Monoarch is a theme for Plymouth which exhibits a monochrome white on black look and feel. It displays the Arch Linux logo and a spinner.

AUR Package

The AUR package for this theme is plymouth-theme-monoarch. You may use your favourite AUR helper or proceed with manual installation as described here.

The package does not alter your Plymouth configuration, you have to change the theme manually. In order to do so, type:

# plymouth-set-default-theme -R monoarch

And you're done.

Installation

Files should be placed in the Plymouth themes directory, which is usually /usr/share/plymouth/themes. You may install the theme by simply cloning the repository:

# cd /usr/share/plymouth/themes/ 
# git clone https://github.com/farsil/monoarch.git 

Remember to change the Plymouth theme:

# plymouth-set-default-theme -R monoarch

Removal

Simply remove the directory:

# rm -rf /usr/share/plymouth/themes/monoarch

Remember to change your theme again otherwise Plymouth will fall back to its default one.

Using with distributions other than Arch Linux

Nothing prevents you from doing that. If you want to replace the Arch Linux logo with your favourite distribution's, you may want to change the images/logo.png file to suit your liking.
