DP-1-1 disconnected (normal left inverted right x axis y axis)
但当我尝试这样做时：
bussiere@kusanagi [22:03:53] [~/script] [master *]
-> % xrandr --output Screen\ 0 --primary
warning: output Screen 0 not found; ignoring
bussiere@kusanagi [22:04:49] [~/script] [master *]
-> % xrandr --output Screen 0 --primary
xrandr: unrecognized option '0'
Try 'xrandr --help' for more information.
它不起作用。请问如何正确输入 xrandr 的 --primary 命令的 Screen 0？
谢谢
答案1
这里的“屏幕 0”描述由这两个输出组成的整个虚拟显示：
- eDP-1-1：物理屏幕插入显示端口输出
- HDMI-1-1：物理屏幕插入 HDMI 输出
（注意屏幕 0宽度为 3286 像素，即 1366 + 1920，另外两个输出水平像素）
我猜你想用HDMI-1-1作为主要输出，以下命令将修复该问题：
xrandr --output HDMI-1-1 --primary
