Choosing an appropriate profile, 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
Then, select the right profile, substituting
X with the appropriate profile number:
eselect profile set X
For Plasma 5 desktop environment choose
desktop/plasma with OpenRC or
desktop/plasma/systemd with systemd. Note that other USE flag combinations than set by the profile may technically be possible (especially if selected applications are run instead of a full KDE Plasma desktop environment), but may be unsupported, untested, or lead to unexpected loss of functionality.
Default choices of these services will be pulled in automatically - by the installation steps in the following chapters - depending on the profile selection made earlier, but still need to be set up properly before starting KDE Plasma for the first time. For deviating from the defaults, it is recommended to install them in advance of KDE Plasma or KDE Applications via
emerge ‑‑oneshot so that Portage will take them into account. Follow the links for information how to set up these services.
Choose exactly one of:
- elogind: Standalone logind package extracted from systemd project for use with OpenRC or other init systems.
- systemd: Uses the session tracker part of systemd. Users of systemd do not need to take any other initiative here.
- consolekit: Framework for defining and tracking users, login sessions, and seats. It is currently default for the desktop/plasma profile.
Choose exactly one of:
- eudev: Gentoo's fork of udev with the goal of obtaining better compatibility. It is the default for the desktop/plasma profile.
- udev: Enables support for udev Linux dynamic and persistent device naming.
- systemd: Uses the device manager part of systemd. Users of systemd do not need to take any other initiative here.
- D-Bus: Enables use of the D-Bus message bus system.
- polkit: Enables the polkit framework for controlling privileges for system-wide services.
- udisks: Enables support for some storage related services.

KDE Plasma and Applications come with many dependencies. Some of these dependencies will predetermine package choices where otherwise there would be options to choose from.
- FFmpeg: By default, dev-qt/qtwebengine has USE
system-ffmpegenabled, making it depend on media-video/ffmpeg. Users preferring media-video/libav for the rest of their system will need to switch off that flag.
- JPEG: Since 5.11.1, dev-qt/qtwebengine depends on media-libs/libjpeg-turbo. It is Gentoo's recommended default over media-libs/jpeg anyway.
Plasma 5 is the current generation of KDE's desktop environment, based on Qt 5 and KDE Frameworks 5.

Before proceeding, make sure to choose a Plasma profile.
The kde-plasma/plasma-meta package provides the full Plasma 5 desktop, configurable by a wealth of USE flags:

emerge --ask kde-plasma/plasma-meta
Alternatively, kde-plasma/plasma-desktop provides a very basic desktop, leaving users free to install only the extra packages they require - or rather, figure out missing features on their own:
emerge --ask kde-plasma/plasma-desktop
Please note that such installations will be missing important packages such as kde-plasma/powerdevil (power management, suspend and hibernate options) and kde-plasma/systemsettings if this alternative installation is used.
By default the classic tree view of kde-plasma/systemsettings is not enabled. The following USE flag will enable it:
Recompile systemsettings with new USE flags:
emerge --ask --changed-use kde-plasma/systemsettings
emerge --ask kde-plasma/kdeplasma-addons
SDDM (Simple Desktop Display Manager) is the recommended login manager and is pulled in automatically via kde-plasma/plasma-meta by default. This is the preferred option. Alternatively, LightDM can be used and pulled in by setting USE flag
-sddm for kde-plasma/plasma-meta. Change the setting accordingly in /etc/conf.d/xdm. Also, be sure to read through the SDDM page if further issues appear.
No display manager
Plasma can be started the old-fashioned way with startx, but extra care needs to be taken to ensure it gets a valid session. The following solution is limited to ConsoleKit:
#!/bin/sh exec ck-launch-session dbus-launch --sh-syntax --exit-with-session startkde
Plasma 5 uses the StatusNotifier specification for systray icons . As not all applications have been ported to the new system, some workarounds exist , and Plasma 5 has a means to convert old xembed-based system tray icons to StatusNotifier icons.
echo "kde-plasma/plasma-meta legacy-systray" >> /etc/portage/package.use/plasma-systray
For managing KWallets, importing and exporting passwords, there is kde-apps/kwalletmanager:
emerge --ask kde-apps/kwalletmanager
kde-plasma/kwallet-pam provides a mechanism to avoid being subsequently asked for access to kwallet after login.
emerge --ask kde-plasma/kwallet-pam
It requires the following setup:
- For KWallet security, use classic blowfish encryption instead of GPG
- Choose same password for login and kwallet
- Configure a display manager with support for PAM - both x11-misc/sddm and x11-misc/lightdm fulfill that requirement:
-auth optional pam_kwallet5.so -session optional pam_kwallet5.so auto_start
For LightDM, /etc/pam.d/lightdm needs to be edited instead.
If the filesystem containing your user's KWallet files is mounted by pam_mount upon logging on, you may need to copy ~/.local/share/kwalletd/kdewallet.salt to the same path on your root filesystem. Otherwise, PAM attempts to unlock KWallet before the home directory is available and fails. The file ~/.local/share/kwalletd/kdewallet.kwl which actually contains the encrypted KWallet passwords does not need to be copied.
To disable the KWallet subsystem completely, edit the following file:
SSH/GPG Agent startup/shutdown scripts
ssh-agent scripts are located in /etc/plasma/startup and /etc/plasma/shutdown. The Keychain article provides more information about this.
Run GUI applications with root privileges
It could be a very bad idea to start GUI applications with root privileges, versus adding the regular user to the relevant group or simply just running the command unprivileged. Only use kdesu when absolutely necessary.
KDE Plasma has a utility in order to start graphical programs with root privileges. It is provided by kde-plasma/kde-cli-tools - if built with USE flag
kdesu, a graphical frontend to kde-frameworks/kdesu is installed, which can be used by invoking kdesu. This can be done either from KRunner or a terminal emulator:
A message dialog will be displayed prompting for the root password.
Some applications such as kwrite, dolphin etc. refuse to be opened with kdesu for security reasons.
Releases consist of various applications and supporting libraries based on Qt 5/KDE Frameworks 5.
|KDE Applications 18.08.3||kde-apps/kde-apps-meta-18.08.3||gentoo||Stable for amd64 and x86|

|kde-apps/kdeutils-meta||Standard desktop utilities such as a archiver, a calculator, etc.|
The kde-apps/kde-apps-meta package provides the full Applications bundle, but alternatively, one or several smaller meta packages from the list above may be picked instead:
emerge --ask kde-apps/kde-apps-meta
Plasma-5 and Applications are shipping their localization per-package. Enable your localization in systemsettings.
KDE PIM is a whole suite of applications to manage personal information including mail, calendar, contacts and more. It has several optional runtime dependencies to extend its functionality:
- Virus detection: app-antivirus/clamav
- Spam filtering: mail-filter/bogofilter or mail-filter/spamassassin
KDE Frameworks 5 is a collection of libraries and software frameworks that provide the foundation for KDE Plasma 5 and KDE Applications, 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.
|KDE Frameworks 5.52.0||kde-frameworks/*-5.52.0||gentoo||Stable for amd64 and x86, Testing for arm|
|KDE Frameworks 5.54.0||kde-frameworks/*-5.54.0||gentoo||Testing for amd64, arm and x86|
|KDE Frameworks master branch||kde-frameworks/*-9999||KDE||Live version|
