Ubuntu – How to change splash screen Ubuntu back

splash screen is configured by the alternatives system... you can get a list of available plymouth themes by doing: update-alternatives --list default.plymouth

You can then change the current plymouth theme by doing sudo update-alternatives --set default.plymouth /lib/plymouth/themes/kubuntu-logo/kubuntu-logo.plymouth

The alternative way of getting Kubuntu splash it to remove package xubuntu-plymouth-theme.

To change the login screen you can either run sudo dpkg-reconfigure gdm and choose kdm as mentioned in another comment or remove gdm which should set kdm as default display manager.

After searching and searching online I've found the answer to this problem and the solution is quite simple.

Apparently it's because the graphic drivers don't load quickly enough during the booting sequence so by the time the graphic drivers are ready booting has almost finished and thus either no plymouth screen is shown or a very quick fast of it is seen.

So the solution I found and it works is to add a simple line to the following file.

gksu gedit /etc/initramfs-tools/conf.d/splash

then add:

FRAMEBUFFER=y

Save the file, and then :

sudo update-initramfs -u -k all

This command will update the initial ramdisk containing the drivers needed by the kernel at boot time. The parameter -k all updates all of them if you have more than one kernel installed. Reboot and all is well.

This works in ubuntu 12.04 too.

Hope this helps anyone who is missing the lovely Ubuntu boot screen.
