[maemo-developers] How can I lock the touch screen and keys from software?

[From: Dustin DeWeese]

How can I lock the touch screen and keys from software?  I could not find a way to do this in the Maemo 4.x APIs.

I want to write a program to lock the screen and keys when the light sensor value drops, and unlock when the light sensor value rises.  This way, the N810's case would work like the N770's slide cover (unless you are in the dark).

Thanks,
Dusty
