Comment 14 for bug 209911

Unfortunately I don't have a Jaunty machine around at the moment (nor any machine to spare). I'll see if I can do something about it.

I solved my problem (in Intrepid) by removing both the xserver-xorg-input-wacom and wacom-tools packages, and compiling the linuxwacom-0.8.2-2-tarball from the Linux Wacom project's website. I configured it with the "--enable-quirk-tablet-rescale" argument, and now it works.

For the record I should state that my tablet is the Wacom Bamboo. I forgot to mention that in my first comment.
Also, I forgot to mention that I got the hint from this thread: http://www.nabble.com/Cursor-stuck-in-the-wrong-screen-in-TwinView-mode-td21686575.html
