I have Ubuntu 10.04 .

Just after installing Ubuntu, I installed all the desktop packages except lubuntu.

Then when I restarted the computer, Ubuntu shows the Kubuntu boot screen when I restart the computer.

Next I uninstalled all the desktop packages except ubuntu-desktop. The boot screen changed back to the Ubuntu one.

So how can I retain the Ubuntu boot screen while keeping the other desktop packages?

Open a terminal and type:

sudo dpkg-reconfigure gdm

Then it will ask you to choose the default login manager. Use TAB to move between options.

Doesn't that change the login manager, rather than the boot screen? – Mechanical snail May 18 '12 at 10:06
Apparently. Use sudo update-alternatives --set default.plymouth /lib/plymouth/themes/xubuntu-logo/ubuntu-logo.plymouth. – aquaherd May 18 '12 at 20:17
Does it work in Ubuntu 12.04? – Emerson Hsieh May 18 '12 at 22:13
Yes. However, it might help to do a sudo update-initramfs -a to tell the initial ramdisk about the change. – aquaherd May 19 '12 at 8:00
If you don't update the initial ramdisk with the plymouth theme, it may shutdown with your selection but with the old selection until the kernel is updated. I also made a small typo; the correct command is sudo update-initramfs -u. Another hint is to install the galternatives if you want to graphically switch between themes. – aquaherd May 22 '12 at 19:03
