Как изменить plymouth ubuntu

Getting Started Guide

Editing Plymouth

You can edit Plymouth with a simple text editor for animations and images. This is Ubuntu version agnostic.

• Get Template
• Customize Template
• Set Custom Theme

Make a template

First you will get a template that covers all the basic aspects of a Plymouth. Change my-theme to your own personal them name.

sudo cp --recursive /lib/plymouth/themes/ubuntu-logo ~/themes/my-theme

Customize file names

Now you can change some names to help identify our theme from others.

sudo mv ubuntu-logo.plymouth my-theme.plymouth
sudo mv ubuntu-logo.script my-theme.script
sudo mv ubuntu-logo.grub my-theme.grub
sudo mv ubuntu_logo16.png my_theme16.png
sudo mv ubuntu_logo.png my_theme.png

Edit image files

Use your image editor of choice to alter the png images. I like GIMP for quick edits.

gimp my_theme.png my_theme16.png 
gimp progress_dot_on.png progress_dot_off.png 
gimp progress_dot_on16.png progress_dot_off16.png

Here is an example of my alterations:

Edit the configuration files.

1. Set up theme information file.

   gedit my-theme.plymouth
   

   Edit lines 2, 7, and 8 and change ubuntu logo to you theme name.

   [Plymouth Theme]
   Name=My Theme
   Description=A theme that features a blank background with a logo.
   ModuleName=script
   
   [script]
   ImageDir=/lib/plymouth/themes/my-theme
   ScriptFile=/lib/plymouth/themes/my-theme/my-theme.script
   

2. Start-up terminal color. (Optional)

   gedit my-theme.grub
   

   Change it from purple to something else.

   Edit line 1 with RGB color code.

   A good site to help you is Color-Hex. I am just going to make mine black.

   if background_color 0,0,0; then
     clear
   fi
   

3. The script file to apply theme changes

   gedit my-theme.script
   

   There is many different aspects to this file that you can change to customize your plymouth boot theme. If you wish to do more advanced changes you should study it. I am only showing how to change the background color, logo, and status indicator.

   Edit lines 169, 170, 174, and 180 to change the background gradient and images you edited earlier.

   Window.SetBackgroundTopColor (0.66, 0.66, 0.66);       #top 
   Window.SetBackgroundBottomColor (0.146, 0.146, 0.146); #bottom
   
   bits_per_pixel = Window.GetBitsPerPixel ();
   if (bits_per_pixel == 4) {
       logo_filename = "my_theme16.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 = "my_theme.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";
   }
   

Send your theme folder

cp --recursive ~/themes/my-theme /lib/plymouth/themes

Set Plymouth configuration to use theme.

sudo ln -sf /lib/plymouth/themes/my-theme/my-theme.plymouth /etc/alternatives/default.plymouth
sudo ln -sf /lib/plymouth/themes/my-theme/my-theme.grub /etc/alternatives/default.plymouth.grub

18.04+

sudo update-initramfs -u

Restart to watch it in action.

Plymouth is the application which provides the graphical «splash» screen when booting and shutting down an Ubuntu system.

Note that on Ubuntu, Plymouth is considered to be the «owner» of the console device (/dev/console) so no application should attempt to modify terminal attributes for this device at boot or shutdown.

Quick Facts

Plymouth:

• Uses KMS (Kernel Mode Setting) (where possible) and the framebuffer to set the screen resolution.
• Comprises 3 components:

  • A daemon (server) process called plymouthd
    

    • The daemon is responsible for the graphical display, animation and logging.

  • A client application called plymouth
    

    • The client sends commands to the daemon

  • A library libply.so to allow applications to be written to talk to the daemon
    

    • (The plymouth command is linked to libply.so for this reason).

• Supports themes.

• Is scriptable (see package plymouth-theme-script)

• Runs at system startup and system shutdown:
  • Boot

    • plymouthd is generally started in the initramfs
      

      • (see file /usr/share/initramfs-tools/scripts/init-top/plymouth)

    • plymouthd is stopped at the point the Display Manager is starting
      

      • (see Upstart job configuration file file /etc/init/plymouth-stop.conf).

  • Shutdown

    • plymouthd is started by Upstart
      

      • (see Upstart job configuration file file /etc/init/plymouth.conf).

• Writes a log to /var/log/boot.log.

Options

Daemon

plymouthd runs in one of four modes which are set by specifing the appropriate command-line option:

• —mode=boot

• —mode=shutdown

• —mode=suspend

• —mode=resume

This allows Plymouth to display potentially different content based on whether the system is starting or stopping.

Startup

The plymouthd daemon attempts to read the following files at startup (the first file it finds takes precedence over any other):

• General configuration

  • /etc/plymouth/plymouthd.conf (unused on Ubuntu)

  • /lib/plymouth/plymouthd.defaults (unused on Ubuntu)

• Splash Theme

  • /lib/plymouth/themes/default.plymouth

Splash Theme

Contents of /lib/plymouth/themes/default.plymouth:

  [Plymouth Theme]
  Name=Ubuntu Logo
  Description=A theme that features a blank background with a logo.
  ModuleName=script

  [script]
  ImageDir=/lib/plymouth/themes/ubuntu-logo
  ScriptFile=/lib/plymouth/themes/ubuntu-logo/ubuntu-logo.script

This tells plymouthd to use the «script» splash plugin. This plugin allows the graphical splash experience to be scripted using Plymouths own scripting language (hence the name).

The «script» splash plugin exists as /lib/plymouth/script.so (source code: src/plugins/splash/script/script.c)

• «ImageDir» tells plymouthd which directory contains the images used by the «Ubuntu Logo» theme.

• «ScriptFile» is the full path to the Plymouth script which creates the splash experience.

Testing

Checking Plymouth Can Run in the Initramfs

1. Add «break=init» to the kernel command-line and boot.

2. Chroot to the real filesystem:

   •     chroot /root

     Some warning messages will be displayed, but they can be ignored:

         bash: cannot set terminal process group (-1): Inappropriate ioctl for device
         bash: no job control in this shell

3. Start the daemon:

   •     plymouthd --tty=`tty` --mode=boot --kernel-command-line="quiet splash"

4. Check that the daemon is running:

   •     plymouth --ping && echo plymouth is running || echo plymouth NOT running

5. Tell the daemon to display the splash screen:

   •     plymouth show-splash

If this works, to exit the splash screen you’ll have to type the following «blind» (and note that backspace won’t work, but CONTROL-c will):

  plymouth exit

To shutdown your system:

1. Remount the disk read-only:

   •     mount -oremount,ro /

2. Power off the system.

Note that «shutdown -h now or «halt» cannot be used since Upstart is not running in this scenario.

Checking Plymouth Can Run Early in Boot

1. Add «init=/bin/sh» to the kernel command-line and boot.

2. A warning message will be displayed, but can be ignored:

   •     /bin/sh: 0: can't access tty: job control turned off

3. Start the daemon:

   •     plymouthd --tty=`tty` --mode=boot --kernel-command-line="quiet splash"

4. Check the daemon is running

   •     plymouth --ping && echo plymouth is running || echo plymouth NOT running

5. Tell the daemon to display the splash screen:

   •     plymouth show-splash

If this works, to exit the splash screen you’ll have to type the following «blind» (and not that backspace won’t work, but CONTROL-c will):

  plymouth exit

To shutdown your system:

1. Flush any pending data:

   •     sync;sync;sync

2. Remount disk read-only:

   •     mount -oremount,ro /

3. Power off the system.

Note that «shutdown -h now or «halt» cannot be used since Upstart is not running in this scenario.

Running Plymouth «post-boot»

You can experiment with Plymouth after your system has booted. To start the Plymouth daemon:

1. Boot system and login as usual

2. [RECOMMENDED] Install plymouth-x11 package (allows you to see the boot screen in an X11 window)

   • sudo apt-get install plymouth-x11

3. Start a terminal (such as gnome-terminal)

4. Start the Plymouth daemon by running the following:

   • sudo plymouthd —debug —tty=`tty` —no-daemon

Plymouth is now running, so we can have some fun:

• To check if Plymouth really is running:
  

  • sudo plymouth —ping && echo plymouth is running || echo plymouth NOT running

• To show a message on our «boot» screen

  1. Start another gnome-terminal terminal/tab

  2. Run the following to show the Plymouth window:
     

     • sudo plymouth show-splash
  3. Display a message

     • sudo plymouth message —text=»hello world»

• A slightly more useful example
  1. Show the splash screen

     • sudo plymouth show-splash

  2. Stop the graphical progress indicator

     • sudo plymouth pause-progress

  3. Display a message

     • sudo plymouth message —text=»pausing boot — press ‘c’ or space bar to continue»

  4. Wait for the user to type either ‘c’, ‘C’ or space (no return required)

     • sudo plymouth watch-keystroke —keys=»cC » —command=»tee /tmp/c_key_pressed»

  5. Change the on-screen message

     • sudo plymouth message —text=»resuming boot»

  6. Resume the graphical progress indicator

     • sudo plymouth unpause-progress

Note that when you run the «show-splash» command, two windows pop up. This is because Plymouth simulates a dual-monitor setup.

To stop the Plymouth daemon:

• sudo plymouth —quit

Debugging

This section is for advanced users only.

Toggling to Traditional Text-based Boot

If you want to see the text-based boot messages (which use the Plymouth «details» plugin, press the ESCAPE key at any point when Plymouth is running. Note that the ESCAPE key acts as a toggle, so you can keep switching between graphical and text mode as required.

To have the boot start in «text mode» as early as possible, remove «splash» from the kernel command-line in grub.

To make the change permanent, update /etc/default/grub and run «sudo update-grub».

Enabling Debugging

You can set Plymouth to overlay internal debug messages (which will also be logged to a file) by adding the following command-line option to grub:

• plymouth:debug

For example, if you are running Ubuntu Natty (11.04) or Oneiric (11.10):

1. Power on system.

2. Hold down the CONTROL key until the Grub boot menu appears.

3. Type «e» to edit the default kernel command-line.

4. Use the arrow keys to go to the end of the line which starts «linux /boot/vmlinuz …».

5. Add a space character, followed by «plymouth:debug».
   Notes:

   • If you’re interested in the overall boot, you may wish to remove the «quiet» keyword too)

6. Type CONTROL+x to boot

7. Once the system has booted, you can view all the Plymouth debug output in file var/log/plymouth-debug.log.

For older releases such as Maverick (10.10), hold down the SHIFT key rather than the CONTROL key to access the grub boot menu.

Notes:

• If you are using the live CD, the process is slightly different:
  1. Power on system
  2. Hold down the SHIFT key until ISOLINUX «boot:» prompt appears

  3. Type, «live plymouth:debug»

Plymouth Logs

Plymouth will log all output sent to the console to a file. By default, the data is logged to file /var/log/boot.log. If Plymouth is running in debug mode, debug messages are logged to /var/log/plymouth-debug.log.

Note that plymouthd buffers all messages until told that the disk partition on which the logs are to be written (in other words the partition containing /var/log/) is writeable.

The Upstart job /etc/init/plymouth-log.conf is used to accomplish this by calling:

  plymouth update-root-fs --read-write

Tips

• Take care if you add «console=» options to your kernel command line since plymouthd will honour those over its own

  • «—tty=TTY» option!

Additional

«plymouth ask-question»

Used to prompt the user for an answer, echoing the answer text as it is typed. The answer is by default echoed to stdout to allow it to be piped to another command which expects to read the password on its stdin. Example:

  plymouth ask-question --prompt "what is your name? " |
    command-to-process-answer --read-from-stdin

Similar functionality is provided by a combination of «plymouth message» and «plymouth watch-keystroke».

«plymouth ask-for-password»

Used to prompt the user for a password securely (password text is not echoed). The password the user enters is by default echoed to stdout to allow it to be piped to another command which expects to read the password on its stdin. Example:

  plymouth ask-for-password --prompt "specify password: " |
    command-to-read-password-and-do-secret-things --read-from-stdin

Special FSCK messages

The Ubuntu Plymouth theme supports a «special» message that allows mountall to display fsck progress messages («fsck is 20% complete»). You can make use of this functionality by using a special message format:

  sudo plymouth --update=fsck:sda1:27

This will display a message like:

  Checking disk 1 of 1 (27% complete)

Plymouth — свободный графический экран загрузки для Linux. Приложение использует Direct Rendering Manager и Kernel Mode-Setting.

Разработка Plymouth началась в мае 2007 года под руководством Рэя Строда, но стал развиваться лишь в 2008 году, когда был внедрён в Fedora 10. Позднее он был внедрён в Mandriva Linux 2010, сменил Usplash и XSplash вUbuntu с версии 10.04.

Можно установить стандартную тему любого из дистрибутивов набрав в терминале

apt-cache search plymouth-theme-

и увидим вот такую картину

Чтобы установить любую из этих тем нужно набрать в терминале

sudo apt install plymouth-theme-ubuntu-gnome-logo

sudo apt install plymouth-theme-ubuntu-gnome-text

И изменяем с помощью

sudo update-alternatives --config default.plymouth

Нам предложат выбрать из трех вариантов. Выбираем нашу установленную тему цифрой и далее обновляем конфигурацию

sudo update-initramfs -u

А все очень просто.

На сайте gnome-look.org слева в разделе «Plymouth Themes», есть очень большое количество тем, но они за 2015 год, то есть для Ubuntu 14.04/Linux Mint 17, но мы можем изменить нашу скачанную тему для нашей Ubuntu 16.04/Linux Mint, сейчас объясню почему, в Ubuntu 14.04/Linux Mint 17 по умолчанию темы plymouth были в директории /lib/plymouth/themes/, но с приходом Ubuntu 16.04 все немного изменилось, и сейчас темы расположены по адресу /usr/share/plymouth/themes/, поэтому нам нужно изменить для начала нашу тему.

Итак Вы выбрали и скачали тему(я скачал тему под названием Anon-Pun2), идем в директорию куда Вы скачали тему, и правой кнопкой мышки нажимаем и выбираем «Извлечь сюда», после извлечения заходим в папку с темой и находим там файл под названием «название темы.plymouth»(в моем случае это — Anon-Pun2.plymouth), открываем с помощью любого редактора(например gedit)

[Plymouth Theme]
Name=Anon-Pun2
Description=A theme that features a background with a logo.
ModuleName=script

[script]
ImageDir=/lib/plymouth/themes/Anon-Pun2/
ScriptFile=/lib/plymouth/themes/Anon-Pun2/Anon-Pun2.script

Вот что мы видим, а теперь просто берем и меняем пути с /lib/ на /usr/share/

[Plymouth Theme]
Name=Anon-Pun2
Description=A theme that features a background with a logo.
ModuleName=script

[script]
ImageDir=/usr/share/plymouth/themes/Anon-Pun2/
ScriptFile=/usr/share/plymouth/themes/Anon-Pun2/Anon-Pun2.script

Нажимаем «Сохранить», все больше нам не понадобится этот файл.

Чтобы дальше нам быстрее работать, открываем терминал и переходим в директорию загрузки

cd Загрузки/Anon-Pun2-Boot/

По-умолчанию в теме что я скачал двойная вложеность(может у Вас и не будет), то есть после распаковки у меня есть директория Anon-Pun2-Boot, а уже в ней сама тема под названием Anon-Pun2.

И копируем(почему копируем? можем просто переместить, ну на всякий случай) в папку с темами plymouth

sudo cp -a Anon-Pun2 /usr/share/plymouth/themes

далее обновляем дефолтные темы

sudo update-alternatives --install '/usr/share/plymouth/themes/default.plymouth' default.plymouth /usr/share/plymouth/themes/Anon-Pun2/Anon-Pun2.plymouth 100

sudo update-alternatives --config default.plymouth

Нажимаем цифру нашей темы

sudo update-initramfs -u

И последняя команда обновит конфигурацию системы

А если вы установили драйвер Nvidia, то у вас наверняка поламалась заставка загрузки системы, поэтому предлагаю прочитать статью «Восстановить заставку Plymouth после установки проприетарного драйвера Nvidia«.

Вот и все, надеюсь я кому-то помог в этом простом решении проблемы.
