On my machine (a Lenovo X1 Carbon), my palms frequently touch the
corners of the clickpad while I'm typing; palm detection is broken
because the kernel keeps reporting a finger width of zero. (See
https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1245328.) Even if
palm detection were working, though, I don't think it'd help: z-values
seem to be about the same when I'm using the trackpad and mashing it
while typing.
