Resources

KDE es una comunidad de software libre, que produce una amplia gama de aplicaciones, incluyendo el conocido entorno de escritorio Plasma.

El soporte para KDE en Gentoo es excelente, con un empaquetado completo de KDE Frameworks 5, Plasma 5 y aplicaciones de KDE 5, así como una amplia gama de programas diversos basados en KDE.

Requisitos previos

Perfil

Importante
Read relevant documentation before performing any profile changes.

La elección de un perfil adecuado, aunque no obligatorio, es recomendable pues establece una serie de parámetros USE, globales como para programas específicos, que facilitan la instalación y garantizan una experiencia de KDE sin problemas.

Con el fin de elegir el perfil más adecuado, primero liste los que están disponibles:

root #eselect profile list

  ...
  [1]   default/linux/amd64/17.1 (stable)
  [2]   default/linux/amd64/17.1/selinux (stable)
  [3]   default/linux/amd64/17.1/hardened (stable)
  [4]   default/linux/amd64/17.1/hardened/selinux (stable)
  [5]   default/linux/amd64/17.1/desktop (stable)
  [6]   default/linux/amd64/17.1/desktop/gnome (stable)
  [7]   default/linux/amd64/17.1/desktop/gnome/systemd (stable)
  [8]   default/linux/amd64/17.1/desktop/plasma (stable)
  [9]   default/linux/amd64/17.1/desktop/plasma/systemd (stable)
  ...

A continuación, seleccione el perfil adecuado, sustituyendo X con el número del perfil correspondiente:

root #eselect profile set X

Para un completo entorno de escritorio KDE, se recomienda utilizar el perfil desktop/plasma, que se adapta para su uso con OpenRC. Si se usa systemd, elija desktop/kde/systemd en su lugar. Para un entorno de escritorio Plasma 5 elija desktop/plasma con OpenRC o desktop/plasma/systemd con systemd. Nótese que otra combinación de USE puede ser técnicamente posible (especialmente si selecciona correr aplicaciones en vez de un entorno plasma completo), pero puede no ser soportado, no testeado o llevar a una inesperada perdida de funcionalidad.

Servicios

Los servicios incorporarán automáticamente las configuraciones predeterminadas, mediante los pasos de instalación de los siguientes capítulos, según la selección de perfil realizada anteriormente, pero aún es necesario configurarlos correctamente antes de iniciar KDE Plasma por primera vez. Para cambiar las configuraciones predeterminadas se recomienda hacerlo antes de instalar KDE Plasma o KDE Release Service y usar emerge ‑‑oneshot para que Portage tenga en cuenta estos cambios. Puede visitar los enlaces para obtener información sobre cómo configurar estos servicios.

Sistema de inicio

Solo debes elegir uno:

elogind: Paquete de inicio de sesión predeterminado para desktop/plasma extraído del proyecto de systemd para usarlo com OpenRC u otros sistemas de inicio.
systemd: Utiliza la parte de seguimiento de sesiones de systemd. Los usuarios de systemd no necesitan realizar ninguna otra acción adicional aquí.

Administrador de dispositivos

Solo debes elegir uno:

udev: Habilita la compatibilidad con la nomenclatura dinámica y persistente de dispositivos de udev Linux.
eudev: Bifurcación de udev para una mejor compatibilidad con kernels más antiguos y varias cadenas de herramientas.
systemd Utiliza la parte del administrador de dispositivos de systemd. Los usuarios de systemd no necesitan tomar ninguna otra iniciativa aquí.

Varios

D-Bus: Permite el uso del sistema de bus de mensajes D-Bus.
polkit: Activa el marco polkit para controlar los privilegios de los servicios de todo el sistema.
udisks: Habilita la compatibilidad con algunos servicios relacionados con el almacenamiento.

Servidor X

Lea y siga las instrucciones del artículo X server para configurar el entorno X.

Emerge

root #emerge --ask kde-plasma/plasma-meta

Puede optar por kde-plasma/plasma-desktop que proporciona un escritorio muy básico, dejando al usuario la libertad de instalar solo los paquetes adicionales que necesite, o bien, añadir las características que le hagan falta.

Advertencia
Tenga en cuenta que instalar solo kde-plasma/plasma-desktop excluirá paquetes importantes y ncesarios para que KDE Plasma funcione correctamente, como: kde-plasma/powerdevil (Gestor de energía, suspensión e hibernación), kde-plasma/systemsettings, y algunos más. Este paquete debe utilizarse teniendo en cuenta que será necesario instalar paquetes adicionales para garantizar un entorno funcional. No espere soporte cuando utilice este paquete

Iniciar Plasma

Gestor de pantallas

Display manager

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/display-manager. Also, be sure to read through the SDDM page if further issues appear.

Sin gestor de pantallas

Plasma puede iniciarse a la antigua usando startx, pero hay que tener cuidado y asegurarse que obtiene una sesion valida

ARCHIVO ~/.xinitrc

#!/bin/sh
exec dbus-launch --exit-with-session startplasma-x11

Cuando se usa Wayland, plasma puede iniciarse con dbus-launch --exit-with-session startplasma-wayland

Esto puede añadirse al archivo de configuración del usuario que se ejecutará al iniciar sesion

ARCHIVO ~/.profile

#!/bin/sh
dbus-launch --exit-with-session startplasma-wayland

Widgets

Muchos útiles widgets se encuentran en el paquete kde-plasma/kdeplasma-addons (el cuál ya es incluido en kde-plasma/plasma-meta):

root #emerge --ask kde-plasma/kdeplasma-addons

Bandeja del sistema

Plasma 5 uses the StatusNotifier specification for systray icons ^[1]. As not all applications have been ported to the new system, some workarounds exist ^[2], and Plasma 5 has a means to convert old xembed-based system tray icons to StatusNotifier icons.

Legacy support is enabled by activating legacy-systray for kde-plasma/plasma-meta, which is pulling in kde-plasma/xembed-sni-proxy.

ARCHIVO /etc/portage/package.use/kde-plasma-settingsChange USE flags for kde-plasma/plasma-meta

# xembed system tray support for legacy applications
kde-plasma/plasma-meta legacy-systray

Pidgin

net-im/pidgin requires x11-plugins/pidgin-indicator. After install, the Ubuntu Indicator plugin can be found under Tools | Plugins.

KWallet

Many users will be introduced to kde-frameworks/kwallet, Plasma's encrypted password storage, while adding a (wireless) network connection after login or adding E-Mail accounts in kde-apps/kmail.

For managing KWallets, importing and exporting passwords, there is kde-apps/kwalletmanager:

root #emerge --ask kde-apps/kwalletmanager

Desbloqueo autónomo de KWallet

kde-plasma/kwallet-pam provides a mechanism to avoid being subsequently asked for access to kwallet after login.

root #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:

ARCHIVO /etc/pam.d/sddmConfig lines for KWallet PAM unlocking via SDDM

-auth           optional        pam_kwallet5.so
-session        optional        pam_kwallet5.so auto_start

Nota
For LightDM, /etc/pam.d/lightdm needs to be edited instead.

Nota
If the filesystem containing a user's KWallet files is mounted by pam_mount upon logging on, it may be required to copy ~/.local/share/kwalletd/kdewallet.salt to the same path on the 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.

Deshabilitar KWallet

To disable the KWallet subsystem completely, edit the following file:

ARCHIVO ~/.config/kwalletrc

[Wallet]
Enabled=false

SSH/GPG Agent startup/shutdown scripts

ssh-agent scripts are located in /etc/xdg/plasma-workspace/env and /etc/xdg/plasma-workspace/shutdown. Shutdown scripts require executable bit set because they are not sourced. The Keychain article provides more information about this.

Non-root user authentication for dialogs

Some KDE dialogs such as printers, adding wireless networks and adding users require administrator authentication. This is handled through sys-auth/polkit and operates independently from app-admin/sudo. By default in Gentoo, the root account is the only administrator, and so even if a user account can run root commands through sudo, authentication in these KDE dialogs will fail.

Adding wireless networks using net-misc/networkmanager is allowed by a polkit rule which is part of the Gentoo package and already allows access for every user in the group plugdev. For other dialogs the behavior must be configured manually: If all users of the group wheel are required to be administrators, create a copy of /etc/polkit-1/rules.d/50-default.rules starting with a number lower than 50, and edit the line return ["unix-user:0"] to the following:

ARCHIVO /etc/polkit-1/rules.d/49-wheel.rulesAdministrator wheel group

polkit.addAdminRule(function(action, subject) {
    return ["unix-group:wheel"];
});

The Polkit wiki page provides more details on rules configuration.

Correr aplicaciones GUI con privilegios root

Advertencia
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. This requires Xorg, and only works within X^[3].

ARCHIVO /etc/portage/package.use/kde-plasma-settingsChange USE flags for kde-plasma/kde-cli-tools

# Build graphical frontend for kde-frameworks/kdesu (requires X)
kde-plasma/kde-cli-tools kdesu X

Remember to rebuild the package to pick up the changes:

root #emerge -1 kde-cli-tools

It can be used by invoking kdesu either from KRunner or a terminal emulator:

user $kdesu <nombre-del-programa>

A message dialog will be displayed prompting for the root password.

Nota
Some applications such as kwrite, dolphin etc. refuse to be opened with kdesu for security reasons.

Nota
{{{1}}}

Files

XDG standard directories are being used for KDE Plasma and KDE applications:

$XDG_CONFIG_HOME (defaults to $HOME/.config) - Configuration files
$XDG_DATA_HOME (defaults to $HOME/.local/share) - Application data

Removal

The first step to remove KDE Plasma and its dependencies is to unmerge kde-plasma/plasma-meta. This will not yet remove any files from the installation, so the desktop environment will keep running:

root #emerge --ask --depclean --verbose kde-plasma/plasma-meta

In a next step it makes sense to scan /etc/portage directory for any KDE Plasma specific entries in package.mask, package.unmask and package.accept_keywords and clean them up.

Finally, run the command to uninstall any Plasma packages and their dependencies. It would make sense to quit any running Plasma session beforehand:

root #emerge --ask --depclean

Advertencia
Please note that this will not just remove KDE Plasma but also any other package not registered (or being depended on) in @world. It makes sense to carefully read through the list of packages to be removed before continuing. Alternatively, run this command prior to unmerging of kde-plasma/plasma-meta to get an overview of already dangling packages on the system.

Aplicaciones

Release Service consists of various applications and supporting libraries based on Qt 5/KDE Frameworks 5.

Versiones disponibles

Instalación

The kde-apps/kde-apps-meta package provides the full Release Service bundle:

root #emerge --ask kde-apps/kde-apps-meta

If not all the packages are required, one or several smaller meta packages from the list above may be picked instead. Alternatively, it is possible to set USE flags to reduce the number of applications installed by kde-apps/kde-apps-meta.

Cambiar el idioma

Plasma-5 and Applications are shipping their localization per-package. Enable desired localization in System Settings.

KDE PIM

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

Frameworks

KDE Frameworks 5 es una colección de bibliotecas y de frameworks que proporcionan la base para KDE Plasma 5 y las aplicaciones de KDE 5, pero pueden ser utilizadas por cualquier aplicación Qt.

Como los frameworks son, en su mayoría, bibliotecas y proporcionan poca funcionalidad de usuario, ello hace que no sea necesaria su instalación de forma manual —los paquetes requeridos serán obtenidos automáticamente, así como sus dependencias—.
