Xorg 服务器配置失败 - 未检测到屏幕

我在 ubuntu 12.04 (带有 nvidia 420M GT 卡) 上使用 Xorg 服务器时遇到了严重问题。

在家里，我使用连接到笔记本电脑 HDMI 端口的外接显示器 - 外接显示器用作扩展。但是当我离开家去上班时，我不再使用它，但我的 xorg 配置文件保持原样，然后发生了一些不好的事情。例如 - 每次断开外接显示器后启动时，我都会得到一些非默认字体，并且比平时更大 + 一些窗口带有关于不兼容分辨率模式的错误。

但今天我尝试在没有附加监视器的情况下正常启动，但 xorg 服务器失败了，我无法启动到 GUI。我收到了此信息

我还收到错误，提示已检测到屏幕，但没有一个具有正确的配置文件，但随后我尝试使用以下方法将 xorg 重置为其默认值（在故障安全模式下）：

sudo dpkg-reconfigure xserver-xorg

（我没有得到任何输出）现在我被这个问题困住了。说实话 - 当我尝试登录failsafe模式并在尝试正常启动时获取 ubuntu 启动图像时，我遇到了这个错误。

这是我的配置文件xorg.conf：

好的，我已经重新安装了xserver-xorg，apt-get然后删除了~/.config/monitors.xml文件，现在一切正常。:)

（监视器文件就像连接外部显示器后的一个神器，它会以某种方式存储设置，并在您切换回一种显示模式时导致问题http://ubuntuforums.org/showthread.php?t=1917220）
