Ho un problema davvero fastidioso dopo un'installazione pulita di Ubuntu 18.04.
Impostare
Un monitor da 24 "collegato a un laptop Dell XPS 13 (9365 2-in-1) tramite un dock Dell collegato alla porta ThunderBolt. Dal dock utilizzo una porta mini display per visualizzare la porta per collegare il dock al monitor .
Problema
Quando accendo il laptop, il monitor funziona e posso vedere le informazioni di avvio (BIOS) e la richiesta della password per l'unità crittografata. Quando la schermata di login (gnome) sta per essere visualizzata, il monitor si spegne e non si ripristina da quello stato. Devo disconnettere il laptop dal dock, accedere, quindi ricollegare il dock / monitor. A volte entrambi gli schermi sono viola, il puntatore del mouse si sposta sullo schermo ma non succede nient'altro.
