我使用的是 Ubuntu MATE 18.04。
我相信它使用 LightDM 作为显示管理器。我有 2 台显示器连接到同一设备（Intel HD 板载显卡，有 2 个端口，1 个 HDMI，1 个 VGA）。
由于我运行的应用程序的性质，我需要有 2 个独立的 X11 屏幕。我需要在它们之间移动鼠标，但除此之外它们应该是独立的。我不应该能够在显示器之间移动窗口。
我相信采用一个显示器和两个屏幕（每个屏幕一个显示器）的设置是可行的。
使用显示管理器 GUI 应用程序，我只需扩展一个显示器，并且它位于同一屏幕上。
我是否正确地认为一台显示器、2 个屏幕、每个屏幕一台显示器就能满足我的要求？
我该如何设置它？
我正在遵循本指南：
- 双显示器 （位于 Gentoo Linux Wiki）
还
Ubuntu 中采用 Intel HD 显卡的双屏设置（在询问 Ubuntu）
Xorg：独立模式（在 Unix 和 Linux 上）
在一张卡上配置多个 X 屏幕 （在 nvidia.com）（这没有提到 ZaphodHeads）
它接缝我想要的是所谓的 ZaphodHeads – 同一设备的多个屏幕。
然而，我得到的结果是 2 个空白屏幕，只有文本光标位于左上角。
在我看来这就是问题所在：

两个屏幕都是黑色的，光标位于左上角。
我需要配置 LightDM 才能接受此设置吗？
答案1
我对您想要的设置有很多经验。您必须制作自定义 xorg.conf。如果您有英特尔图形适配器 ZaphodHeads 就是您的方法。这是一个例子：
Section "ServerLayout"
Identifier "LayoutDual"
Screen 0 "ScreenR" 0 0
Screen 1 "ScreenE" RightOf "ScreenR"
EndSection
Section "ServerFlags"
Option "DefaultServerLayout" "LayoutDual"
EndSection
Section "device"
Identifier "IntelR"
Driver "intel"
#Option "AccelMethod" "sna"
Screen 0
BusId "PCI:0:2:0"
Option "ZaphodHeads" "eDP1"
Option "NoAccel" "true"
EndSection
Section "device"
Identifier "IntelE"
Driver "intel"
Screen 1
BusId "PCI:0:2:0"
Option "ZaphodHeads" "HDMI2"
Option "NoAccel" "true"
EndSection
Section "Monitor"
Identifier "MonitorE"
VendorName "Vendor"
ModelName "Model"
Option "Rotate" "right"
EndSection
Section "Monitor"
Identifier "MonitorR"
VendorName "Vendor"
ModelName "Model"
EndSection
Section "Screen"
Identifier "ScreenE"
Device "IntelE"
Monitor "MonitorE"
Option "Rotate" "right"
DefaultDepth 24
SubSection "Display"
Depth 24
EndSubSection
EndSection
Section "Screen"
Identifier "ScreenR"
Device "IntelR"
Monitor "MonitorR"
DefaultDepth 24
# Option "DPI" "96 x 96"
SubSection "Display"
Depth 24
Modes "2048x2048"
EndSubSection
EndSection
输入lspci命令行以查看图形适配器连接的位置。它在 BusId 中定义。如果你有更多，这会非常有用。如果您只有一个，则它是可选的。键入xrandr，查看您的驱动程序可以识别哪些输出。示例中加速器被禁用。如果需要，您可以启用它们。您可以制作更多布局，然后指定将在DefaultServerLayout部分中使用的布局。
这是一个 NVidia 示例：
Section "ServerLayout"

Screen 0 "ScreenR" 0 0

答案2
你们有startx/xinit作为单一程序吗？
杀死 LightDM，阅读其手册页xinit，然后我认为您应该能够做您想做的事情（不，我不认为 LightDM 是为了支持这种用法而编写的。）
它可能包括编写定制的xorg.conf.
答案3
我在使用 Xfce 的 Debian-11 上遇到了同样的问题（两个空白屏幕，只有光标）。我设法通过在 xorg.conf 中强制使用“模式设置”驱动程序（而不是 intel）来解决这个问题，如下所示
Section "Device"
# Identifier "Intel Graphics"
# Driver "intel"
Identifier "Modesetting"
Driver "modesetting"
Option "AccelMethod" "sna"
EndSection
为什么它解决了我的问题？
我在 xorg.log 中发现的错误如下
xf86EnableIOPorts: failed to set IOPL for I/O (Operation not permitted)
通过谷歌搜索上述错误消息，我找到了
https://github.com/dnschneid/crouton/issues/2926
接受了一些提示并尝试了一下（尽管该页面处理完全不同的问题），瞧！有效。
