我有两块 Nvidia 显卡（一块板载显卡和一块外加显卡），每块显卡都连接着一台显示器。显示器处于“打开”状态，至少 LED 指示灯显示它们处于打开状态。但只有板载显卡连接的那块显示器显示我的桌面。我无法将窗口移到另一块显卡上，但光标可以显示（但发生了变化，变成了黑色十字）。
我的 xorg.conf 如下：

答案1
使用多张卡时，您需要使用 Xinerama 模式。这里有很多详细信息：
答案2
我尝试了几种不同的 xorg.conf，但都失败了。
这对我有用。我创建了一个文件 ~/.xsessionrc，其中包含以下行...
xrandr --output DVI-D-2 --right-of DVI-D-1
您的系统上的名称 DVI-D-2 和 DVI-D-1 可能不同。
您可以使用以下命令列出它们
xrandr -q
答案3
您是否尝试过使用 NVIDIA 驱动程序而不是 nouveau？
如果您确实使用 NVIDIA 驱动程序，则可以安装 nvidia-settings 包，它将为您提供一个 GUI 配置面板。您正在寻找名为“TwinView”的设置
