I wanted to try out different desktop environments so I installed XFCE, KDE, GNOME, etc on top of Unity in Ubuntu 12.04
After a while I decided that I didn't like those other DEs and would stick to Unity.
So I changed my default DE to Unity by configuring gdm
.
sudo dpkg-reconfigure gdm
Now I am able to choose my DE at login time and all of DEs are working properly.
But the strange thing is that my boot up screen says 'lubuntu', my login screen is KDE, and my desktop is Unity.
How and why is this happening? Why didn't my gdm configuration have any effect? Does login and boot up screen need to be configured separately from the DE?
There are other similar questions here but they are not the same as this one. I do not want to remove the other enviroments I'm quite happy with having a list of DEs to select from. I want to know how to set proper defaults.

You can remove the Lubuntu splash screen in several ways. If you want to change splash screens every once in a while you can run:
You will be presented with a screen like the following:
In this case, entering a 0 or a 1 will set the splash screen to the Kubuntu logo, while entering 2 will set it to the default Ubuntu logo.
If you want to get rid of the Lubuntu logo permanently, you can remove the package using:
Replacing
lubuntu
with the desktop environment you installed.You might be asked to remove
lubuntu-desktop
that's OK, as its a meta package.If you've configured
gdm
usingsudo dpkg-reconfigure gdm
you shouldn't have a KDE (KDM) login screen. If your login screen looks something like this:Then try configuring
gdm
again. If that doesn't work you can removekdm
with:Again, you might be asked to remove
kubuntu-desktop
. Its also a meta package, so go ahead and remove it.
