Nvidia：强制将 1920x1080 作为选项

gentoo 上的专有 Nvidia (290) 在此处。

我在这里运行 Nvidia TwinView，带有两个 1680x1050 显示器。现在我想在 HDTV 和其中一个显示器之间进行热插拔。几乎没问题，但由于 Nvidia 读取了显示器的 EDID 信息并看到最大分辨率为 1680x1050，因此它不允许 1920x1080。“检测显示器”没有nvidia-settings任何作用。到目前为止，我唯一的选择是重新启动 X，但这是高度不可取。

我已经发现可以用 来做一些我喜欢的事情MetaModes，但它也不允许更大的分辨率。

我想我必须放弃 EDID 信息并手动指定模式。但是到目前为止，TwinView 还不喜欢我提供的内容。

经过足够的调整后，我能够获得 1920x1080 作为 CRT 输出选项。为什么它不适用于 DVI，我不明白。所以这只是一个 80% 的解决方案：现在我可以随时更换显示器，但使用次优的 VGA。我已经完成了这个调整，并订购了一台有三个连接器的现代 GT520。

这是当前的xorg.conf。我使用该软件获得的显示器自定义模式parse-edid。
