Okay, this is interesting. I found that I can confirm this bug on Saucy
using the 3.8.13.12 mainline kernel version, which according to
http://kernel.ubuntu.com/~kernel-ppa/info/kernel-version-map.html is
equivalent to the 3.8.0-34.49 kernel I used in my test of updated Raring
(and there was no bug there). I expected the 3.8.13.13 kernel to exhibit
the bug (it does as well) and the 3.8.13.12 kernel to not show it based
on what I saw in Raring, so this surprised me.

Is it possible that this bug is not due to the kernel?

Title:
  [Fujitsu  LIFEBOOK T900] Stylus input stops working after resuming
  from suspend

Status in “linux” package in Ubuntu:
  Incomplete

Bug description:
  I'm filing this bug here as per a suggestion on Ask Ubuntu:
  http://askubuntu.com/questions/377047/which-package-should-i-file-a
  -bug-against-for-pen-input

  I have a Fujitsu LifeBook T900 which accepts touchscreen input via a
  stylus which comes with the machine. It works fine until I suspend the
  laptop, such as by closing the lid, then resuming, at which point it
  immediately stops working.

  Keyboard and touchpad (mouse) still work while the bug is active. This
  is a fresh install of Ubuntu 13.10; the same machine previously ran
  12.04 LTS and did not experience the problem there.

  WORKAROUND: Restart or log out and back in.
