How to configure splash screen after plymouth

I have configured my splash screen for plymouth - and it works perfectly. I've also configured the display manager (I'm using gdm). In between these two I get a very brief splash screen - a kind of swirl of multi-coloured ubuntu like colours. Where does this splash screen get set, and how do I change it?

Edit: Here is a video of my boot sequence, showing the screen in question: http://youtube.com/watch?v=fMM6I-c7ga8

Solution 1:

I'm going out on a limb here.

If the problem that you're having with Plymouth has anything to do with proprietary ATI / Nvidia graphics drivers, try this script.

Also there are two Plymouth Managers that my help you

A GUI called Splashscreen Manager, and the other GUI is called Plymouth Manager

Note:Plymouth does not reliably work with nVidia drivers and during bootup a blank screen may result for several seconds.
