Gostaria de saber como criar um splash para o Ubuntu Maverick com mensagens de inicialização sendo exibidas quando eu inicializar, bem como uma barra de progresso e um logotipo giratório.
Ou, se possível, como editar um splash que já tenha um logotipo giratório e uma barra de progresso e adicionar mensagens de inicialização a ele.
Este é o tema que eu gostaria de editar:
e eu gostaria de algo assim:
ou este, que é o splash exato que eu quero criar:
Consegui encontrar este site, ele tem muitas informações úteis, mas estou tendo dificuldades para entender algumas delas. não havia feito nenhum script antes!
Crie sua própria tela inicial com rolagem de mensagens de inicialização
e este é outro site que pode ajudar com scripts
este é o script para a barra de progresso no 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, então pesquisei muito mais e pude aprender um pouco mais sobre Plymouth.
esses são os sites que eu achei úteis. Guia de temas de Plymouth Há quatro partes nesse artigo que você precisa ler para entender o que estamos fazendo. (Eu estava comparando o script deles com o script do meu splash para entender o que é o que, recomendo fazer isso se alguém quiser seguir meus passos.) Script em Plymouth Ok, este link tem duas páginas que precisavam passar por eles para entender o que fazer . Acontece que eles estavam atrás da mesma coisa que eu, que é direcionar as mensagens de inicialização para o splash de Plymouth, onde eu já tenho um logotipo giratório, fundo, barra de progresso.
Então eu tive que editar meu /lib/lsb/init-functionsarquivo e torná-lo para que ele enviasse o erro de inicialização / sucesso, etc mensagens para Plymouth adicionando este parágrafo
# SEND MESSAGES TO PLYMOUTH

Até o momento, não consegui transmitir as mensagens para Plymouth, mas entendi melhor como os scripts de Plymouth funcionam!
Não sei o que mais devo fazer para dar certo! esperando que alguém aqui possa me ajudar

Se alguém quiser testar o splash sem reiniciar, é um método fácil 'Instale o pacote plymouth-x11 Execute sudo plymouthd; sudo plymouth --show-splash; dormir 10; sudo killall plymouthd ' askubuntu.com/questions/51078/...

Ah, e outra coisa que devo mudar GRUB_CMDLINE_LINUX_DEFAULT = "quiet splash" para GRUB_CMDLINE_LINUX_DEFAULT = "splash" para que as mensagens sejam exibidas?

freedesktop.org/wiki/Software/Plymouth/Scripts outra página de script do plymouth. isso ajuda muito se você não sabe qualquer javascript ou C.
