我最近把Ubuntu18.04和windows 10一起安装在我的笔记本电脑上。不幸的是，连接到HDMI-1的外部监视器没有在Ubuntu上工作(未被检测到)。我几乎什么都试过了这里和这里。它与HDMI到VGA_适配器连接。我的显卡是GeForce GTX 1650，我试着从NVidia下载这驱动程序。另外，正如您在图片中所看到的，在屏幕显示设置中，它甚至没有显示屏幕布局。

在Ubuntu14.04(我的旧笔记本电脑)上，我过去曾通过使用以下方法解决过类似的问题：

echo $myNewMode
## Output: "1368x768_60.00" 85.25 1368 1440 1576 1784 768 771 781 798 -hsync +vsync
xrandr --addmode eDP-1 $myNewModeName
xrandr --output eDP-1 --mode $myNewModeName --output HDMI-1 --auto --right-of eDP-1

但是，这也没用。有什么想法吗？

更新:我运行了X -configure (只运行主屏幕)，提到了这里，还运行了nvidia-xconfig (只有HDMI )。不知何故，nvidia似乎取得了最近创建的文件xorg.conf.new，并从中获得了自己的xorg.conf。不过，如果我拔掉HDMI，一切都是空白的。至少现在我可以在nvidia x server settings应用程序窗口上看到一个屏幕布局(HDMI)和内容(以前是空白的)。

下面是最新的xorg.conf文件：

# nvidia-xconfig: X configuration file generated by nvidia-xconfig
# nvidia-xconfig:  version 440.26
