¿Cómo hacer que Plymouth muestre mensajes de arranque al arrancar?

20

Me gustaría saber cómo crear un splash para Ubuntu Maverick con mensajes de arranque que se muestran cuando inicio, así como una barra de progreso y un logotipo giratorio.

O, si es posible, cómo editar un splash que ya tiene un logotipo giratorio y una barra de progreso, y agregarle mensajes de arranque.

Este es el tema que me gustaría editar:

y me gustaría algo como esto:

o esto, que es el chapoteo exacto que quiero crear:

Pude encontrar este sitio web que tiene mucha información útil, pero me cuesta entenderlo. no he hecho ninguna secuencia de comandos antes!

Cree su propia pantalla de bienvenida con mensajes de inicio de desplazamiento

Plymouth Scripting

y este es otro sitio web que puede ayudar con las secuencias de comandos

Este es el script para la barra de progreso en el 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);

Bien, busqué mucho más y pude aprender un poco más sobre Plymouth.

Estos son los sitios que encontré útiles. Guía de temas de Plymouth Hay cuatro partes de ese artículo que debe leer a través de ellas para obtener una idea general de lo que estamos haciendo. (Estaba comparando su secuencia de comandos con la secuencia de comandos para entender qué es qué, recomiendo hacerlo si alguien debe seguir mis pasos.) Escritura de Plymouth Ok, este enlace tiene 2 páginas que tuvieron que recorrer para entender qué hacer . Resulta que buscaban lo mismo que yo, que es dirigir los mensajes de arranque al inicio de Plymouth donde ya tengo un logotipo giratorio, fondo y barra de progreso.

Así que tuve que editar mi /lib/lsb/init-functionsarchivo y hacerlo para que enviara los mensajes de error / éxito de arranque, etc. a Plymouth agregando este párrafo

Hasta el momento no pude transmitir los mensajes a Plymouth, ¡pero entendí mejor cómo funcionan los scripts de Plymouth!

¡No sé qué más se supone que debo hacer para que funcione! esperando que alguien aquí pueda ayudarme

OK, así que he proporcionado casi toda la información necesaria, si alguien está familiarizado con esto, hágame saber lo que me falta para enviar los mensajes de arranque a Plymouth. Gracias

Ah, y otra cosa, ¿debería cambiar GRUB_CMDLINE_LINUX_DEFAULT = "splash tranquilo" a GRUB_CMDLINE_LINUX_DEFAULT = "splash" para que se muestren los mensajes?

Bien, he estado trabajando en este problema durante 4 días seguidos, y casi lo soluciono por completo. Hasta ahora pude hacer que Plymouth se iniciara con los mensajes mostrados, pero desafortunadamente los mensajes están truncados. En este momento estoy tratando de modificar los scripts, pero no sé dónde está el problema en el script / lib / lsb / init-functions o /lib/plymouth/themes/"theme-name"/mdv.script.

Aquí está mi trabajo hasta ahora.

primero tiene que hacer que las funciones init envíen mensajes a Plymouth haciéndolo así (revise cada línea para ver las diferencias y copie la línea que corresponde al envío de Plymouth):

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

       text = pretext + text;

       if (nobreak == 1) pretext = text;
       else pretext = ">";

   }


#Create the image for the latest message

     lines[i] = Image.Text(text, msg_color[0], msg_color[1], msg_color[2]);

#Re-positioning the text images

  for (i = 0; i < NUM_SCROLL_LINES; i++) {
     message_sprite[i].SetImage(lines[i]);
   }
}

 Plymouth.SetUpdateStatusFunction(update_status_callback);

 Plymouth.SetUpdateStatusFunction(scroll_message_callback);


#----------------------------------------- Quit --------------------------------

fun quit_callback ()
{
 anim.sprite.SetOpacity (1);
  if (Plymouth.GetMode() == "shutdown") {
   motif.sprite.SetOpacity(1);
  }
}

Plymouth.SetQuitFunction(quit_callback);

Básicamente, el script se puede aplicar a cualquier tema, todo lo que tiene que hacer es proporcionar los nombres de archivo de las imágenes en la carpeta. Y cambiando algunas otras líneas para ajustar las imágenes en la pantalla. O lo que haces es copiar la parte necesaria, como digamos que quieres la parte de progreso, así que todo lo que tienes que hacer es copiar todo

----------------------------------------- Barra de progreso ------- -------------------------

Una vez que haya terminado de editar el mdv.script, asegúrese de sudo update-initramfs -u en su próximo arranque verá su nueva presentación.

Asegúrese de revisar los enlaces provistos en mi pregunta, son muy informativos y le permitirán comprender los scripts de Plymouth en muy poco tiempo.

Ahora, si ha hecho todo lo que dije aquí, el inicio de inicio debería mostrar mensajes de desplazamiento. Ahora sobre la parte truncada, actualmente estoy trabajando en ello, pero es un poco molesto tener que reiniciar mi máquina cada vez que hago algún cambio. ¿Es posible probar un proceso de arranque mientras estoy conectado como

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

Otra forma de probar Plymouth es copiando el comando anterior en un archivo de texto y agregando sudo plymouth update --status="your message" para tener más mensajes de desplazamiento. Luego haga el archivo ejecutable y ejecútelo en la terminal.

Espero que esto ayude a cualquiera que quiera editar su splash de Plymouth. ¡¡¡Buena suerte!!!

Sé que es un hilo viejo, pero creo que sé la respuesta sobre el truncamiento de texto o no. En mi themename.script (no el archivo themename.plymouth) uso dos variables.

1. NUM_SCROLL_LINES
2. LINE_WIDTH

Con estas variables puedo establecer cuántas líneas se mostrarán y cuánto durarán las líneas que se mostrarán. El script también tiene una función que trunca las líneas si son demasiado largas para mostrar.

Espero que esto sea útil para alguien.

Mi problema en opensuse 42.1 Leap es. plymouth no muestra mensajes de arranque, como si estuvieran escritos en /var/log/boot.log. Muestra las llamadas al sistema de servicios.

También edité / lib / lsb / init-functions de esta manera

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

o eso

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

Nada me funcionó. Alguien tiene una idea?

Aquí está el themename.script que uso

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);
