Have installed both this package and synaptics-led.
Now touchpad's locking works fine. LED still doesn't work, so will be happy to hear about any updates.

@dgbaley27: thanks for helping!

I installed this package and the synaptics-led package about a month ago and it worked perfectly. But after I updated all my packages on my system about a week ago, the feature to disable and enable the touchpad with a double tap on the LED has stopped working. The touchpad still works fine. Is there an updated package which cause this problem? Am I the only one who have this problem after installing the newest packages?

The package can't compile!
Here it fails:

Hmm, I'll take a quick look but I might just orphan this.

The following line should be added to synproto.h before all other include directives:
#include xorg-server.h
