Disallow the user to enable or disable GNOME Shell extensions.

# Lock down enabled extensions

In GNOME Shell, you can prevent the user from enabling or disabling extensions by locking down the `org.gnome.shell.enabled-extensions` and `org.gnome.shell.development-tools` keys. This allows you to provide a set of extensions that the user has to use.

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.

# Lock down the org.gnome.shell.enabled-extensions and org.gnome.shell.development-tools keys

Create a `user` profile in /etc/dconf/profile/user:

user-db:user system-db:local

Create a `local` database for machine-wide settings in /etc/dconf/db/local.d/00-extensions:

[org/gnome/shell] # List all extensions that you want to have enabled for all users enabled-extensions=['myextension1@myname.example.com', 'myextension2@myname.example.com'] # Disable access to Looking Glass development-tools=false

The `enabled-extensions` key specifies the enabled extensions using the extensions’ uuid (`myextension1@myname.example.com` and `myextension2@myname.example.com`).

The `development-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:

# Lock the list of enabled extensions /org/gnome/shell/enabled-extensions /org/gnome/shell/disabled-extensions /org/gnome/shell/development-tools

After locking down the `org.gnome.shell.enabled-extensions` and `org.gnome.shell.development-tools` keys, any extensions installed in ~/.local/share/gnome-shell/extensions or /usr/share/gnome-shell/extensions that are not listed in the `org.gnome.shell.enabled-extensions` key will not be loaded by GNOME Shell, thus preventing the user from using them.
