KDE is a powerful graphical desktop environment for Unix workstations.

Available versions

KDE SC 4 is the current KDE version supported by upstream. In Portage there is a stable version, and there might be one (or more) non-stable versions. Under normal conditions new versions get in stabilized after a month. In addition, KDE upstream provides live git source repositories. The Gentoo KDE team provides git master and latest branch live ebuilds through the kde overlay.

Choose what KDE SC version is most appropriate:


KDE SC version Gentoo version Repository Status
KDE SC 4.12.5 4.12.5 Portage Stable for amd64, ppc, ppc64 and x86; testing for arm
KDE SC 4.13.3 4.13.3 Portage Testing for amd64, arm, ppc, ppc64 and x86
KDE SC 4.14 stable branch 4.14.49.9999 kde overlay Live version
KDE SC 4.x master 4.9999 kde overlay Live version


Note
Users with stable systems need to put this keywords file in /etc/portage/package.keywords to install testing versions.
Note
When KDE PIM is installed and needs to upgrade from 4.4 to 4.13, please have a look at the KDE PIM 4.7 Upgrade Guide first (it still applies)! To stick with KDE PIM 4.4 it is possible to mask KDE PIM 4.13.

Prerequisites

Profile

The Desktop profile has been split to KDE and GNOME subprofiles. This means that KDE and GNOME specific USE flags have been stripped from the basic desktop profile and have been migrated to the subprofiles. Choosing a subprofile does not restrict the system to using only the equivalent desktop environment. In order to choose the most suitable profile, run the following command to list the available profiles:

root # eselect profile list

Then, select the right profile with the following command, substituting X with the appropriate number of the profile:

root # eselect profile set X

See the page on profiles for more details.

For a full KDE desktop environment it is recommended to use the desktop/kde profile, which is specially tailored for KDE with OpenRC. If KDE with systemd is to be used, it is recommended to use the desktop/kde/systemd profile, which is specially tailored for KDE with systemd.

Services

Before installing KDE SC it is recommended that several other services are set up first. Part of that is done automatically if a desktop/kde or desktop profile is used. These services are:

  • D-Bus: Enables use of the D-Bus message bus system.
  • polkit: Enables the polkit framework for controlling privileges for system-wide services.
  • udev: Enables support for udev Linux dynamic and persistent device naming.
  • udisks: Enables support for some storage related services.

Follow the links for information how to set up these services. Note that other USE flag combinations than set in this profile may technically be possible (especially if selected applications re ran instead of a full KDE desktop environment), but may be unsupported, untested, or lead to unexpected loss of functionality.

X server

Read and follow the instructions in the X server article to setup the X environment.

Installation

Note
For update instructions, check the upgrade subpage.
Note
For live versions see the kde overlay article.

Packages

In Gentoo there are various packages that will install a KDE environment:

It's usually a good idea to start with kdebase-meta and install the additional software when needed:

root # emerge --ask kdebase-meta

There are other meta packages that can be installed to pull in parts of the KDE suite:

Localization

To localize the KDE installation, install the kde-base/kde-l10n package. If only a selected few languages needs to be used, define the LINGUAS USE flag beforehand, e.g. for German:

File/etc/portage/make.confSetting the LINGUAS variable for the German language

LINGUAS="de"
root # emerge --ask kde-l10n

To localize the packages included in kde-base/kdepim-meta install the kde-base/kdepim-l10n package.

app-office/calligra has its own localization package too: app-office/calligra-l10n.

Configuration

Boot service

KDM (KDE Display Manager) is the recommended login manager for KDE.

OpenRC

Set KDM as the default display manager:

File/etc/conf.d/xdmSetting kdm as the default display manager

DISPLAYMANAGER="kdm"

To start KDM on boot, add xdm to the default runlevel:

root # rc-update add xdm default

To start KDM now:

root # /etc/init.d/xdm start

Systemd

Enable KDM at boot time through systemctl enable:

root # systemctl enable kdm

Now run the following command to start the service:

root # systemctl start kdm

Add-on Software

Widgets

Many useful widget are in the kde-base/kdeplasma-addons package:

root # emerge --ask kdeplasma-addons

More KDE software

The most important KDE applications are in the portage tree and many are located in the kde-base and kde-misc categories.
