NVidia 驱动程序后分辨率错误

我遇到了一些 NVidia 驱动程序问题。当我安装 Ubuntu 14.04 时，屏幕分辨率无法检测到 1280x1024 模式。我使用 xrandr 创建了 1280 x 1024 模式。安装 NVidia 驱动程序后，我无法将分辨率设置为 1280x1024。检测到了错误的分辨率。

如果我运行 xrandr：

当我尝试添加新模式时：

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

由于我使用了 D-sub 适配器，因此我的连接不是 DVI。

你可以尝试一下，打开这个文件

sudo gedit /etc/X11/xorg.conf

并将此行添加到设备部分

Option"ModeValidation" "NoMaxPClkCheck"

然后重启
