Plymouth Manager is a GUI tool to manage the plymouth splash screen at Ubuntu start-up and shutdown. Ubuntu has few plymouth themes in its official repository, and by default doesn’t have a plymouth manger installation. Here is how to install latest plymouth manager and plenty of plymouth themes from an untrusted PPA.

Mario Guerriero’s ppa provides lastest stable plymouth-manager packages and also a mass of plymouth themes for Ubuntu 11.10 Oneiric/11.04 Natty/10.10 Maverick/10.04 LTS/Linux Mint.
