附加监视器的 Xorg 配置

我一直在努力让第三个屏幕工作，但在更换显示器后就停止了（以前这在 USB displayLink 上确实有效）。我在启动时遇到了 EDID 错误，所以现在我生成了自己的 xorg.conf 文件，如下所示。屏幕现在启动了，但显示一个 ubuntu 加载屏幕，显示“已启动 Light Display Manager”，但在屏幕设置中无法识别。

我认为 ubuntu 会忽略 xorg.conf。你可以把这些内容放进去/usr/share/X11/xorg.conf.d，但最好使用 xrandr 或 arandr 或 unity-control-center 来配置你的显示器。
