Before you can use Splashy, you should enable Kernel Mode Setting. Please refer to the specific instructions for ATI cards, Intel cards or Nvidia cards. All of these require you to rebuild your kernel image. You will also have to do that later on in this article, so you may wish to skip that step for now.
If you do not have KMS you will need to use framebuffer instead. Uvesafb is recommended. Of all the three the regular framebuffer is the only one that does not support custom resolutions (including wide screen splashes).
Including Splashy in initramfs
The kernel command line
You now need to set quiet splash as you kernel command line parametres in your bootloader. The following is an example for Grub2 and Template:Filename (the legacy Grub and Lilo follow the same pattern):
linux /boot/vmlinuz-linux root=/dev/... ro quiet splash
The folder name is the theme name. Now change the theme to the one you want, eg.: Template:Cli
Rebuild your kernel image with: Template:Cli
GNOME will not shut down
Problem: You are using Gnome, and starting GDM as a daemon, Splashy causes Gnome to not be able to properly shutdown/reboot.
