KDE is a free software community, producing a wide range of applications including the popular Plasma desktop environment.
Gentoo support for KDE is excellent, with comprehensive packaging of the legacy KDE SC 4, next generation KDE Frameworks, Plasma, and Applications 5, as well as a wide array of other miscellaneous KDE-based software.

Choosing a KDE desktop profile in case of KDE SC 4 or a Plasma desktop profile in case of Plasma 5, although not required, is recommended as it sets a number of global and package-specific USE flags to ease installation and ensure a smooth KDE experience.
In order to choose the most suitable profile, first list what's available:
eselect profile list
 default/linux/amd64/13.0  default/linux/amd64/13.0/selinux  default/linux/amd64/13.0/desktop  default/linux/amd64/13.0/desktop/gnome  default/linux/amd64/13.0/desktop/gnome/systemd  default/linux/amd64/13.0/desktop/kde  default/linux/amd64/13.0/desktop/kde/systemd  default/linux/amd64/13.0/desktop/plasma  default/linux/amd64/13.0/desktop/plasma/systemd ...
Then, select the right profile, substituting
X with the appropriate profile number:
eselect profile set X
For a full KDE desktop environment it is recommended to use the
desktop/kde profile, which is tailored for use with OpenRC. If systemd is used, choose
desktop/kde/systemd instead. For Plasma 5 desktop environment choose
desktop/plasma with OpenRC or
desktop/plasma/systemd with systemd.
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 are run instead of a full KDE desktop environment), but may be unsupported, untested, or lead to unexpected loss of functionality.
Read and follow the instructions in the X server article to setup the X environment.
KDE SC 4
KDE SC 4 is the previous major version of KDE. There is no more feature development, but it is still supported by upstream with bugfix releases. It is considered stable, and is recommended for most users.
|KDE SC version||Status|
|KDE SC 4.14.3||Stable for amd64, ppc, ppc64 and x86; testing for arm|
As upstream support for KDE SC 4 slowly comes to an end, certain packages have releases with versions that do not not match the rest of the SC. For example, kdelibs enjoys further point releases beyond the last 4.14.3 SC release, and KDE Workspaces continues to receive bugfix releases as 4.11.x.
In Gentoo there are various packages that will install a KDE environment:
- kde-base/kde-meta, the full KDE suite
- kde-apps/kdebase-meta, a basic KDE environment
- kde-base/kdebase-startkde, a very minimal, effectively unsupported KDE environment (no KDE applications or artwork)
It is usually a good idea to start with the kde-apps/kdebase-meta package and install the additional software when needed:
emerge --ask kde-apps/kdebase-meta
There are other meta packages that can be installed to pull in parts of the KDE suite:
- kde-apps/kdeaccessibility-meta: Accessibility applications and utilities.
- kde-apps/kdeadmin-meta: Administrative utilities, which helps in managing the system.
- kde-apps/kdeartwork-meta: Extra themes, screensavers, etc.
- kde-base/kdebindings-meta: Bindings for various languages.
- kde-apps/kdeedu-meta: Educational applications and games.
- kde-apps/kdegames-meta: Standard desktop games.
- kde-apps/kdegraphics-meta: Graphics applications such as image viewers, color pickers, etc.
- kde-apps/kdemultimedia-meta: Audio and video playback applications and services.
- kde-apps/kdenetwork-meta: Network applications and VNC services.
- kde-base/kdepim-meta: PIM applications such as emailer, addressbook, organizer, etc.
- kde-apps/kdesdk-meta: Various development tools.
- kde-apps/kdetoys-meta: Toy like applications.
- kde-apps/kdeutils-meta: Standard desktop utilities such as a archiver, a calculator, etc.
- kde-apps/kdewebdev-meta: Web development tools.
E.g. to use the German language, set:
emerge --ask kde-base/kde4-l10n
KDM (KDE Display Manager) is the recommended login manager and is pulled in automatically via kde-base/kdebase-meta.
Set KDM as the default display manager:
To start KDM on boot, add xdm to the default runlevel:
rc-update add xdm default
To start KDM now:
Enable KDM at boot time through systemctl:
systemctl enable kdm
Now start the service:
systemctl start kdm
KDE Frameworks, Plasma, and Applications 5
The next generation of KDE splits the SC into three components, each with their own individual release cycles: KDE Frameworks 5, KDE Plasma 5, and KDE Applications.
|KDE component & version||Gentoo package & version||Repository||Status|
|KDE Frameworks 5.11.0||kde-frameworks/*-5.11.0||gentoo||Testing for amd64 and x86|
|KDE Frameworks master branch||kde-frameworks/*-9999||kde overlay||Live version|
|KDE Plasma 5.3.1||kde-plasma/*-5.3.1||gentoo||Testing for amd64|
|KDE Plasma 5.3.2||kde-plasma/*-5.3.2||gentoo||Testing for amd64|
|KDE Plasma master branch||kde-plasma/*-9999||kde overlay||Live version|
|KDE Applications 15.04.2||kde-apps/kde-apps-meta-15.04.2||kde overlay||Masked for amd64|
|KDE Applications master branch||kde-apps/kde-apps-meta-9999||kde overlay||Masked for amd64|
KDE Frameworks 5 is a collection of libraries and software frameworks that provide the foundation for KDE Plasma 5 and KDE Applications 5, but may be leveraged by any Qt application.
As Frameworks are mostly libraries and provide little user functionality, it's not necessary to install them manually - the required packages will be pulled in automatically as dependencies.
Plasma 5 is the next generation of KDE's desktop environment, based on Qt 5 and KDE Frameworks 5. Upgrading is fairly simple, although it cannot be coinstalled with Plasma 4 due to upstream design decisions.
Note that while Plasma 5 is in a good state, it is still under heavy upstream development and is missing some features present in KDE 4.
Installation information can be found on the upgrade page.
Many useful widget are in the kde-base/kdeplasma-addons package. For KDE4, use:
emerge --ask kde-base/kdeplasma-addons
For Plasma 5, you may want to use:
emerge --ask kde-plasma/kdeplasma-addons
