Plymouth, on certain conditions does not appear. This happens because Ubuntu has a little bug in your graphics card. This bug usually does not arise when we run ubuntu as a live CD or live USB. But when it was installed, this bug appeared. This bug is present in ubuntu 10:04. I think ubuntu will fix this bug on ubuntu 10:10. Apparently I thought wrong, this bug is still there.


There are some tricks to overcome this. What we need is a terminal.


Enter the following code in terminal

sudo su
echo FRAMEBUFFER=y > /etc/initramfs-tools/conf.d/splash
update-initramfs –u
exit

After that, restart your ubuntu. and see what happens. Plymouth will look like the following picture

If Plymouth is still not appear, it means this method does not apply to you.
