X 在启动时读取监视器和布局配置，但 xrandr 只显示 Screen0

我已经设置 arch linux 几天了 - 大多数情况下很容易取得进展，但我在多头支持方面遇到了真正的问题。

我有一台 Thinkpad X1 Extreme，配备 Intel 和 NVIDIA 视频芯片以及混合显卡

我已经安装了：

  • xf86-视频-英特尔
  • xf86-视频-vesa
  • 熊蜂
  • BB开关
  • 光DM
  • i3wm

这是我正在使用的 xorgconf：

这是两个视频设备的 lspci -v 输出：

当我启动时，X 似乎可以正常选择布局和屏幕（之前我很难让它阅读第一个屏幕部分）：

bbswitch 似乎可以识别和管理这两个视频设备，尽管存在某种问题：

（dmesg 整个输出的 Pastebin）

xrandr但仍然xrandr --listproviders只显示 1 个屏幕和 1 个提供商：

$ xrandr
Screen 0: minimum 320 x 200, current 1920 x 1080, maximum 8192 x 8192
eDP1 connected primary 1920x1080+0+0 (normal left inverted right x axis y axis) 344mm x 194mm

   1680x1050     59.95    59.88  
   ...

$ xrandr --listproviders
Providers: number : 1
Provider 0: id: 0x43 cap: 0xb, Source Output, Sink Output, Sink Offload crtcs: 3 outputs: 1 associated providers: 0 name:Intel

我无法使用 xrandr 打开或移动显示器，因为启动后输出不可用（无论是否插入显示器）

答案1

我对此有一个解决方案：

我删除了 xorg conf 文件，这样它们就不会干扰，然后xrandr开始在屏幕 0 上显示虚拟输出。

我运行intel-virtual-output这导致屏幕闪烁，并xrandr显示很多更多的虚拟输出，其中 ( VIRTUAL3) 之一已连接。

之后，我可以设置其模式，显示屏打开并显示工作区。

分辨率非常错误，我无法创建具有正确分辨率的模式，但这是另一个问题。
