![Ubuntu 18.04.2 LTS,HDMI 显示器无法识别](https://linux22.com/image/909690/Ubuntu%2018.04.2%20LTS%EF%BC%8CHDMI%20%E6%98%BE%E7%A4%BA%E5%99%A8%E6%97%A0%E6%B3%95%E8%AF%86%E5%88%AB.png)
你可以想象我对这种情况有点不高兴。
我在 Windows 和 Ubuntu 的双启动模式下运行,并且可以使用 Windows 10 上的第二台显示器正常工作。
但是,当我切换到 Ubuntu 时,显示器在显示菜单中无法识别(它只显示我的常规笔记本电脑屏幕)。我认为应该连接 HDMI 电缆,并且显示器自行供电。
该显示器是三星 syncmaster 226BW(我认为是较旧的显示器)。
笔记本电脑是 acer nitro 5。Ubuntu 是 18.04.2 LTS。
我认为我的笔记本电脑只有可用于显示器的 HDMI 端口......
我提前道歉,我不知道如何在 ubuntu 论坛中正确地将这些终端输出格式化为可读格式...这是我运行命令的一些ubuntu-drivers devices
输出
lauri@lauri-Nitro-AN515-51:~$ ubuntu-drivers devices
== /sys/devices/pci0000:00/0000:00:01.0/0000:01:00.0 ==

我尝试重新安装驱动程序但迄今为止仍无法解决问题。
下面是登录屏幕,但登录按钮附近的“齿轮菜单”中没有 xorg 东西,所以我只选择了常规 Ubuntu。其他选择似乎是我一直试图安装的某种 Ubuntu 主题,但我不确定它们是否与这个问题有很大关系。
下面显示了我认为正在使用的驱动程序,但是 nvidia x 服务器设置也由于某种原因显示空白屏幕,这似乎令人担忧......
我安装了 hwinfo 并运行命令“hwinfo --gfxcard”,这是输出
