[gentoo-user] How to stop mouse motion

["Jorge Peixoto de Morais Neto" <please.no.spam.here@gmail.com>]

Hi. I have a crappy mouse made in China. One of its problems is that
the mouse pointer sometimes moves even while the mouse is not moving.
Usually this manifests by the pointer "shaking", moving back and
forward one or two pixels very fast (it looks like some 5 times per
second).  The worst problem caused by this is that the monitor can
wake up at seemingly random times.

One solution would be to switch off the monitor every time I won't use
it for a few minutes, but (AFAIK) this would waste energy and reduce
lifetime. I want the DPMS modes of standby, suspend, off.

Another solution would be to buy another mouse, but this would cost
money and would not teach me the solution (this problem can manifest
again in the future, with this or another computer).

So I want a way to tell the kernel or X11 to ignore mouse motion.
Either to shut down mouse motion completely, or to allow it but to
ignore it for the effect considering the computer as idle. I have
performed a quick read of kernel code and of the xorg.conf man page
but I see no clue.

Anybody knows?
