Eu tenho um conector usb-c que eu gostaria de usar um monitor externo, mouse e teclado todos conectados a uma única porta usb-c através de um dynadock toshiba. Ao adicionar o Ubuntu 17.1 como um sistema de inicialização dupla com as janelas originais (nas quais todas essas coisas funcionaram bem), parece que perdi parte do suporte a usb-c - o monitor e o mouse USB não funcionam, embora o teclado ainda funcione. Se eu mudar para outro conector usb, o mouse ganha vida, mas ainda não há monitor.

que é principalmente grega para mim mas parece mostrar algum problema com um 'pintor de evdi'. Isusb mostra:

Essa tela wayland não se parece com o monitor externo, a julgar pelas dimensões físicas (a tela é algo como 22 "x 12" ou cerca de 50cm x 30cm) O painel de controle do monitor não detecta o monitor externo. Então, quaisquer dicas apreciadas - tia, jr
