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
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
Si alguien quiere probar el chapoteo sin reiniciar, este es un método fácil 'Instale el paquete plymouth-x11 Ejecute sudo plymouthd; sudo plymouth --show-splash; dormir 10; sudo killall plymouthd ' askubuntu.com/questions/51078/…

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

freedesktop.org/wiki/Software/Plymouth/Scripts otra página de secuencias de comandos de Plymouth. ayuda mucho si no sabes javascript o C.
