Eu tenho um problema muito irritante após uma instalação limpa do Ubuntu 18.04.
Configuração
Um monitor de 24 "conectado a um laptop Dell XPS 13 (9365 2 em 1) por meio de um dock Dell conectado à porta ThunderBolt. No dock, uso uma porta de mini-display para exibir a porta para conectar o dock ao monitor .
Problema
Quando ligo o laptop, o monitor funciona e vejo as informações de inicialização (BIOS) e a solicitação de senha da unidade criptografada. Quando a tela de login (gnome) está prestes a ser exibida, o monitor desliga e não se recupera desse estado. Eu tenho que desconectar o laptop da estação de acoplamento, fazer login e reconectar a estação / monitor. Às vezes, as duas telas estão roxas, o ponteiro do mouse se move na tela, mas nada mais acontece.
