Release 4.0 of the KDE Desktop Environment for Linux begins the KDE 4 series. It brings you a brand new interface. New icons, new window borders, new K-menu.
No more blue! More Black. And you’ll probably think, more like Vista. But wait! Microsoft did not invent the black ice look.
If you are using Ubuntu only (and not Kubuntu), you can install the KDE Desktop Environment in Ubuntu (Gnome) by doing a:
sudo apt-get install kubuntu-desktop
This will download all the packages required and install them. It may take a while. UPDATE: See this post for more information.
Once it is installed, you will have the option of choosing KDE in your session options at log in. Once Kubuntu is installed, you can then follow the steps below to install KDE 4.0.
- Add deb http://ppa.launchpad.net/kubuntu-members-kde4/ubuntu gutsy main to your /etc/apt/sources.list.
- Open a terminal and type in:
sudo apt-get update
sudo apt-get install kde4-core
- Answer yes to the prompts and wait for the download and install to finish.
- KDE 4 applications should appear in your KDE 3 K-menu or you can run a full session by selecting “KDE 4” from your login manager.
With that said, you’ll notice that you can choose between KDE 3 or KDE 4 in your Session options from your login manager.
UPDATE (): I suggest you backup all of your KDE settings as you may overwrite/clear application-specific settings and preferences. Your Amarok library and preferences will most likely get reset. It happened to me. Look for hidden folders in your Home directory that start with .kde. Those folders should be backed up.
