Xfce
Xfce ist eine leichtgewichtige Desktop-Umgebung, die dafür gebaut ist, schnell, gut aussehend, und benutzerfreundlich zu sein.
Voraussetzungen
Auswählen eines Profiles
Lesen Sie die relevante Dokumentation bevor einer Änderung des Profils.
Using the basic desktop profile will provide a good set of defaults for Xfce. Other profiles can be used, but this gives a good balance between dependencies and usability, all else aside. To select the desktop profile:
root #eselect profile set default/linux/amd64/17.1/desktopVermeidung von unnötigen Abhängigkeiten
The package app-text/poppler will be pulled in as a dependency when emerging Xfce. On desktop profiles, this package will use the qt5 USE flag by default, and so will pull in Qt dependencies that may not be needed for Xfce. One way to avoid this is to disable this USE flag for poppler:
/etc/portage/package.use/xfceAufheben des qt5 USE-Flag für pobblerapp-text/poppler -qt5
Natürlich kann -qt5 auch zu /etc/portage/make.conf hinzugefügt werden, um das Flag global zu deaktivieren, falls gewünscht.
xfce4-notifyd
Dies ist ein optionaler Schritt zur Installation von xfce-extra/xfce4-notifyd anstelle von x11-misc/notification-daemon. Überspringen Sie diesen Abschnitt, wenn die Wahl des Benachrichtigungsdämons unwichtig ist.
Emerging xfce-base/xfce4-meta will pull in the virtual/notification-daemon dependency. This virtual dependency is designed to insure that Xfce will be provided with a notification-daemon, whatever suitable software the user chooses to fulfill this role.
By default, virtual/notification-daemon will satisfy this dependency by drawing in GNOME's x11-misc/notification-daemon package. Xfce users may prefer to use xfce-extra/xfce4-notifyd, if a notification-daemon has not already been installed.
By installing xfce-extra/xfce4-notifyd before emerging Xfce, the virtual package virtual/notification-daemon will use xfce4-notifyd, and pull in no other packages. Use the --oneshot option to avoid adding xfce4-notifyd to the world file:
root #emerge --ask --oneshot xfce-extra/xfce4-notifydFahren Sie nun mit der Installation fort.

Emerge
Emergen Sie xfce-base/xfce4-meta für einen Standardsatz von Xfce-Paketen, um eine einigermaßen vollständige Desktop-Umgebung zu erhalten:
root #emerge --ask xfce-base/xfce4-meta
Das xfce-base/xfce4-meta Paket enthält die folgenden Benutzeranwendungen sowie einige Bibliotheken und Systemsoftware:
| Package | Description |
|---|---|
| x11-terms/xfce4-terminal | Terminal emulator that integrates well with Xfce, "friendlier" than the standard xterm program. |
| xfce-base/xfce4-panel | Desktop panel with application launchers, panel menus, a workspace switcher, and more. |
| xfce-base/xfce4-settings | Configuration system for the Xfce desktop environment, providing configuration dialogs and tools. |
| xfce-base/thunar | Thunar is Xfce's file manager. |
| xfce-base/xfce4-appfinder | Application finder. |
| xfce-base/thunar-volman | Manages removable media and drives. |
| xfce-base/tumbler | File previewer for Thunar. |
| xfce-base/xfce4-power-manager | An application to monitor and manage power usage (especially important for laptops). Choose maximum-performance or battery-saving modes. Adjust screen brightness and setup hibernate, suspend, and shutdown actions (i.e., when the lid is shut or buttons are pressed). Can warn when the battery reaches certain levels, or even turn off the machine. Includes panel plugins to display battery/charging status, and control brightness. |
| xfce-extra/xfce4-pulseaudio-plugin | Volume control for the panel. media-sound/volumeicon may be an option for systems without pulseaudio. |
To see everything that is installed by xfce-base/xfce4-meta, see the dependency tab for that package on packages.gentoo.org.
It is not strictly necessary to use xfce-base/xfce4-meta, Xfce can be "custom built" by installing just the desired components, but be aware that this requires some knowledge of what is needed.
Zusätzliche Software
There are a number of additional applications that are part of the Xfce project and are of note:
| Package | Description |
|---|---|
| app-cdr/xfburn | CD burning application. |
| app-editors/mousepad | Lightweight text editor. |
| x11-themes/xfwm4-themes | Several window-manager themes. |
| xfce-extra/thunar-archive-plugin | Plugin for Thunar to work with archives; uses app-arch/file-roller. |
| xfce-extra/xfce4-battery-plugin | Displays battery percentage, time remaining, power source (AC or battery), fan status, warnings, and can even be configured to execute commands at certain power levels, which can be used to put the laptop into hibernate mode when the battery is almost exhausted. |
| xfce-extra/xfce4-mount-plugin | One-click mounting of devices listed in /etc/fstab. |
| xfce-extra/xfce4-sensors-plugin | Monitor hardware sensors, such as CPU temperature, fan RPM, hard drive temp, motherboard voltage, and more. |
| xfce-extra/xfce4-verve-plugin | A small command line embedded into the panel; quicker than opening up another terminal to run a command. |
This is just a partial selection of packages available in the Gentoo repository, see xfce-extra , or use eix (eix --category xfce-extra), to see packages from the xfce-extra category. See also https://www.xfce.org/projects/ for more information.
The following applications work well in Xfce to round out a basic desktop environment:
| Package | Description |
|---|---|
| x11-misc/alacarte | GNOME's menu editor works fine in Xfce. |
| x11-terms/tilda | Lightweight quake-style terminal emulator. |
Bedienung
Xfce Starten
Xfce can either be run from a terminal after login, launched automatically after login, or be started by a graphical display manager that will greet the user and ask for login details.
Xfce ohne Display-Manager Starten
startx and startxfce4 are two of the readily available options for starting Xfce without using a display manager.
startx
When using startx, create an ~/.xinitrc file with the following contents:
~/.xinitrcStarten von xfce4 beim Aufrufen von startxexec startxfce4
If experiencing authorization or permissions issues, see the troubleshooting section.
startxfce4
To launch the Xfce4 desktop, simply type startxfce4 at the command-line and press enter:
user $startxfce4Display-Manager
It is possible to use a display manager to start Xfce. Please refer to the display manager article to configure a display manager.
Most display managers use .desktop files to configure available sessions. The following is an example desktop file that could be used to launch Xfce via a display manager:
xfce4.desktopXfce4 desktop file for display managers[Desktop Entry]
Encoding=UTF-8
Name=Xfce4
Comment=Use this session to run Xfce 4 as desktop environment
Exec=/usr/bin/startxfce4
Icon=/usr/share/pixmaps/xfce4_xicon1.png
Type=Application
The desktop file can be placed in the right location for the display manager.
Konfiguration
Xfce is a desktop environment and as such can be tuned and tailored to the needs of (almost) every user. In this section, a number of popular (or more challenging) aspects are covered.
Lautstärketasten
Install xfce-extra/xfce4-volumed-pulse to manage the volume keys:
root #emerge --ask xfce-extra/xfce4-volumed-pulsemedia-sound/tudor-volumed may be an option for systems not using pulseaudio.
Alternatively, custom keys can be bound to amixer by running xfce4-keyboard-settings:
- volume up button: amixer set Master 5%+
- volume down button: amixer set Master 5%-
- mute button: amixer set Master toggle
Konsistente GTK-3-Themen
One option is to use the Greybird theme, which has support for GTK 2, GTK 3, xfwm4, emerald, and metacity:
root #emerge --ask x11-themes/greybirdGo to Xfce menu -> Settings -> Appearance. Or run xfce4-appearance-settings. Select "Greybird" from the "Style" list.
Now GTK 2 and GTK 3 applications should have a consistent look.
GTK client side decorations
XFCE by default disables GTK client side decorations. If one wishes to enable them, they can set GTK_CSD=1 environment variable. Apps like Firefox use client side decorations to hide their own title bar.
Andere Themen
Other themes available in Portage that are compatible with XFCE can be emerged with the following list:
root #emerge --ask x11-themes/clearlooks-phenix x11-themes/gnome-themes-standard x11-themes/light-themes x11-themes/murrine-themes x11-themes/shiki-colors x11-themes/tactile3 x11-themes/zukiniFehlersuche
Enable vertical window snapping
Most modern desktop environments have vertical window snapping enabled by default. This is also possible in Xfce, but not by default. To enable, navigate to: Settings → Window manager → Advanced tab.
- Make sure the "Snap windows to screen border" checkbox has been checked.
- Make sure the checkboxes under "Wrap workspaces when reaching the screen edge" have been unchecked. These interfere with vertical window snapping.
Once the checkboxes are set it should be now possible to drag a window to the right or left side of the screen, which should cause the window to resize to 50% of the screen width.
Keyboard shortcuts can be set in order to do this via the typical Super+← or Super+→ behavior. Navigate to Settings → Window manager → Keyboard tab.
Set the "Tile window to the left" and "Tile window to the right" actions with the Super+← and Super+→ key combinations respectively.
Audio mixer complains about missing pavucontrol binary
Clicking the speaker (audio) icon in the panel and then selecting Audio mixer... results in a message saying "pavucontrol binary not found".
The solution is to install media-sound/pavucontrol:
root #emerge --ask media-sound/pavucontrolXfce4-Bildschirmschoner lässt sich nicht entsperren
Xfce-screensaver uses gnome-keyring by default to authenticate. By applying the installation method above, gnome-keyring will not be pulled and pam will be unable to service the default configuration installed in /etc/pam.d/xfce4-screensaver. Either pull gnome-keyring, otherwise the file should be modified to allow system-auth to be used on passwords:
/etc/pam.d/xfce4-screensaverauth include system-auth
password include system-auth
Authorization or permissions issues
When experiencing authorization or permissions issues within xfce4 in an OpenRC profile (symptoms include being unable to open power manager and unable to suspend/hibernate) make sure that sys-auth/elogind is installed and properly configured, and that the elogind USE flag is globally enabled.
If launching with startx, replace the appropriate line in ~/.xinitrc with the following:
~/.xinitrcStarting xfce4 the right way when invoking startxexec dbus-launch --exit-with-session xfce4-session
Dual-monitors get mirrored after monitor suspend
There are (at least) three ways to solve this issue. First is to save the display settings as the default monitor layout profile, then enable that profile as "new monitors connect". There's also the option to show a dialog whenever new monitors are detected, which will default to the profile instead of mirroring, when one is available. Navigate to Settings -> Display -> Advanced to find these options. Remember to configure the display settings before saving the first profile.
2nd way is to kill xfsettingsd after logging to the Xfce session. However this will also make some functionality unavailable, such as global hotkeys. A custom script can be created that kills the service, and add that to the autostarting applications list.
3rd is to have a custom script that can be executed via a .desktop icon on the desktop, panel, or ran manually each time the monitors are turned on.
Review the monitor IDs using the xrandr command.
The custom script could look something like the following:
~/bin/configuremonitors.shconfiguremonitors.shxrandr --output HDMI-A-0 --right-of DisplayPort-0 --auto
