Tenho um laptop Dell XPS 9350 (edição Ubuntu) e estou conectando-o a um monitor externo com um adaptador Dell DA200 (USB-C para VGA + HDMI + ethernet), usando VGA. Funcionou sem problemas durante meses, mas desde hoje não é mais reconhecido.
- A tela está bem (testada com outro laptop)
- Tela não detectada nas configurações Todas > GUI de exibição na tela (costumava funcionar)
- Tela não detectada via
xrandr
- O adaptador é detectado por meio de
lsusb (veja abaixo)
- Usando o Ubuntu 16.04 atualizado, kernel 4.4.0-59
- Eu não tinha instalado novos softwares / drivers antes do problema
Eu não entendo o que possivelmente mudou para que parasse de funcionar.
Na tentativa de consertá-lo, tentei reinicializar com / sem o adaptador USB e / ou a tela conectada. Sem sucesso. Eu também tentei atualizar o kernel para 4.8.0-34, mas sem sucesso também.
Alguma ideia de como voltar a funcionar? Que outras ferramentas de diagnóstico posso usar?
Saída lsusb sem adaptador:
