Dark Splash

A minimal dark boot splash theme for Linux (Plymouth) with a glowing logo, loading spinner, progress bar, and a styled password prompt for encrypted disks.

Features

• Dark gradient background with a cyan → violet accent
• Animated spinner and pulsing logo glow
• Password box with lock icon and dot bullets (shown when the disk asks for a passphrase)
• Boot progress bar and status messages
• All images generated from one Python script, so recoloring is easy

Install

git clone https://github.com/<your-username>/dark-splash.git
cd dark-splash
chmod +x install.sh preview.sh
sudo ./install.sh

Your kernel boot line needs quiet splash. On GRUB, set this in /etc/default/grub:

GRUB_CMDLINE_LINUX_DEFAULT="quiet splash"

then run sudo update-grub and reboot.

Preview without rebooting

Switch to a TTY (Ctrl+Alt+F3), log in, then:

sudo ./preview.sh

Change the colors

Edit the palette at the top of build-assets.py, then:

pip install pillow numpy
python3 build-assets.py
sudo ./install.sh
