在 kubuntu 上强制第二台显示器提高分辨率

我有一台 nvidia GTX 260 896 MB 和一台支持 1680x1050 原生分辨率的 Samsung 225 BW 显示器。我需要将分辨率添加并应用到 nvidia x 服务器设置视口输出到 1920x1080，但当我单击应用（模糊）时，它不允许我恢复到 1680x1050。我尝试使用 addmode 和 newmode 命令，但分辨率没有出现。在 Windows 10 上，它运行良好，可以将显示器保持在 1920x1080。

操作系统：Ubuntu KDE 14.04 LTS

在此处输入图片描述

这是我在 /etc/x11/xorg.conf 中所拥有的内容

我会安装 ARandR 并使用该 GUI，而不是 NVIDIA 或其他。对我来说，在 Ubuntu 版本的 Linux 上使用多台显示器设置和保持分辨率效果很好。

打开终端窗口并安装： sudo apt-get update && sudo apt-get install arandr

然后要开始使用，只需在应用程序菜单中找到 arandr 作为应用程序列出即可。

安装后，在菜单中找到它：系统->首选项->ARandR
