¿Cómo lograr que Plymouth muestre los mensajes de arranque al arrancar?

19

Me gustaría saber cómo crear un splash para Ubuntu Maverick con los mensajes de inicio que se muestran cuando reinicio, 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 inicio.

Este es el tema que me gustaría editar:

y me gustaría algo como esto:

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

Pude encontrar este sitio web que tiene mucha información útil, pero me cuesta mucho entenderlo. no he hecho ningún script antes!

Crea tu propio toque pantalla con desplazamiento de mensajes de inicio

Creación de secuencias de comandos de Plymouth

y este es otro sitio web que puede ayudar con la creación de scripts

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);

De acuerdo, hice más búsquedas 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 debes leer para obtener la esencia de lo que estamos haciendo. (Estaba comparando el guión con el guión de mi splash para entender qué es qué, recomiendo hacerlo si alguien quiere seguir mis pasos).   Creación de scripts de Plymouth De acuerdo, este enlace tiene 2 páginas para ver qué hacer. Resulta que estaban buscando lo mismo que yo, que es dirigir los mensajes de arranque al salpicón de Plymouth, donde ya tengo un logotipo giratorio, fondo, barra de progreso.

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

        fi
    fi
    log_action_end_msg_post "$@"
}

Hasta ahora no he podido enviar los mensajes a Plymouth, pero obtuve una mejor comprensión de cómo funciona el scripting de Plymouth.

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

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

Aquí está mi trabajo hasta ahora.

primero tienes que hacer que las funciones init envíen mensajes a Plymouth haciendo que se vea así (ve a través de cada línea para ver las diferencias y copia la línea que corresponde al envío de Plymouth):

Básicamente, la secuencia de comandos se puede aplicar a cualquier tema, todo lo que tienes 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 la que digamos que quieres la parte de progreso, así que todo lo que tienes que hacer es copiar todo de

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

hasta

----------------------------------------- Actualización de estado ---- ----------------------------

Una vez que haya terminado de editar el mdv.script, asegúrese de sudo update-initramfs -u y en tu próximo arranque verás tu nuevo toque.

Asegúrese de revisar los enlaces proporcionados en mi pregunta. Son muy informativos y le permitirán comprender las secuencias de comandos de plymouth en poco tiempo.

Ahora, si has hecho todo lo que dije aquí, el inicio de arranque debería mostrar los 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 copiar el comando anterior en un archivo de texto y agregar sudo plymouth update --status="your message" para que se desplacen más mensajes. Luego, haga que el archivo sea ejecutable y ejecute en la terminal.

Espero que esto ayude a cualquier otra persona que desee editar su splash de Plymouth. ¡Buena suerte!

Sé que es un hilo antiguo, pero creo que sé la respuesta sobre el truncamiento del texto o no. En mymename.script (no en el archivo themename.plymouth) utilizo dos variables.

1. NUM_SCROLL_LINES
2. LINE_WIDTH

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

Espero que esto sea útil para alguien.

Mi problema en opensuse 42.1 Leap is. plymouth no muestra los mensajes de inicio, como si estuvieran escritos en /var/log/boot.log. Muestra las llamadas a servicios systemd.

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 funcionó para mí. ¿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);
