I wanted to know how to customize the splash screen in Ubuntu 13. I have tried to install Plymouth Manager but when I run sudo apt-get update it says it was unable to fetch http://ppa.launchpad.net/mefrio-g/plymouthmanager/ubuntu/dists/raring/main/binary-i386/Packages. I opened the address in Firefox but it didn't open. Also I would like to know where the files for the Ubuntu Logo, Splash Screen Background, etc. are located (to customize them). In previous versions they were located at usr/share/images. I am running Ubuntu 13 Raring Ringtail on VMWare Player. The host is an Acer 5600U running Windows 8. Thnx.
Follow this: Choosing a GRUB 2 Background Image
After finished the installation, the splash images' in the folder /boot/grub. You can copy the images you like into the folder, keep note the priority of the images as the link: Image Priority Do remember to update grub after every changing splash images: sudo update-grub
Plymouth, Ubuntu logo you can find out: /lib/plymouth/themes. This link's also help for Plymouth knowledge: Get your precious Plymouth splash screen back!
I've installed Plymouth Manager on Ubuntu 13.04, but the PPA isn't working. You have to download the .deb file and install it.
