[前置条件]
在鲲鹏物理服务器安装带UKUI的基于openEuler操作系统
[步骤]
1、通过显示器登陆,打开终端;
2、通过命令xrandr调整屏幕亮度(0——10):
xrandr --output VGA-1 --brightness 0.5
xrandr --verbose| grep ness
说明:--output [显示器名称] --brightness [屏幕亮度值]
--verbose 显示各个显示器名称和属性
3、通过xgamme命令调整屏幕亮度(0——10):
xgamma -gamma 0.7
[预期结果]
通过xrandr或xgamma命令调整数值,屏幕亮度会随着数值变化
[实际结果]
通过xrandr或xgamma命令调整数值,可以看到数值有变化,但是屏幕亮度无变化
