Comment 7 for bug 787781

I just installed Oneiric with todays latest updates on my x220 tablet, as well as the utouch related packages. The touchscreen worked fine with the pen device, but acted like a large touchpad when using my finger. I followed the steps in entry #29 in this ubuntu forum thread:
  http://www.ubuntuforums.org/showthread.php?t=1785015&page=3
 and now it works. The summary of steps is:
 1) downloaded xf86-input-wacom-0.11.1.tar.bz2 (the latest)
 2) run `./configure --prefix=/usr` to make sure things are installed in the right places
 3) modify "conf/50-wacom.conf" according to the forum entry to include "ISD-V4" in the "MatchProduct" line
 4) ran a make/make install, and rebooted.

Before trying this, I simply tried adding "ISD-V4" to 50-wacom.conf in /usr/share/X11/xorg.conf.d and copying over to /etc/X11/xorg.conf.d, and that didn't do anything. I'm thinking, but can't confirm, that we may just need to update our version to match upstream.
