Offing One's Touchpad

[utu]

@ Klaus2008

Your one-line solution works like a charm.
I am mystified, since xorg.conf is UNCHANGED.
Even so, the laptop's touchpad IS turned off.
It is gone for both root and knoppix users.

The only problem I see is one would have to
review the /etc/X11/Xsession.d/ entries to have
a clue that a change was made and how to undo it.

Is there a way to transfer a comment on 15x11 to
the changed xorg.conf so as to alert folks to
what's been done?

Anyway, the enormous praise and great fame are
well deserved. Thanks much.

Umm ...

You've got /etc/X11. In there are (amongst others), are a configuration file and two scripts:

xorg.conf
Xreset
Xsession

and three directories:

xorg.conf.d
Xreset.d
Xsession.d

So if you wanted to put a comment somewhere to the effect you'd added a script to Xsession.d you'd put it in Xsession, not xorg.conf.

But since the whole point of the directory Xsession.d is so that packages and people can add stuff to the X session start-up without actually editing the file Xsession (so that it too can be upgraded sans sourci), adding comments to Xsession to say you'd added something in Xsession.d might be seen as rather missing the point.
