O monitor LG é detectado mas não funciona

1

Acabei de comprar um novo monitor LG para usar como segundo monitor com meu laptop HP (Intel Integrated graphics) executando o Ubuntu. No meu Settings > Display , posso ver meu monitor detectado na GUI, mas no próprio monitor ele diz check your HDMI connection .

Pesquisei bastante e descobri que a LG tem o software Dual Monitor, mas não é fornecido para o Ubuntu. Tentei usar a ferramenta xrandr , mas isso não ajudou.

Até agora, no meu outro laptop com Ubuntu e porta VGA está funcionando lá, então o problema é com o meu driver HDMI . Eu procurei por drivers da Intel sobre isso, mas não sei se isso vai resolver o meu problema ou não.

xrandr --verbose

Eu queria instalar um segundo monitor na minha área de trabalho via HDMI. No processo de inicialização, a porta HDMI morreu. Eu consertei isso desativando o driver de exibição Nouveau do servidor X.Org X e para instalar e selecionar o driver binário NVIDIA 340.96 no Ubuntu Software & amp; Atualizações - > Menu de drivers extras.

Agora eu tenho uma configuração de tela dupla.
