Depending on the resolution and size of your monitor the usplash image with Elyssa may not fill the whole screen during boot. Usplash is the screen that shows the progress during the boot process. This has been tested and works for my lcd with a native resolution of 1280x1024.
Open Terminal and enter the following
gksu gedit /etc/usplash.conf
Change the xres setting to xres=800 and the yres setting to yres=640 and then save the file and close.
From the terminal enter the following
sudo update-initramfs -u
Restart the computer.
It may take a few attempts with different resolutions if it does not work right away.
