简短解释：

简而言之，问题是无法将显示分辨率更改为我想要的分辨率，但在 Windows 中却可以。我尝试使用 xrandr，但失败并出现错误BadMatch。之后，我尝试X -configure在 root shell 中创建一个 xorg.conf 文件，但失败并出现错误Number of created screens does not match number of detected devices. Configuration failed. 我如何更改屏幕分辨率？

我的设置

首先我要声明，我是 ubuntu 新手，刚刚安装了系统和 nvidia 驱动，如下所示这些步骤现在我认为相关的系统规格：

$ lsb_release -a
No LSB modules are available.
Distributor ID: Ubuntu
Description:    Ubuntu 16.04.1 LTS
Release:    16.04
Codename:   xenial

CPU：i5-4460
GPU：GTX 970
1. 显示器：acer M230HDL（运行正常）
2. 显示器：Philips 190S8（分辨率错误时运行正常）包含大量信息的手册。

4.

$ xrandr --addmode DVI-I-1 1280x1024_60.00

Minor opcode of failed request:  18 (RRAddOutputMode)

第二次尝试

  1. 启动到 root shell。
  2. 制作/读写mount -o remount,rw /
  3. $ X -configure
some output (will add if asked)
Number of created screens does not match number of detected devices. Configuration failed.

问题

我到底怎样才能
a) 获取可与我的第二台显示器配合使用的模式行？
b) 获取我可以编辑的 xorg.conf，以便我可以更改其中的分辨率？
