Branding

NOTE

It is unclear yet if local versions of "EU OS" will be branded as "EU OS" or as e.g. "University Fantasia OS". So the following aspects just explain how branding works technically, but do not take a position whether image customisation should lead to the removal of the "EU OS" branding.

Linux in general offers ways to add Branding (Corporate Identity).

Wallpapers

Wallpapers are generally stored under /usr/share/wallpapers in distinct folder per wallpaper. KDE offers different configuration files to set those wallpapers:

1. default wallpapers for new users (does not impact existing users)
2. user wallpaper of an existing user (set in the users ~/.config folder)

Plymouth

Plymouth allows to change the boot srceen shown between powering on and the login screen.

Generally, the distro default configuration for Plymouth is stored in /usr/share/plymouth/plymouthd.defaults that is part of the package plymouth on Fedora. Those settings can be overwritten with /etc/plymouth/plymouthd.conf
