Eéntoepassingsmodus configureren

Eéntoepassingsmodus is een aangepaste Gnome Shell waarin de Shell als interactieve kiosk ingesteld is. De beheerder vergrendelt sommige functies om de standaardbureaubladomgeving voor gebruikers meer te beperken, waardoor ze zich beter op specifieke functies kunnen focussen.

Set up single-application mode for a wide range of functions in a number of fields (from communication to entertainment or education), and use it as a self-serve machine, event manager, registration point, and so on.

Your distribution might provide the GNOME Kiosk session, which is usually available in the gnome-kiosk package. You can use it to configure single-application mode more easily. Otherwise, use the following procedure.

Eéntoepassingsmodus instellen

  1. Vergrendel de instellingen om afdrukken, terminaltoegang, enz. te verhinderen.

  2. Configure automatic login in the /etc/gdm/custom.conf file for the user.

  3. Create the following files with the listed content:

    /usr/share/applications/org.gnome.Kiosk.Script.desktop 
    [Desktop Entry]
Name=Kiosk
Type=Application
Exec=gnome-kiosk
    /usr/share/applications/org.gnome.Kiosk.WindowManager.desktop 
    [Desktop Entry]
Type=Application
Name=Mutter
Comment=Window manager
Exec=/usr/bin/mutter
Categories=GNOME;GTK;Core;
OnlyShowIn=GNOME;
NoDisplay=true
X-GNOME-Autostart-Phase=DisplayServer
X-GNOME-Provides=windowmanager;
X-GNOME-Autostart-Notify=true
X-GNOME-AutoRestart=false
X-GNOME-HiddenUnderSystemd=true
    /usr/share/gnome-session/sessions/gnome-kiosk.session 
    [GNOME Session]
Name=Kiosk
RequiredComponents=org.gnome.Kiosk.WindowManager;org.gnome.Kiosk.Script;
    /usr/share/X11/xorg.conf.d/20-gnome-kiosk.conf 
    Section "ServerFlags"
    Option "DontVTSwitch" "on"
EndSection
    /usr/share/xsessions/org.gnome.Kiosk.desktop 
    [Desktop Entry]
Name=Kiosk
Comment=Kiosk mode
Exec=/usr/bin/gnome-session --session=gnome-kiosk
DesktopNames=GNOME-Kiosk;GNOME;

  4. As the user that will open the single-application session, create the /home/user/.local/bin/gnome-kiosk file:

    [user]$ mkdir -p ~/.local/bin

[user]$ touch ~/.local/bin/gnome-kiosk

  5. Edit the /home/user/.local/bin/gnome-kiosk file and enter the executable name of the application that you want to launch in single-application mode.

    For example, to launch the Firefox browser in single-application mode, enter the following content:

    #!/bin/sh

while true; do
    firefox --kiosk https://example.org
done

    The while true loop ensures that the application restarts if it terminates for any reason.

  6. Make the file executable:

    [user]$ chmod +x ~/.local/bin/gnome-kiosk

  7. If you created the file or its containing directories as a different user than the single-application user, such as root, ensure that the file has the correct permissions:

    # chown -R user:group ~user/.local

  8. At the GNOME login screen, select the Kiosk session from the gear button menu and log in as the single-application user.
