卡在极低分辨率 800x600；原始分辨率 1680x1050

我知道很多不同线程的很多不同的人，但我无论如何也想不出如何解决这个问题。

我正在双启动 Windows 8/Ubuntu系统，并且最近更换了显示器。我正在使用专有驱动程序我的显卡是Nvidia GeForce 660 Ti，我使用的新显示器是 VX2025wm (点击此处查看手册）。

我知道显示器以其原始分辨率工作，因为在 Windows 8 上启动时它会自动调整为 1680x1050。我不确定这是否值得注意，但旧显示器默认会以更高的分辨率查看 GRUB，而这个显示器继续使用低分辨率直到启动到 Windows 8。

我真的束手无策了，我不太习惯 Ubuntu，而且我对 Linux 也没有太多经验。任何帮助都行大大赞赏。

我已经包括了我的xorg配置文件文件

答案1

经过一整天的工作，我得出的结论是，问题完全出在显示器上，VX2025wm一直有问题扩展显示识别码和DVI输入， 例如不显示原始分辨率，未找到信号错误，以及一堆其他不利于流畅计算环境的混乱小事。

解决方案是添加一个自定义 EDID到xorg配置文件文件：

Option         "CustomEDID" "DFP-0:/etc/X11/viewsonic.raw"

对于此特定的显示器，我可以在这里找到 EDID： http://blog.komeil.com/2008/06/fixing-edid-dvi-monitors-no-signal.html

我希望这能帮助那些遇到原始分辨率问题并且确信他们的显卡/驱动程序没有问题的人。
