linux下开启键盘背光

中午闲来无事，在linux下驳接了个小背光键盘，想试试能否开启背光；结果悲催的是废了九牛二虎之力，还是点不亮背光。

一怒之下，放狗搜，然后就有了下文

xset  usage:xsetTo set LED states off or on:    -led [1-32]              led off     led [1-32]              led on    -led named 'name'        led off     led named 'name'        led on

譬如要开启Scroll Lock灯

xset led named 'Scroll Lock'

关闭

xset -led named 'Scroll Lock'

然后，下面是前人的工作，便参考：
