我还能做什么来禁用未使用的内部笔记本电脑显示屏
获取显示
$ xrandr -q | grep -e " connected"
LVDS1 connected 1366x768+0+2160 (normal left inverted right x axis y axis) 280mm x 160mm
DP2 connected primary 3840x2160+0+0 (normal left inverted right x axis y axis) 600mm x 340mm
禁用内部
$ xrandr --output LVDS1 --off --verbose
crtc 1: disable
screen 0: 3840x2160 1001x563 mm 97.34dpi
但它仍然存在
$ xrandr -q | grep -e " connected"
LVDS1 connected 1366x768+0+2160 (normal left inverted right x axis y axis) 280mm x 160mm
DP2 connected primary 3840x2160+0+0 (normal left inverted right x axis y axis) 600mm x 340mm
