更改 18.04 LTS 的启动徽标

Question

默认情况下，Ubuntu 18.04 的启动徽标使用/usr/share/plymouth/themes/ubuntu-logo/ubuntu-logo.png脚本/usr/share/plymouth/themes/ubuntu-logo/ubuntu-logo.script

该脚本的部分内容如下

    bits_per_pixel = Window.GetBitsPerPixel ();
if (bits_per_pixel == 4) {
    logo_filename = "ubuntu-logo16.png";
    progress_dot_off_filename = "progress-dot-off16.png";
    progress_dot_on_filename = "progress-dot-on16.png";
    password_field_filename = "password-field16.png";
    question_field_filename = "password-field16.png";
} else {
    logo_filename = "ubuntu-logo.png";
    progress_dot_off_filename = "progress-dot-off.png";
    progress_dot_on_filename = "progress-dot-on.png";
    password_field_filename = "password-field.png";
    question_field_filename = "password-field.png";

通过理解上述脚本内容来更改启动徽标。我们需要用具有相同名称的自定义文件替换文件ubuntu-logo16.png。ubuntu-logo.png

您可以使用命令行轻松完成此操作。

~/Downloads当我的自定义图像带有boot.png名称时的示例命令行

cd /usr/share/plymouth/themes/ubuntu-logo
sudo mv ubuntu-logo.png ubuntu-logo.png.bak
sudo mv ubuntu-logo16.png ubuntu-logo16.png.bak
cd ~/Downloads
sudo cp boot.png /usr/share/plymouth/themes/ubuntu-logo/ubuntu-logo.png
sudo cp boot.png /usr/share/plymouth/themes/ubuntu-logo/ubuntu-logo16.png

自定义开机logo图片建议：
图片格式：.png
