VGA-1 disconnected (normal left inverted right x axis y axis)
HDMI-1 disconnected (normal left inverted right x axis y axis)
DP-1 disconnected (normal left inverted right x axis y axis)
也可以使用命令
xrandr |grep " connected"|cut -f1 -d " "
通过--brightness选项来调节屏幕的亮度
屏幕的亮度参数是从0.1到1.0, 从暗到亮
xrandr --output LVDS-1 --brightness 0.8
方法二:
只对intel显卡有效(自己没测试)
xbacklight -set [porcentaje-brillo]
如果想调节屏幕亮度为80%,可以执行
xbacklight -set 80
也可以增加或减少百分比
xbacklight -inc 10 #增加10%
xbacklight -dec 10 %减少10%
