Question:
I installed kubuntu-desktop just to experiment with its interface. Then I decided to remove and did the traditional apt-get purge and autoremove but it seems elements of kubuntu are still there. For example interface elements, scrollbars, bootscreen etc are still there.
Is there any method I can completely remove without installing a fresh copy of ubuntu?
Solution:1
I would recommend you to use aptitude to do this operation, this will search the packages that would remove the KDE environment and leave Ubuntu's default:
sudo apt-get install aptitude aptitude search '?and(?and(?and(?reverse-depends(kubuntu),?not(?reverse-depends(ubuntu-desktop))),?automatic), ?not(?or(?priority(required), ?priority(important))))' ubuntu-desktop+
This will search for any package that kubuntu-desktop
depends to, but doesn't depends of ubuntu-desktop
. Also, this method is a bit greedy. It will remove Qt packages, ergo mplayer2, VLC and any package that depends on Qt libraries may be deleted. Add those packages with a plus sign (+) at the end, like ubuntu-desktop package in this case. For other flavors:
Xubuntu
aptitude search '?and(?and(?and(?reverse-depends(kubuntu),?not(?reverse-depends(xubuntu-desktop))),?automatic), ?not(?or(?priority(required), ?priority(important))))' xubuntu-desktop+
Lubuntu
aptitude search '?and(?and(?and(?reverse-depends(kubuntu),?not(?reverse-depends(lubuntu-desktop))),?automatic), ?not(?or(?priority(required), ?priority(important))))' lubuntu-desktop+
Gnome
aptitude search '?and(?and(?and(?reverse-depends(kubuntu),?not(?reverse-depends(ubuntu-gnome-desktop))),?automatic), ?not(?or(?priority(required), ?priority(important))))' ubuntu-gnome-desktop+
As you can see, only replace the last packages name with the name of your preferred to leave. If you used kde-core
or other metapackages you should replace "kubuntu" with the name of the metapackage.
Making sense of aptitude search
To explain exactly which package are selected, lets explain the search command more deeply:
?and( ?and( ?and( // we're searching for packages that are ?reverse-depends(kubuntu), // reverse dependencies of kubuntu ?not(?reverse-depends(ubuntu-desktop)) // and not of ubuntu-desktop ), // that fulfills the condition above ?automatic // and is automatically installed ), ?not( // and also that are not ?or( // either required nor important ?priority(required), ?priority(important) ) ) )

Solution:3
Try installing Synaptic Package Manager from the Software Center.
Or just type in a terminal: sudo apt-get install synaptic
Once you have installed and opened the program, in the sections tab, find the KDE Desktop Environment sections and select all installed (green) selections (Ctrl+Click). Then right click, select Completely remove and apply the changes by clicking the Green check mark at the top of the window.
Solution:4
You could use apt-rdepends
to find all the packages that have been installed by (the meta package) kubuntu-desktop
and use the list as the input to apt-get purge
. Possibly purging kdelibs* should be sufficient.
Another possibility would be to remove Qt (i.e. libqt4*), since KDE ist dependent on qt it will remove all KDE packages. However, this does not work very well if other Qt applications are used on the other desktop.
However, in any case, inspect the packages that apt-get
wants to remove very carefully, since potentially the whole installation could be messed up by something like this.

As Braiams didn't work for me, i did the following:
Go to /var/log/apt and search for "kubuntu-desktop" in history.log (or any of the compressed history.log.[n].gz files) to find the exact packages installed with kubuntu-desktop and remove them.
Solution:6
This worked for me:
sudo apt-get install tasksel sudo tasksel
find Kubuntu desktop in the list and remove its selection. Read and confirm the propmts.
After this I also did
sudo apt-get autoremove
Solution:7
The answer is at : https://help.ubuntu.com/community/PureGnome and http://www.psychocats.net/ubuntu/puregnome
1) Choose the method corresponding to your ubuntu version
2) Check which programs from the KDE environment you would like to keep because you need it and a) remove it from the removal list (with dependencies) or b) leave it in the list and reinstall it later.
3) Copy/past the command The command is as stated in this webpage and depends on your version, but generally looks like :
sudo apt-get remove akonadi-backend-mysql akonadi-server akregator amarok amarok-common amarok-utils apport-kde apturl-kde ark bluedevil cdparanoia cdrdao .... and a lot of packages
The command will not remove configuration files anyway, only the programs. If you want to also remove the config files, you will add the --purge option to the command.
4)
Warning: The list of packages below is for a plain default install of Ubuntu with Kubuntu. You may want to keep some of the below packages and you should review what apt is going to remove before accepting.
These removal commands were created based on what Kubuntu, Xubuntu, etc. packages were added to a default Ubuntu installation. It's possible that the commands might remove some other packages you have since added to the default and want to keep. If that's the case, keep track of which packages those are and reinstall them. Your settings should still be there.
As always,backup your partition before modifying it.

Solution:9
the proposed solution via aptitude does not work with the default kubuntu 14.04 installation, failing with an error message that says it can not find a solution.
A simple alternative, although likely not removing 100% was to do
sudo apt-get remove plasma*
This removed kde applications like kmail, k3b, kopete, digikam,and the desktop.
