These instructions are for Ubuntu 12.04 running the Unity desktop on which the Lubuntu Core Desktop was installed using either the Ubuntu Software Center or
sudo apt-get on the command line.
The instructions may be the same for other versions of Ubuntu, but no guarantee is made.
When the Xubuntu Core Desktop is installed in Ubuntu 12.04, it installs several packages and libraries it requires as well as some optional packages. Not all these packages and libraries are uninstalled when you uninstall Xubuntu Core Desktop. Several packages (like
thunar) do not get uninstalled.
This is not recommended because it will remove all packages normally installed with Xubuntu Core Desktop. This may include packages you previously installed (such as
thunar) or that were installed as dependencies for other packages.
Note: this uninstall command assumes Xubuntu Core Desktop was installed on a fresh Ubuntu 12.04.
1) Open a terminal (instructions can be found here).
2) Enter the following command (it is very long and a single line):
sudo apt-get remove --auto-remove --purge desktop-base exo-utils fonts-droid gtk2-engines-xfce libexo-1-0 libexo-common libexo-helpers libgarcon-1-0 libgarcon-common libglade2-0 libjpeg-progs libjpeg-turbo-progs libkeybinder0 libthunarx-2-0 libtumbler-1-0 liburi-perl libxfce4ui-1-0 libxfce4util-bin libxfce4util-common libxfce4util4 libxfconf-0-2 lightdm-gtk-greeter miscfiles orage plymouth-theme-xubuntu-logo plymouth-theme-xubuntu-text shimmer-themes tango-icon-theme thunar thunar-data thunar-volman ttf-droid tumbler tumbler-common xfce-keyboard-shortcuts xfce4 xfce4-appfinder xfce4-mixer xfce4-notifyd xfce4-panel xfce4-session xfce4-settings xfce4-utils xfce4-volumed xfconf xfdesktop4 xfdesktop4-data xfwm4 xscreensaver xscreensaver-data xubuntu-artwork xubuntu-default-settings xubuntu-icon-theme xubuntu-wallpapers
It is easiest to copy the line and paste it into the terminal (right-click on the terminal and select Paste from the popup menu).
The better way to uninstall it is to follow the directions on this page.
This will show you on how to uninstall only the packages that were installed when Xubuntu Core Desktop was installed. The instructions are generic and work for any installed package.
- identifying which packages were installed and
- creating a command to uninstall only those packages
It leaves intact any packages you may have installed (like
thunar) or that were installed as dependencies for other programs instead of blindly assuming that they were installed along with Xubuntu Core Desktop.
Note: if Xubuntu Core Desktop was installed using the Ubuntu Software Center then there will be 3 separate installation entries you will need to find (since it was a 3 step process).
