Comment 3 for bug 609845

Patrick,
You can remove "splash" and "quiet" from your grub menu entry.
1) Edit /etc/default/grub as root*. You should see a line that looks like: GRUB_CMDLINE_LINUX_DEFAULT="quiet splash". Comment this line out and save.
2) Run: sudo update-grub
* There are many ways to edit a file as root. I prefer Alt+F2, type kdesudo kate, open desired file.

Unfortunately, this disables the splash for all linux entries.

You could alternatively, create a custom entry to boot from, which has no splash:
1) Create a new file, 09_kubuntu:
2) Copy-and-paste from 40_custom (or simply rename 40_custom to 09_desiredfilename):
#!/bin/sh
exec tail -n +3 $0
3) Open /boot/grub/grub.cfg. Find your menu entry that you prefer to boot from with no splash.
4) Copy this menu item to your new 09_kubuntu
5) Run: sudo update-grub

Example:
#!/bin/sh
echo 'Adding splashless Kubuntu, with Linux 2.6.32-24-generic' >&2
exec tail -n +3 $0
# This file provides an easy way to add custom menu entries. Simply type the
# menu entries you want to add after this comment. Be careful not to change
# the 'exec tail' line above.
#if [ "x${GRUB_DISTRIBUTOR}" = "x" ] ; then
# OS=GNU/Linux
#else
# OS="${GRUB_DISTRIBUTOR}"
# CLASS="--class $(echo ${GRUB_DISTRIBUTOR} | tr '[A-Z]' '[a-z]' | cut -d' ' -f1) ${CLASS}"
#fi
