我确信这属于另一个堆栈站点，但我不知道哪一个。
不管怎样，我已经使用 Arch 和双显示器一段时间了，最终，系统升级不知怎么地毁了我的视频驱动程序，我只能使用一个显示器。我处理了一段时间，但后来它停止启动了。我喜欢 Arch，但没有时间。
我切换到带有 Xfce 的 Debian，但似乎无法识别第二台显示器，有人可以告诉我正确的堆栈，或者只是提供一些帮助吗？

经过一个周末的工作，我设法在 Arch 上完成了这项工作，但我希望 Debian 对我来说会更容易一些。
我可以提供更多输出。上次加载 Arch 时，CLI 显示两个监视器，但 Xfce 没有。
非常感谢！我花了大约一天的时间向一位朋友提供了一个新的简单商业网站（朋友价——免费 :)），他也会很感激。
如果有人告诉我 Gnome 可以神奇地解决所有问题，我可以重新安装，但是我已经开始喜欢 xfce 了。
谢谢！
编辑：我认为断开连接的原因是 lspci 看到了额外的视频卡，而 xandr 却看不到......

我个人使用带有 xrandr 的开源 nvidia 驱动程序来处理我的双屏。
唯一的配置是在我的 .xinitrc 中：
xrandr --output DVI-0 -s 3840x1080
xrandr --output DVI-0 --mode 1920x1080
xrandr --output DVI-1 --mode 1920x1080
xrandr --output DVI-0 --left-of DVI-1
您可能需要进行一些修改以使其适合您的设置。
编辑
在你的主目录中你有一个.xinitrc文件。该文件由启动命令或连接管理器（如slim）。
我不知道你使用什么连接管理器，但假设你使用启动你必须编辑你的命令.xinitrc文件并在启动 xfce4 之前添加前面的几行。
我在运行 xfce4 的 archlinux 机器上拥有的 .xinitrc 文件示例：
# ~/.xinitrc
#!/bin/bash
xrandr --output DVI-0 -s 3840x1080
xrandr --output DVI-0 --mode 1920x1080
xrandr --output DVI-1 --mode 1920x1080
xrandr --output DVI-0 --left-of DVI-1
exec startxfce4
