Xrandr 显示 HDMI1 断开连接，HDMI2 作为主显示器，且只有一个显示器

我不确定为什么 Xrandr 的输出显示 HDMI1 断开连接而 HDMI2 连接为主端口。我当前的设置中只有一个显示器和一个 HDMI 端口。根据下面的代码片段，我使用的是带有 i915 驱动程序的 Intel HD Graphics 500 芯片组。我是否遗漏了 HDMI1 断开连接的原因，甚至没有注意到为什么有 HDMI2？

无需担心额外的 HDMI 显示器名称

只要一切正常，您就不必担心如何xrandr分配监视器名称。

以我的设置为例：

$ xrandr | grep connected

HDMI-0 connected 1920x1080+0+0 (normal left inverted right x axis y axis) 1107mm x 623mm
eDP-1-1 connected primary 1920x1080+0+1080 (normal left inverted right x axis y axis) 382mm x 215mm
DP-1-1 connected 1920x1080+1920+532 (normal left inverted right x axis y axis) 708mm x 398mm
HDMI-1-1 disconnected (normal left inverted right x axis y axis)
DP-1-2 disconnected (normal left inverted right x axis y axis)
HDMI-1-2 disconnected (normal left inverted right x axis y axis)

一切正常，我并不担心 HDMI-1 有重复的名称并显示为“断开连接”。

更好的方法是使用：

$ xrandr | grep " connected "

HDMI-0 connected 1920x1080+0+0 (normal left inverted right x axis y axis) 1107mm x 623mm
eDP-1-1 connected primary 1920x1080+3840+2160 (normal left inverted right x axis y axis) 382mm x 215mm
DP-1-1 connected 3840x2160+1920+0 (normal left inverted right x axis y axis) 1600mm x 900mm

这种技术可以使您免于筛选“断开连接的”监视器，更重要的是，它不会造成太大的混乱。
