戴尔XPS 13 9343 – 启动Ubuntu 15.10时键盘背光
我从Ubuntu 15.04升级到Ubuntu 15.10，现在在第一次启动时键盘背光打开。 我可以手动将其关闭，但不会记住该设置，下次启动会导致键盘背光打开。
如何将行为更改为：
- 记住最后的设置
要么
- 默认为关闭？
此后我在登录/恢复时使用的脚本：

（更新时间：2015年12月23日修复符号链接报告命令+添加启动板问题参考）
（更新时间：2015年12月23日少管道+ / usr / local / bin）

我设法通过/etc/init.d的脚本使用以下行停止第一行：
echo 0 | tee -a /sys/class/leds/dell\:\:kbd_backlight/brightness
但第二个没有运气。
