Sway/de

Sway (abgeleitet von SirCmpwns Wayland Compositor) ist Article description::ein quelloffener, der für die Kompatibilität mit dem Fenstermanager konzipiert ist.

Konfiguration
Um alle verfügbaren Konfigurationsoptionen anzuzeigen:

Dateien
Jeder Benutzer, der Sway ausführt, kann die Standardkonfigurationsdatei bearbeiten, um eine angepasste Sway-Sitzung zu starten. Gentoo speichert die Datei an ihrem Standardpfad :

Terminal-Emulator
Standardmäßig verwendet die Sway-Konfigurationsdatei den  (zu finden im Paket ). Es ist eine gute Idee, diesen Terminal-Emulator zu emergen, damit ein Terminal verfügbar ist, sobald Sway läuft:

Andere beliebte Optionen sind oder, die nativ mit Wayland funktionieren. Wenn Sie Kitty verwenden, müssen Sie, die KITTY_ENABLE_WAYLAND Umgebungsvariable auf  setzen.

Eine weitere leichtgewichtige Alternative ist, aber sie ist nicht Wayland-nativ.

Anzeigekonfiguration
Die Anzeigeoptionen können wie folgt abgefragt werden:

Die Ergebnisse wurden so gekürzt, dass sie nur gewünschte Auflösung enthalten. Die Standardpositionen sind nicht richtig konfiguriert und können durch Ändern von angepasst werden. Sobald die Datei gespeichert ist, kann die Konfiguration mit ++ neu geladen werden.

Eingabegeräte
Input devices can be queried with:

Status bar
In addition to Sway's own status bar, can be used as a highly customizable status bar for Sway:

Brightness
can be used to adjust backlights and brightness. Here is an example config:

Alternatively, can also accomplish the same brightness changes via a  compatible command:

Sound volume

Taking screenshots
To add screenshot support, use the utility (found in the  package). The abbreviation  is defined as Grab Images. This utility is tailored to the specifics of the Wayland protocol. In order to install grim, use the following command:

To add support for determining the boundaries of the selected screen area, the utility, found in the  package, is used in combination with the  utility. To install slurp, use the command:

Next, edit the configuration file to add support for keyboard shortcuts to perform a screenshot operation:

Please note that the or  +  keys combination creates a screenshot in the   buffer. This allows pasting the image directly from the clipboard, without having to save to a file on disk.

For the +  or  +  +  keyboard shortcuts, the method of automatically saving the image file in the  user directory is used.

Set a random wallpaper
A random wallpaper can be pulled from a folder and be set:

Swaylock
can be used to lock the current session.

Swayidle
runs a command after a certain idle time, typically to lock and/or power off the screen.

HiDPI
To adjust sway's rendering for HiDPI displays (4K and above), the name of the display to be adjusted must be obtained. After a sway session is running, issue the following:

The  statement in the sway configuration file will accept a   parameter to adjust the scaling of the high resolution display.

Executing sway
Some s may work but are not supported by sway. Without a display manager involved sway can be started from a tty:

Omitting the may cause.

Systems that are configured with neither systemd nor elogind will need to create a shell script (or use some other means) to set the XDG_RUNTIME_DIR variable.

The environment variable can be defined in the usual configuration files. For example, if sets the XDG_RUNTIME_DIR variable in his shell's configuration file and he has chosen that the directory will be in :

With the XDG_RUNTIME_DIR defined, sway can be launched as usual:

If issues are encountered, check Sway issues on GitHub before contacting the Sway community on IRC or opening a new Gentoo bug.

Launching Sway with TTY login
This is a simple method to start sway, this can be added to a user's shell rc file, and once logged in, a Sway session will execute.

Launching Sway from a script
This method uses a script to forcibly take over a virtual terminal and launch Sway in it. The typical use case is to launch Sway automatically on boot.

This script has a few limitations:


 * XDG_RUNTIME_DIR is expected to be defined and valid, see the section above.
 * Without the  option for openvt, sway will freeze when trying to switch to a different VT (++), whether this is a bug or not is unknown.
 * The VT is not cleared when Sway exits, clear it by calling deallocvt.
 * Similarly the TTY's owner and mode are not changed back to their default values when Sway exits.

Launching this script on boot can be done with the service:

Usage
All key combinations will be defined in the configuration file.

The key is defined as the   value by default. On most keyboards this will be the Windows key.

Movement
Sway has a -like interface. (left), (down),  (up), and  (right) can be used for movement.

See for more information.

Terminal
The default key combination to open a terminal emulator is +.

GTK theme and font
Currently setting a GTK font and theme should be done by editing sway's configuration file (see Sway's wiki as well):

If encountering problems setting the mouse cursor with certain applications (including sway), this may help:

Replace custom_cursor_theme and custom_cursor_size. Adwaita and 24 are pretty much default on all Linux distributions.

Screen sharing does not work
Make sure the package is installed. By default, it is autostarted by D-Bus but it fails to run because it needs environment variables exported by Sway, and the D-Bus session is started before Sway. To fix, update the D-Bus environment by adding the following line to the beginning of Sway's config:

Applications forget logins
Some applications (e. g. ) use a Secret-Service-Agent to save credentials for login. If applications ask for account credentials every run, an incorrectly configured Secret-Service-Agent might be the reason.

First, emerge.

Then, enable the  USE flag.

Update the system to apply the new USE flag.

To run and unlock the Agent's storage when logging into a Sway session, edit these two files.
