I installed Kubuntu on my Ubuntu 12.04 installation... big mistake!

It has now changed my boot screen (boot prior to lightdm login screen)

How can I restore this back to Ubuntu login?

Nvidia drivers!

Found a solution here:

sudo update-alternatives --config default.plymouth

sudo update-initramfs -u

Had to restart a couple of times, but all reset.

I did these changes and restarted my system (many times) but still the problem exists. I removed plymouth-theme-kubuntu-text and plymouth-theme-kubuntu-logo packages as well. Now I am getting only purple screen (with no dots and no ubuntu image or text). I have ATI graphic card and using default graphic drivers. please help – mac Sep 6 '12 at 9:22
After 5 days, all of a sudden it worked! Yeah true, had to restart a couple of times ;) Patience, huh :) But still wondering how did it work suddenly :P – mac Sep 11 '12 at 7:17
Not sure if it worked bcz I have applied this fix as well echo FRAMEBUFFER=y | sudo tee /etc/initramfs-tools/conf.d/splash – mac Sep 14 '12 at 8:21

You can do the same thing a little easier

sudo apt-get install --reinstall plymouth-theme-ubuntu-logo

You can completely remove the Kubuntu Boot Screen by removing the plymouth-theme-kubuntu-logo and plymouth-theme-kubuntu-text packages.

Type these in the terminal to remove those packages:

sudo apt-get --purge remove plymouth-theme-kubuntu-text
sudo apt-get --purge remove plymouth-theme-kubuntu-logo

Ignore it if the terminal can't find the plymouth-theme-kubuntu-text package.

These work for me:

sudo update-alternatives --get-selections | grep plymouth 
sudo update-alternatives --config default.plymouth
sudo update-alternatives --config text.plymouth
sudo update-initramfs -u
