I recently moved from Kubuntu to Ubuntu (Personaly KDE Stuff Look better under Unity/Gnome than Gnome Stuff Looked Under KDE) and got all the K relics out but one thing (and it bothers me a Bit) on startup it still is blue with 'Kubuntu', and the little white/blue dots. How would I change this to be Ubuntu's default (orange-brown saying 'Ubuntu' with orange/white dots)?
Splashy also has trouble istalling.

I don't have the answer to your question, but I installed Kubuntu, then added LXDE and removed all the KDE stuff (or so I thought), yet I also have the Kubuntu splash screen. I figure it's not worth the effort to hunt down and change. YMMV.

I no longer use Ubuntu but believe that you can manually put anything on there by finding the plymouth theme you are using in /lib/plymouth/themes and just changing the image there but using the same name.

You should probably check synaptic for plymouth themes and see if the Ubuntu theme is installed.

If you check the man pages for plymouth or plymouth-themes you should find a simple command to chaange the themes. I just don't know it off hand. One of those "alternatives" commands.

All I have on record here is how you changed the theme before they got that stuff straight back in 10.04-testing.

I always changed the image in the file manually and either used the default images name or edited the script for the theme to match my image. That way I could use my wallpaper.

A quick search on plymouth at sympatic shows that the Ubuntu themes come with ubuntu-desktop, you just need to remove the earlier one (eg Kubuntu).
