Ubuntu 22.04 displayport 切入切出

  • 772

我有 Ubuntu 22.04 和 NVIDIA Corporation GA102 GeForce RTX 3080 显卡。显卡有 3 个 Displayport 输出和 1 个 HDMI。我有一个插入 HDMI 的华硕 VE278 显示器，它工作正常。HDMI 插入一根 HDMI 线从计算机连接到 KVM，另一根 HDMI 线从 KVM 连接到 ASUS VE278。

我还有一个插入了 Displayport 的 ASUS VE276。它有一条 Displayport 电缆直接从计算机连接到 VE276。

计算机启动时，两个屏幕都显示 POST、Ubuntu 加载徽标、登录屏幕等。

但是，当它最终加载到 KDE 中时，Displayport 显示器变黑并且我在屏幕上看到“DisplayPort 无信号”。

我正在使用 Nvidia 视频驱动程序：

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

当前发现的监视器：

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

更多信息：

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

为什么它会在一切都在启动时看到 DisplayPort 监视器，然后在 KDE 最终加载时却找不到它？

    我注意到当我运行这个命令（DP-4）时显示器确实出现了：

    $ xrandr --verbose
