我正在尝试让 ubuntu 运行 3 个显示器。我已获得 2 个视频卡
linux - linux系统删除 VGA
20:01:00.0 VGA compatible controller: ATI Technologies Inc RV620 LE [Radeon HD 3450]
25:05:00.0 VGA compatible controller: nVidia Corporation NV44A [GeForce 6200] (rev a1)
我曾经在两个显示器正确插入 ATI 的情况下让它工作，而 nVidia 显示器则空白。现在我让 nVidia 显示器工作，让一个 ATI 显示器工作，但我似乎无法让最后一个显示器显示任何东西。它确实显示了启动屏幕，并且一直工作到您看到 ubuntu 的登录屏幕，然后它消失并且 nVidia 显示器打开。我的 xorg.conf 可能出了问题吗？或者我需要做更多的事情才能让它工作？
目前我在我的 Xorg.0.log 文件中看到了这个错误，但我不确定接下来该怎么做：
[ 24.746] (EE) RADEON(2): reusing fd for second head

答案1
首先在您的 ServerLayout 部分中您将其显示为：
Screen 0 "Screen0" 0 0
Screen "Screen1" RightOf "Screen0"
Screen "Screen2" RightOf "Screen1"
您缺少屏幕标签。您需要它看起来像下面这样。
Screen 0 "Screen0" 0 0
Screen 1 "Screen1" RightOf "Screen0"
Screen 2 "Screen2" RightOf "Screen1"
您文章中的其他所有内容在 xorg.conf 中看起来都是正确的。我看到的唯一其他问题是您正在运行 nvidia 和 ati 视频芯片组。原因是，我知道 Nvidia 网站上的驱动程序将删除一些 ATI 所需的驱动程序。除非您想使用开放的 nvidia 驱动程序或 vesa 来管理第三台显示器。
请发布您的 Xorg.0.log，我将能够为您指明正确的方向。
答案2
我注意到您将一个“Monitor”部分（对于“Dell1”）的结尾与另一个“Monitor”部分（对于“Dell2”）的开头合并在一起，因此该行如下所示：
Section "Monitor"
Identifier "Dell1"
VendorName "Unknown"
ModelName "Unknown"
HorizSync 30.0 - 81.0
VertRefresh 56.0 - 76.0
Option "DPMS"
EndSection
Section "Monitor"
Identifier "Dell2"
VendorName "Unknown"
ModelName "Unknown"
HorizSync 30.0 - 81.0
VertRefresh 56.0 - 76.0
Option "DPMS"
