentalement, le script peut être appliqué à n'importe quel thème. Tout ce que vous avez à faire est de fournir les noms de fichier des images du dossier. Et changer quelques autres lignes pour ajuster les images à l'écran. Ou ce que vous faites, c’est que vous copiez la partie nécessaire, comme si vous vouliez la partie relative à la progression, il vous suffit de tout copier de

----------------------------------------- Barre de progression ------- -------------------------

jusqu'à

----------------------------------------- Mise à jour du statut ------- -------------------------

Une fois que vous avez fini d’éditer le fichier mdv.script, assurez-vous de bien utiliser Sudo update-initramfs -u et lors de votre prochain démarrage, vous verrez apparaître votre nouveau Splash.

Assurez-vous de vérifier les liens fournis dans ma question. Ils sont très instructifs et vous permettront de comprendre le script plymouth en un rien de temps.

Maintenant, si vous avez fait tout ce que j'ai dit ici, vous démarrez Splash devrait afficher des messages défilants. Maintenant, à propos de la partie tronquante, je suis en train de travailler dessus, mais c'est un peu ennuyeux de devoir redémarrer ma machine à chaque fois que je fais des changements. Est-il possible de tester un processus de démarrage alors que je suis connecté comme

Sudo plymouthd ; Sudo plymouth --show-splash ; Sudo plymouth update --status="Hello" ; sleep 2 ; Sudo plymouth update --status="This is a test. This is a test. This is a test. This is a test. This is a test. This is a test. " ; sleep 10 ; Sudo killall plymouthd

Vous pouvez également tester Plymouth en copiant la commande ci-dessus dans un fichier texte et en ajoutant Sudo plymouth update --status="your message" pour que davantage de messages défilent. Ensuite, rendez le fichier exécutable et exécutez-le dans un terminal.

J'espère que cela aidera tous ceux qui souhaitent modifier leur splash Plymouth. Bonne chance!!!

je sais que c'est un vieux fil, mais je pense connaître la réponse à propos de la troncature du texte ou non. Dans mon themename.script (pas le fichier themename.plymouth), j'utilise deux variables.

1. NUM_SCROLL_LINES
2. LINE_WIDTH

avec ces variables je peux définir combien de lignes seront affichées et combien de temps sont les lignes qui seront affichées. Le script a également une fonction qui tronque les lignes si elles sont trop longues à afficher.

J'espère que cela sera utile pour quelqu'un.

Mon problème dans opensuse 42.1 Leap est. plymouth n’affiche pas les messages de démarrage, comme ils sont écrits dans /var/log/boot.log. Il montre les appels système pour les services.

J'ai aussi édité/lib/lsb/init-functions de cette façon

if [ -x /usr/bin/plymouth ]; then
  /usr/bin/plymouth update --status="$@"
fi

ou ça

[ -x /usr/bin/plymouth ] && /usr/bin/plymouth update --status="$@"

Rien n'a fonctionné pour moi. Est-ce que quelqu'un a une idée?

Voici le nom de fichier.script que j'utilise

NUM_SCROLL_LINES=52;
LINE_WIDTH=120;

wallpaper_image = Image("background.png");
screen_width = Window.GetWidth();
screen_height = Window.GetHeight();
resized_wallpaper_image = wallpaper_image.Scale(screen_width,screen_height);
wallpaper_Sprite = Sprite(resized_wallpaper_image);
wallpaper_Sprite.SetZ(-100);

// Initialising text images and their positions
// 20 is the height (including line spacing) of each line
for (i=0; i < NUM_SCROLL_LINES; i++) {
  lines[i]= Image.Text("", 0, 0, 0);
  message_Sprite[i] = Sprite();
#  here you can set the hights and width of textdisplay. 0.005 uses almost the whole screen.
#  message_Sprite[i].SetPosition(screen_width * 0.2, (screen_height * 0.6) + (i * 20), 10000);
  message_Sprite[i].SetPosition(screen_width * 0.005, (screen_height * 0.005) + (i * 20), 10000);
}

// From ubuntu-logo
fun StringLength(string) {
  index = 0;
  str = String(string);
  while(str.CharAt(index)) index++;
    return index;
}

fun scroll_message_callback(text) {
  // Truncate the message if too long
  if (StringLength(text) > LINE_WIDTH) {
    text = text.SubString(0, LINE_WIDTH - 3);
    text += "...";
  }

  // Shift message one up
  for (i = 0; i < NUM_SCROLL_LINES - 1; i++) {
    lines[i] = lines[i+1];
  }

  // Create the image for the latest message
  # z.B. turquoise coloured text / (text, 0.28, 0.82, 0.80); // 1.0 = 100% 0.28 = 28% usw.
  lines[i] = Image.Text(text, 0.28, 0.82, 0.80);

  // Re-positioning the text images
  for (i = 0; i < NUM_SCROLL_LINES; i++) {
    message_Sprite[i].SetImage(lines[i]);
  }

}

Plymouth.SetUpdateStatusFunction(scroll_message_callback);
