This article contains a listing of known keys that can be used with Kiosk and what they do. How to actually use these keys and other capabilities of Kiosk such as URL restrictions, creating assigning profiles, etc. is covered in the Introduction to Kiosk article.
Which configuration file to put these entries in depends on whether you wish to make them global to all applications or specific to one application. To make the restrictions valid for all applications, put them in kdeglobals. To enable a restriction for a specific applications place them in the application-specific configuration, e.g. konquerorrc for Konqueror.
Application Action Restrictions
These keys disable actions that are commonly found in KDE applications.
To use these actions, create a section in
kdeglobals that looks like this:
[KDE Action Restrictions][$i] action/<key>=false
|action/file_open_recent||File||Open Recent File|
|action/view_fit_to_page||View||Fit To Page (zooming)|
|action/view_fit_to_width||View||Fit To Width (zooming)|

Locking down the entire config with [$i] will cause everything to be immutable. Locking a Containment group will render that one group of widgets to be immutable, and locking a widget itself will cause it to not be movable as well as otherwise locked.
In addition, the following resource restrictions are available:
plasma/allow_configure_when_locked (since Plasma 4.4): Whether widgets and containments can be configured when immutable / locked. The default is true as a convenience to users.
plasma/containment_actions (since KDE Frameworks 5.49): Whether or not to allow Plasma mouse actions on desktop and panels (most notably context menus, but also mouse wheel to switch virtual desktops, etc.)
plasma/plasmashell/unlockedDesktop (since Plasma 5.0): Whether to allow widgets in Plasma to be unlocked; when false, the following restrictions apply:
- Widgets cannot be unlocked
- Favorites and applications in the application launchers cannot be added, removed, rearranged, or otherwise altered (since Plasma 5.7)
- Application launchers in the task manager cannot be added or removed (since Plasma 5.8)
plasma-desktop/scripting_console (since Plasma 4.4): Whether the plasma desktop scripting console is accessible or not.
plasma-desktop/add_activities (>= 4.7.1): Whether the user may add new activities or not.
Plasma offers to download new widgets, wallpapers, scripts, and other 3rd party add-ons from the KDE Store using the KNewStuff (aka "Get Hot New Stuff") framework. The buttons are typically labeled "Get New ..." with a "star" icon. If this feature is undesirable it can be disabled using the following key:
ghns (since KDE Frameworks 5.27): Whether the Download Dialog of Get Hot New Stuff can be accessed
.desktop files can have an additional
If this field is present the
.desktop file is
only considered valid if the action(s) mentioned in this field has been
authorized. If multiple actions are listed they should be separated by
.desktop file of an application lists one
or more actions this way and the user has no authorization for even one
of these actions then the application will not appear in the KDE menu,
will not allow execution via that
.desktop file and will not be used
by KDE for opening files of associated mimetypes.
These keys disable actions that are found in the KDE file dialog. To use
them, create a section in
kdeglobals that looks
[KDE Action Restrictions][$i] action/<key>=false
|action/home||Go to home directory|
|action/up||Go to parent directory|
|action/back||Go to previous directory|
|action/forward||Go to next directory|
|action/mkdir||Create new directory|
|action/sorting menu||Sorting options|
|action/short view||Select short view|
|action/detailed view||Select detailed view|
|action/show hidden||Show/hide hidden files|
|action/separate dirs||Show/hide separate directories|
There are several keys that restrict various aspects of the KDE print dialog and printing system. To use them, create a configuration section like this:
[KDE Resource Restrictions][$i] print/<resource key>=false
Note how each of the printing keys start with
print/copies: Disables the panel that allows users to make more than one copy.
print/dialog: Disables the complete print dialog. Selecting the print option will immediately print the selected document using default settings. Make sure that a system-wide default printer has been selected. No application-specific settings are honored when this restriction is activated.
print/options: Disables the button to select additional print options.
print/properties: Disables the button to change printer properties or to add a new printer.
print/selection: Disables the options that allows selecting a
(pseudo) printer or change any of the printer properties. Make sure that
a proper default printer has been selected before disabling this option.
Disabling this option also disables
print/system: Disables the option to select the printing system backend, e.g. CUPS. It is recommended to disable this option once the correct printing system has been configured.
KDE applications can take advantage of many types of resources such as configuration data, caches, plugin registries, etc. These are loaded from both system-wide as well as from per-user locations on disk. It is possible to restrict the use of the per-user resources directories, preventing users from adding to or altering existing shared resources.
This is accomplished by creating a section like this in a configuration file:
[KDE Resource Restrictions][$i] <resource key>=false
The following resources can be used as keys and controlled in this manner:
|all||n/a||All resources listed in this table|
|autostart||share/autostart||Apps to start on login|
|data_<appname>||share/apps||Application data for the application named |
|xdgdata-apps||share/application||Application .desktop files|
|services||share/services||Protocols, plugins, kparts, control panels, etc. registry|
|servicetypes||share/servicestypes||Plugin definitions, referenced in services registry entries|
|wallpaper||share/wallpapers||Desktop wallpaper images|
In kdeglobals in the
[KDE Action Restrictions] group:
opengl_screensavers: Defines whether OpenGL screensavers are allowed to be used.
manipulatescreen_screensavers: Defines whether screensavers that manipulate an image of the screen (e.g. moving chunks of the screen around) are allowed to be used.
[ScreenSaver] AutoLogout=true AutoLogoutTimeout=600
The timeout is the time in seconds that the user must be idle for before the logout process is automatically started. Be careful with this capability as it can lead to data loss if the user has unsaved files open.
Session Capability Restrictions
These keys apply to various capabilities associated with a desktop
session and are not application specific. To use them, create a section
kdeglobals that looks like this:
[KDE Action Restrictions][$i] <key>=false
custom_config: Whether the
--config command line option should be honored. The
--config command line option can be used to circumvent locked-down
editable_desktop_icons: Defines whether icons on the desktop can be moved around. In order to prevent adding, removing, or renaming icons, you should set the desktop folder read-only. (since Plasma 5.14)
lineedit_text_completion: Defines whether input lines should have the potential to remember any previously entered data and make suggestions based on this when typing. When a single account is shared by multiple people you may wish to disable this out of privacy concerns.
lineedit_reveal_password: Defines whether password input fields may have a button that allows showing the password in plain text. (since KDE Frameworks 5.30 and/or Plasma 5.9)
action/lock_screen: Defines whether the user will be able to lock the screen.
logout: Defines whether the user will be able to logout from the Plasma session.
movable_toolbars: define whether toolbars may be moved around by the user. See also
run_command: Defines whether the "Run Command" (Alt-F2) option is available.
Note: To also disable desktop context menu run command action/run_command is required at [KDE Action Restrictions]
run_desktop_files: Defines whether users may execute desktop files that are not part of the default desktop, KDE menu, registered services and autostarting services.
- The default desktop includes the files under
.local/share/kdesktop/Desktopbut not the files under
- The KDE menu includes all files under
- Registered services includes all files under
- Autostarting services include all files under
$KDEDIR/share/autostartbut not the files under
shell_access: Whether a shell suitable for entering random commands may be
started. This also determines whether the "Run Command" option
(Alt-F2) can be used to run shell-commands and arbitrary
executables. Likewise, executables placed in the user's Autostart
folder will no longer be executed. Applications can still be
autostarted by placing
.desktop files in the
.local/share/autostart directory. See also
You probably also want to activate the following resource restrictions:
- "appdata_kdesktop" - To restrict the default desktop.
- "apps" - To restrict the KDE menu.
- "xdgdata-apps" - To restrict the KDE menu.
- "services" - To restrict registered services.
- "autostart" - To restrict autostarting services.
Otherwise users can still execute .desktop files by placing them in
skip_drm: Defines if the user may omit DRM checking. At the time of writing, this primarily applies to document formats with a DRM mechanism (e.g. PDF).
action/start_new_session: Defines whether the user may start a new session.
action/switch_user: Defines whether user switching is allowed.
Whilst telemetry is disabled by default, a user can choose to enable it inside applications.
