I have a Lenovo laptop with a trackpoint and a touchpad. I much

(Leaving the touchpad fully enabled is no good; palm detection is
spotty at best.)

I'm a little surprised that this apparently can't be done in the XI2
core. Is there a better way?
You should be able to get the same effect by setting ConstantDeceleration on
your device to something really high (50 or so will likely do). The touchpad
will still submit motion events, but x/y pointer movement will be slowed
down enough to never actually change.
would that work for you?
That seems to work. The docs are a bit misleading IMO, though -- this
decelerates by a factor much more than 50.
Are there any easy-to-use hotplug-aware tools for setting XI2
properties on a per-device basis? Doing this in xorg.conf seems kind
of sad.
why? that's what the InputClass sections were designed for - give you
configuration that works on a class of devices, even when hotplugged.
your desktop environment could handle this in the client, but afaik none
of the major ones currently do set this particular setting.
so putting a snippet in xorg.conf.d is certainly the best and most
appropriate solution.
Cheers,
Peter
