ubuntu splash screen

How to change the gnome splashimage.
1. Put the splash image you want in "png" format and store it in /usr/share/pixmaps/splash. (You can use Nautilus or the "cp" or the "mv" command from the terminal window if you want. Just remember to use "sudo" before your command. )
2. Press ALT-F2 then at the prompt type "gconf-editor" (without the quotes).
3. Click on "apps" then "gnome-session" then "options".
4. To the right of the Name "splash_image" double click on the Value "splash/ubuntu-splash.png".
5. Change "splash/ubuntu-splash.png" to reflect your new splash image: "splash/newsplash.png".
6. Click on "File" then "Quit".
7. Logout then login in again to see your new splashimage.
