I'm using Ubuntu and I would like to experience KDE desktop environment. I have installed KDE in full mode using apt-get install with no error but no further effects occurred. I don't know how to use my installation, start in KDE mode and switch between unity and KDE.

Installing KDE

To install KDE (which it sounds like you may have already done), you install one of the following packages:

  • kde-plasma-desktop

    This will only install a minimal core of KDE apps and utilities. Good if you want to use KDE but don't need all the applications and utilities that come with it.

  • kde-full

    This will install a more full range of KDE applications and utilities.

    If you have other desktop environments installed this will cause you to double-up on a fair few apps (ie, have both the Gnome and KDE equivalent installed). This is not necessarily a bad thing as it gives choice and lets you (if you want) use anything a native KDE user would use.

  • kubuntu-desktop

    This installs the full Kubuntu desktop which includes the full KDE suite, plus all of Ubuntu's "Kubuntu" look and feel, including the splash screens and greeters. It also installs additional applications that Kubuntu normally installs, like Kontact and Konversation.

    This is not usually recommended if you also have other desktop environments installed, because it changes the splash screen and greeter to Kubuntu.

Selecting KDE when logging in

  • Before you enter your password upon log-in, you need to open up the drop-down that says "Ubuntu" (which will make you use Gnome/Compiz/Unity, Ubuntu's default) and change it to KDE.

  • I installed kde-plasma-dektop and now it works well, But I'm still confused with the behavior after the previous installation. I wonder if I can find the previous installed files somewhere and add it to the list. – Ali Honarmand Feb 27 '13 at 9:26
