Hi Florian,

I meant stored in memory by xorg. I have no knowledge one way or
another about boot-to-boot persistence of touchpad settings. My main
point was a practical one: Whatever your touchpad's settings are, you
can toggle it on and off with my script.

I can tell.

Like I said, I have no knowledge about boot-to-boot persistence, but if
I were just taking wild guesses, I'd guess that the touchpad itself has
some non-volatile RAM to store its settings, and the OS, when it boots,
reads those settings.

Keep in mind I've never noticed boot-to-boot persistence. In fact, if I
remember correctly, my laptops have always booted up to a fully
functional touchpad, which I had to suppress most of the time with my
shellscript.

And don't bring me down Bruce!

If you don't get the reference, that's OK, you need to be over 60 to
get it.
