Installation

Simply place the content of this repo in /usr/share/plymouth/themes/chain and use plymouth-set-default-theme chain to set the new theme. In some distributions like Ubuntu, changing the Plymouth theme must be done with update-alternatives.

Once the theme changed, you can use the following command to test it :

plymouthd; plymouth show-splash; sleep 3; plymouth ask-for-password; sleep 2; plymouth quit

If you are satisfied with the result, you can rebuild your initrd.

You can use this entry in Archwiki for more information about settting up Plymouth and changing themes.

git clone https://aur.archlinux.org/plymouth-theme-chain.git
cd plymouth-theme-chain
makepkg -si

# or using AUR helper

Then select the theme usin plymouth-set-default-theme. The -R option ensures that it is rebuilt (otherwise manually run mkinitcpio -P):

Customization

To help better adapt the plymouth theme to different computers, distros and rices, some elements are made customizable.

Positions and texts

The file chain.script exposes a Configuration section in wich the position of individual elements can be customized, as well as the font in use and the different texts.

Available customizations:

• the main font used for the boot message
• the secondary font used for the password prompt and the progress reports
• the position of the animation
• the position of the boot message
• the position of the progress bar
• the position of the progress messages
• the position of the lock icon
• the position of the password prompt
• the placeholder text for the password prompt
• the character used to obfuscate the password (bullet)

Colors

The color palette of this theme consists of three following components:

• the main color for animation, progress bar, icons, boot message and password prompt
• the secondary color for password input background, progress bar background and the progress messages
• the background color.

For simplicity, the change-color.sh script is provided with the following usage:

Usage: ./change-color.sh <mode> <color>

The color must be a 6 digits hexadecimal code with a leading # (e.g "#ABC123")

Mode can be one of the following
 background       Set <color> as background color
 main             Set <color> as main theme color
 secondary        Set <color> as secondary color

Be aware that ImageMagick is needed to replace the colors of the animation and other graphical elements.
