== Plasma ==
To benefit from Plasma's UI for managing Thunderbolt devices, you may install the System Settings panel. Just add this to your packages: <code>plasma5Packages.plasma-thunderbolt</code>.

== Enable the Bolt daemon ==

Even if you don't use Gnome, you may want to enable the Bolt daemon - just configure the following:

<syntaxhighlight lang="nix">services.hardware.bolt.enable = true;</syntaxhighlight>

This will enable the bolt daemon on your system.

For the description of this option, cf. https://search.nixos.org/options?channel=21.11&from=0&size=50&sort=relevance&type=packages&query=services.hardware.bolt.enable.

== Enroll Thunderbolt devices ==

If your Thunderbolt device does not work, execute <code>boltctl</code> in a terminal. This will show you your connected devices, and their respective uuid. In color terminals, it will show you if your device is authorized (green light) or not (orange light).

'''For each device''' that is not authorized, execute <code>boltctl enroll --chain UUID_FROM_YOUR_DEVICE</code>.
{{Note|You'll have to replace <code>UUID_FROM_YOUR_DEVICE</code> with your device's actual uuid}}.

Check with <code>boltctl</code> whether all your devices have been enrolled (green light everywhere).

== Dell's TB16 dock ==
On a Dell XPS 13" 9360, the TB16 is not always authorised automatically, and you may have the impression that it does not work correctly (connected USB devices won't work while the DisplayPort may work...).

When connecting a TB16, <code>boltctl</code> shows 2 devices: ''Dell Thunderbolt Dock'' and ''Dell Thunderbolt Cable''.

It is enough to enroll the ''Dell Thunderbolt Dock'' with the <code>--chain</code> parameter, as this will also automatically enroll the ''Dell Thunderbolt Cable''.
