11.4. Setting Up Mandatory Extensions
In GNOME Shell, you can provide a set of extensions that the user has to use. To do so, install the extensions in the
/usr/share/gnome-shell/extensions
directory and then lock down the org.gnome.shell.enabled-extensions
and org.gnome.shell.development-tools
keys.
Locking down the
org.gnome.shell.development-tools
key ensures that the user cannot use GNOME Shell's integrated debugger and inspector tool (Looking Glass) to disable any mandatory extensions.
Procedure 11.4. Setting up mandatory extensions
- Create a
local
database file for machine-wide settings in/etc/dconf/db/local.d/00-extensions-mandatory
:[org/gnome/shell] # List all mandatory extensions enabled-extensions=['myextension1@myname.example.com', 'myextension2@myname.example.com'] # Disable access to Looking Glass development-tools=false
Theenabled-extensions
key specifies the enabled extensions using the extensions' uuid (myextension1@myname.example.com and myextension2@myname.example.com).Thedevelopment-tools
key is set to false to disable access to Looking Glass. - Override the user's setting and prevent the user from changing it in
/etc/dconf/db/local.d/locks/extensions-mandatory
:# Lock the list of mandatory extensions and access to Looking Glass /org/gnome/shell/enabled-extensions /org/gnome/shell/development-tools
- Update the system databases:
#
dconf update
- Users must log out and back in again before the system-wide settings take effect.
