我想知道如何为 Ubuntu Maverick 创建一个启动画面，并在启动时显示启动消息以及进度条和旋转的徽标。
或者，如果可能的话，如何编辑已经有旋转徽标和进度条的启动画面，并向其中添加启动消息。
这是我想要编辑的主题：
我想要这样的东西：
或者这个，这就是我想要创建的确切的启动画面：
我能够找到这个网站，它有很多有用的信息，但我很难理解其中的一些信息。以前没有做过任何脚本！
这是另一个可以帮助编写脚本的网站
这是启动画面中进度条的脚本：
#----------------------------------------- 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);
好的，我做了更多的搜索，并且能够更多地了解普利茅斯。
这些是我认为有用的网站。 普利茅斯主题指南 这篇文章有四个部分，你必须通读它们才能了解我们正在做的事情。（我正在将他们的脚本与我的 splash 脚本进行比较，以了解哪个是哪个，如果有人要追随我的脚步，我建议这样做。） 普利茅斯脚本 好的，这个链接有 2 页，必须浏览一遍才能明白该怎么做。结果发现他们想要的和我是一样的，也就是将启动消息直接发送到 Plymouth 启动画面，而我已经在那里有旋转的徽标、背景和进度条。
因此我必须编辑我的/lib/lsb/init-functions文件，并通过添加此段落使其能够将启动错误/成功等消息发送到 Plymouth

到目前为止，我还不能将信息传递到普利茅斯，但我确实更好地了解了普利茅斯脚本的工作原理！
我不知道我还能做些什么才能让它发挥作用！希望这里有人能帮助我
哦，这是我的脚本版本溅我正在努力。

好的，我已提供几乎所有需要的信息，如果有人熟悉这些信息，请告诉我我缺少什么才能将启动消息传递到普利茅斯。谢谢
答案1
好吧，我已经连续 4 天研究这个问题了，我几乎完全解决了。到目前为止，我能够让 Plymouth 启动并显示消息，但不幸的是消息被截断了。现在我正在尝试调整脚本，但我不知道问题出在 /lib/lsb/init-functions 脚本还是 /lib/plymouth/themes/"theme-name"/mdv.script 中。
这是我迄今为止的工作。
首先你必须让 init 函数向 Plymouth 发送消息，如下所示（逐行查看差异并复制与 Plymouth 发送相对应的行）：

基本上，该脚本可以应用于任何主题，您所要做的就是提供文件夹中图像的文件名。并更改其他几行以调整屏幕上的图像。或者您要做的就是复制必要的部分，例如，假设您想要进度部分，因此您所要做的就是从
- - - - - - - - - - - - - - - - - - - - - 进度条 - - - - - - - - - - - - - - - -
直到

编辑完 mdv.script 后，请确保sudo update-initramfs -u
在下次启动时看到新的启动画面。
请务必查看我的问题中提供的链接，它们非常有用，可以让您立即了解普利茅斯脚本。
现在，如果您已经完成了我在这里所说的一切，您的启动画面应该会显示滚动消息。现在关于截断部分，我目前正在处理它，但每次我进行一些更改时都必须重新启动我的机器，这有点烦人。是否可以在登录时测试启动过程喜欢
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
测试 Plymouth 的另一种方法是将上述命令复制到文本文件中，并添加sudo plymouth update --status="your message" 更多消息以滚动显示。然后使文件可执行并在终端中运行。
希望这能帮助其他想要编辑普利茅斯溅水的人。祝你好运！！！
答案2
我知道这是一个老话题，但我想我知道关于文本截断的答案。在我的 themename.script（不是 themename.plymouth 文件）中，我使用了两个变量。
1. NUM_SCROLL_LINES
2. LINE_WIDTH
使用这些变量，我可以设置要显示多少行以及要显示多少行。如果行太长而无法显示，该脚本还有一个功能可以截断这些行。
我希望这对某些人有帮助。
我在 opensuse 42.1 Leap 中遇到的问题是。plymouth 不显示启动消息，就像它们被写入 /var/log/boot.log 一样。它显示 systemd 对服务的调用。
我也以这种方式编辑了 /lib/lsb/init-functions
if [ -x /usr/bin/plymouth ]; then
/usr/bin/plymouth update --status="$@"
fi
或者那个
[ -x /usr/bin/plymouth ] && /usr/bin/plymouth update --status="$@"
对我没什么用。有人有办法吗？
这是我使用的 themename.script
