[Bug 327428] Re: mouse pointer no longer has 1 pixel precision

[Bryce Harrington]

However, the diagnosis done by Aielyn is sound, it just needs a more
sophisticated patch.

I've coded up this patch which adds a configurable option to disable the
touchpad resolution detection functionality.  With this turned on it
should have the same effect as Aielyn's patch.  This way, we can use
this workaround only on hardware that requires it.

Title:
  mouse pointer no longer has 1 pixel precision

Status in “xserver-xorg-input-synaptics” package in Ubuntu:
  In Progress

Bug description:
  Binary package hint: xserver-xorg-input-synaptics

After upgrading to the latest X server and all of the accompanying packages (version 0.99.3-2ubuntu2 for xserver-xorg-input-synaptics) there are certain rows and columns of pixels that I cannot move my mouse to.  The unreachable rows and columns are independent of anything else including where my mouse has been, what is being displayed there, and they are even consistent after reboots.

I am running the 2.6.28-6 amd64 kernel on the latest jaunty.
