Displayport do Ubuntu 22.04 cortando e saindo

  • 772

Eu tenho o Ubuntu 22.04 e uma placa de vídeo NVIDIA Corporation GA102 GeForce RTX 3080. A placa de vídeo tem 3 saídas Displayport e 1 HDMI. Eu tenho um monitor ASUS VE278 que tem o HDMI conectado e funciona bem. O HDMI está conectado com um cabo HDMI que vai do computador para um KVM e outro cabo HDMI do KVM para o ASUS VE278.

Eu também tenho um ASUS VE276 que tem o Displayport conectado. Este tem um cabo Displayport indo direto do computador para o VE276.

Quando o computador está inicializando, ambas as telas mostram o POST, o logotipo de carregamento do Ubuntu, as telas de login, etc.

No entanto, quando ele finalmente carrega no KDE, o monitor Displayport fica preto e eu recebo "DisplayPort No Signal" na tela.

Estou usando o driver de vídeo da Nvidia:

lspci | grep VGA
01:00.0 VGA compatible controller: NVIDIA Corporation GA102 [GeForce RTX 3080 12GB] (rev a1)

monitores atualmente encontrados:

xrandr --listmonitors
Monitors: 1
 0: +*HDMI-0 1920/598x1080/336+0+0  HDMI-0

Mais informações:

lspci -k | grep -EA3 'VGA|3D|Display'
01:00.0 VGA compatible controller: NVIDIA Corporation GA102 [GeForce RTX 3080 12GB] (rev a1)
        Subsystem: Micro-Star International Co., Ltd. [MSI] Device 389b
        Kernel driver in use: nvidia
        Kernel modules: nvidiafb, nouveau, nvidia_drm, nvidia

Por que ele veria o monitor DisplayPort enquanto tudo estava inicializando e não seria capaz de encontrá-lo quando o KDE finalmente carregasse?

    Percebi que o monitor apareceu quando executei este comando (DP-4):

    $ xrandr --verbose
