我的核心问题是，我试图让 HTPC 在电视上启动 X，即使电视在计算机启动时处于关闭状态。这需要对 /etc/X11/xorg.conf 进行（少量）调整，但为了真正做到这一点，我需要一个基本的 xorg.conf 来工作。
因此我运行“Xorg -configure”，得到了以下结果：

因太长而被剪掉。
有没有一种简单的方法可以获取默认的工作 xorg.conf，以便我可以开始编辑它？我只想添加模式行并强制使用 HDMI-1。
答案1
我设法通过将驱动程序替换为 i9xx 驱动程序来运行探测，但事实证明，探测甚至没有必要。与我的想法不同，我不需要整个部分树（监视器、屏幕和设备）。仅监视器部分就足够了：
下面的xorg.conf方法对我有用：
Section "Monitor"
Identifier "HDMI-1"
VendorName "LG"
Modeline "forced" 148.50 1920 2008 2052 2200 1080 1084 1089 1125 +hsync +vsync
Option "Primary" "true"
Option "PreferredMode" "forced"
Option "Enable" "true"
Option "IgnoreEDID"
EndSection
模式行几乎逐字逐句地取自成功运行（即，电视打开时）的 Xorg.0.log。
