我正在尝试为我的戴尔 G5 笔记本电脑设置第二台显示器。
Ubuntu 版本 18.04 LTS。
然而，我对此感到震惊：
到目前为止我尝试的是：
下载 Gnome-Tweak-Tool 和选定的工作区跨度显示。
使用命令行重新安装 gnome 设置
sudo apt-get install compizconfig-settings-manager
没有工作。有人可以帮我吗？

更新：2019/03/11 我尝试安装较新的 Nvidia 驱动程序并测试了其中的几个。它不起作用，最新的一个打破了我的分辨率和刷新率设置，即使在我恢复驱动程序之后也是如此。我尝试从闪存驱动器重新安装 Ubuntu。但是，这也不起作用。它修复了分辨率/刷新率问题，但不是原始问题。回到原点。
