检测正确分辨率双显示器 VGA 9800gt Ubuntu 12.10

我在 VGA 端口上将第二台显示器连接到我的 9800gt。第一台显示器使用 DVI。两台显示器的原始分辨率均为 1920x1080，但第二台显示器的分辨率不超过 1360x768，在显示设置中显示为“未知”。

我尝试过这个指南如何添加未检测到的分辨率但它不起作用。

首先，我创建新模式，xrand --newmode "1920x1080_60.00" 173.00 1920 2048 2248 2576 1080 1083 1088 1120 -hsync +vsync然后当我尝试将新模式添加到第二台显示器时，randr --addmode VGA-0 1920x1080出现以下错误：

X Error of failed request:  BadMatch (invalid parameter attributes)
  Major opcode of failed request:  140 (RANDR)
  Minor opcode of failed request:  18 (RRAddOutputMode)
  Serial number of failed request:  31
  Current serial number in output stream:  32

我尝试使用 nvidia-settings 面板生成xorg.conf：

这是我的 xrandr 输出，希望它有帮助：

下一步该做什么有什么想法吗？我已经尝试了几个小时，但没有成功，它在 Windows 上运行良好，所以不可能是电缆或显示器的问题...

我认为您需要做的是禁用 EDID 探测。方法因图形芯片组/驱动程序而异。例如，对于 nvidia 的二进制 blob 驱动程序，您可以使用“选项“IgnoreEDID”“false”。这会出现在您的显示器配置部分中。YMMV。
