即使没有连接电缆，xrandr 也会报告外部 VGA 输出已连接

我有一台运行 Karmic 的机器，它嵌入在一台大屏幕上。当我运行 时xrandr -q，它报告 VGA 输出已连接，即使没有连接屏幕。这导致其他与分辨率相关的软件出现一些问题（我目前无法更改）。

有没有办法禁用 VGA 输出，使其完全不显示，或者是否有一些我可以反向移植的修复程序，以便它不再错误报告？以下是有关系统的一些信息。据我所知，这种情况只发生在这个硬件上。

添加后

Option "monitor-VGA" "VGA"

在 xorg.conf 的“设备”部分中，添加以下“监视器”部分：

Section "Monitor" 
    Identifier "VGA" 
    Option "Ignore" "True" 
EndSection

这将告诉 X 忽略输出。
