Tip : How to switch from KUbuntu to Ubuntu

After installed the new version of KUbuntu Lucid Lynx, I have changed the display manager from KDE (KUbuntu) to Gnome (Ubuntu).

This is easier than we could think.

The first thing to do is to install the Ubuntu desktop :

sudo apt-get install ubuntu-desktop

That will install the Ubuntu Display Manager. You'll be asked for the Display Manager to use, choose gdm (Gnome Display Manager).

After that, you'll have the Gnome Display Manager, but you've also all the applications of the KUbuntu Desktop distribution.

To remove them, you can use this command :

sudo apt-get remove akonadi-server akregator amarok amarok-common amarok-utils apport-kde apturl-kde ark cdrdao dolphin dragonplayer exiv2 foomatic-db-gutenprint freespacenotifier gdebi-kde gnupg-agent gtk2-engines-qtcurve gwenview hpijs-ppds ibus-qt4 icoutils ijsgutenprint install-package jockey-kde k3b k3b-data kaddressbook kamera kate kbluetooth kcalc kcm-gtk kcm-touchpad kde-window-manager kde-zeroconf kdebase-bin kdebase-data kdebase-plasma kdebase-runtime kdebase-runtime-data kdebase-workspace kdebase-workspace-bin kdebase-workspace-data kdebase-workspace-kgreet-plugins kdegraphics-strigi-plugins kdelibs-bin kdelibs5 kdelibs5-data kdemultimedia-kio-plugins kdepasswd kdepim-groupware kdepim-kresources kdepim-runtime kdepim-strigi-plugins kdepim-wizards kdepimlibs-data kdepimlibs5 kdesudo kdm kfind khelpcenter4 klipper kmag kmail kmix kmousetool knm-runtime knotes konqueror konqueror-nsplugins konqueror-plugin-searchbar konsole kontact kopete kopete-message-indicator korganizer kpackagekit kppp krdc krfb krosspython ksnapshot ksysguard ksysguardd ksystemlog ktimetracker ktorrent ktorrent-data kubuntu-debug-installer kubuntu-default-settings kubuntu-desktop kubuntu-docs kubuntu-firefox-installer kubuntu-konqueror-shortcuts kubuntu-notification-helper kvkbd kwalletmanager language-selector-qt libakonadiprivate1 libao2 libattica0 libaudio2 libboost-program-options1.40.0 libclucene0ldbl libdbusmenu-qt2 libepub0 libexiv2-6 libflac++6 libibus-qt1 libindicate-qt0 libiodbc2 libk3b6 libkcddb4 libkdcraw8 libkdecorations4 libkdepim4 libkephal4 libkexiv2-8 libkfontinst4 libkipi7 libkleo4 libkonq5 libkonq5-templates libkonqsidebarplugin4 libkopete4 libkpgp4 libkscreensaver5 libksgrd4 libksieve4 libksignalplotter4 libkwineffects1 libkworkspace4 liblastfm0 libmimelib4 libmng1 libmodplug0c2 libmpcdec3 libmsn0.3 libmysqlclient16 libokularcore1 libotr2 libpackagekit-glib2-12 libpackagekit-qt-12 libphonon4 libplasma-applet-system-monitor4 libplasma-geolocation-interface4 libplasma3 libplasmaclock4 libplasmagenericshell4 libpolkit-qt-1-0 libpoppler-qt4-3 libprocesscore4 libprocessui4 libqca2 libqca2-plugin-ossl libqimageblitz4 libqt4-assistant libqt4-dbus libqt4-designer libqt4-help libqt4-network libqt4-opengl libqt4-qt3support libqt4-script libqt4-scripttools libqt4-sql libqt4-sql-mysql libqt4-sql-sqlite libqt4-svg libqt4-test libqt4-webkit libqt4-xml libqt4-xmlpatterns libqtcore4 libqtgui4 libqtscript4-core libqtscript4-gui libqtscript4-network libqtscript4-sql libqtscript4-uitools libqtscript4-xml libsolidcontrol4 libsolidcontrolifaces4 libsoprano4 libssh-4 libstreamanalyzer0 libstreams0 libtag-extras1 libtaskmanager4 libvncserver0 libweather-ion4 libxcb-shape0 libxcb-shm0 libxcb-xv0 libxine1 libxine1-bin libxine1-console libxine1-misc-plugins libxine1-x libzip1 mysql-client-core-5.1 mysql-common mysql-server-core-5.1 network-manager-kde okular okular-extra-backends openoffice.org-kde openoffice.org-style-oxygen oxygen-cursor-theme oxygen-icon-theme oxygen-icon-theme-complete packagekit packagekit-backend-apt phonon phonon-backend-xine pinentry-gtk2 pinentry-qt4 plasma-dataengines-addons plasma-dataengines-workspace plasma-desktop plasma-scriptengine-javascript plasma-scriptengine-python plasma-widget-facebook plasma-widget-folderview plasma-widget-kimpanel plasma-widget-kimpanel-backend-ibus plasma-widget-kubuntu-feedback plasma-widget-message-indicator plasma-widget-quickaccess plasma-widgets-addons plasma-widgets-workspace plymouth-theme-kubuntu-logo polkit-kde-1 printer-applet python-kde4 python-packagekit python-qt4 python-qt4-dbus python-sip quassel quassel-data shared-desktop-ontologies software-properties-kde soprano-daemon system-config-printer-kde systemsettings ttf-dejavu ttf-dejavu-extra update-manager-kde usb-creator-kde userconfig virtuoso-nepomuk
