For me it works perfectly with xbacklight.
If you for example wish to set up a key binding, you can use
对我来说，它与xbacklight. 例如，如果您希望设置键绑定，则可以使用
bindsym $SUPER+Shift+plus exec xbacklight -inc 10
bindsym $SUPER+Shift+minus exec xbacklight -dec 10
in your window managers config (I use i3) to regulate your screen's brightness level.
在您的窗口管理器配置中（我使用 i3）来调节屏幕的亮度级别。
I wouldn't recommend xrandrfor this since it doesn't stop at 100% brightness automatically.
我不建议xrandr这样做，因为它不会自动停止在 100% 亮度。

if(!$br||$br>1) die("enter brightness lvl 0.1 - 1");
preg_match_all('!^(\S+)!m',`xrandr --current | grep ' connected'`,$m);
foreach($m[1] as $display){
echo `xrandr --output $display --brightness $br`."\n";
}
