Thinkpad T440s keyboard backlight

A while back I made a simple python script to get the keyboard backlight of the laptop to dynamically switch on and off. Normally you control the backlight with a key combination. But I prefer to only have backlight when I'm typing.

The newer version of the script uses the /sys kernel interface to change the backlight. The older version was quite a hack, poking around some bytes. You can still find it on github.

The newer version can be found on github as well:

I hope it is useful for someone :)
