Title:
  Touchpad speed scales with multimonitor size per axis

Status in XOrg-Driver-Synaptics - synaptics driver for XOrg:
  Fix Released
Status in xserver-xorg-input-synaptics package in Ubuntu:
  Incomplete

Bug description:
  When enabling a second screen, say horizontally next to the primary
  screen, horizontal touchpad speed increases proportionally to the
  increase in horizontal resolution. I assume the same happens when
  enabling multiple screens in a vertical configuration. So, it seems
  that touchpad speed is relative to the total screen layout size in
  each axis. This is quite irritating. It would be more reasonable to
  define speed in absolute terms (pixels/sec) rather than relative terms
  (% x/y resolution / sec), thereby keeping speed in both axes constant,
  regardless of the addition/removal of extra screens.

  I've noticed this on my Thinkpad W510 running Maverick amd64, the
  latest nvidia binary blob, utouch 1.1, synaptics-dkms 1.0.0, and
  xserver-xorg-input-synaptics 1.2.2-2ubuntu5

  Note that external mice don't exhibit this problem. This might be why
  this situation isn't encountered often: when plugged into an external
  monitor, the user is more likely to also plug in an external mouse
  rather than rely on the touchpad.
