linux下开启键盘背光
返回主页
使用linux总有一个烦恼,在win下正常使用的键盘背光到了linux下就跪了.究其原因还是linux内核对键盘的支持不好.
默认在win下按下键"scroll"即可打开背光.
查找一些资料之后发现可以通过bash脚本实现对键盘背光的控制
代码如下
num - 0, caps - 0, scroll - 0 LED mask: 00000000
num - 0, caps - 1, scroll - 0 LED mask: 00001001
num - 1, caps - 0, scroll - 0 LED mask: 00000002
num - 1, caps - 1, scroll - 0 LED mask: 00001003
num - 0, caps - 0, scroll - 1 LED mask: 00000004
num - 0, caps - 1, scroll - 1 LED mask: 00001005
num - 1, caps - 0, scroll - 1 LED mask: 00000006
num - 1, caps - 1, scroll - 1 LED mask: 00001007
leds=
xset q | grep LED | cut -c66
case $leds in 0 | 1 | 2 | 3 ) xset led 3 ;; 4 | 5 | 6 | 7 ) xset -led 3 ;; esac
