Apple Thunderbolt Display sur Ubuntu 18.04.1

Question

Exécution du dernier LTS Ubuntu sur un nouveau Intel NUC

J'essaie de faire fonctionner mon écran Apple Thunderbolt. Puisque le NUC a TB3, j'ai acheté un adaptateur TB3 vers TB2 . L'écran ne s'allume pas, pas plus que tout ce qui est connecté à l'un des ports de l'écran.

Lorsque je connecte un disque dur externe Firewire via un dongle Apple Thunderbolt à Firewire, Ubuntu reconnaît et installe le lecteur.

dmesg montre quelque chose d'intéressant:

Les lignes topology limit exceeded semblent troublantes, mais il y a certainement autres sur les forums qui semblent avoir fait fonctionner cet affichage.

Des idées ce que je fais mal ici?

Answer 1

Essayez de modifier les paramètres Thunderbolt dans le BIOS, réglez Thunderbolt sur Assistant BIOS au lieu du mode natif.
