The #31 does work for me on a HP tm2 laptop. Anton, perhaps you could
use "uname -r" and " dpkg -s linux-image-3.5.0-16-generic" to verify
that you are running the right kernel with package version
3.5.0-16.25~lp1033783v1 ?

Off the top of my head: I think that the changes to utouch-grail and
utouch-frame have been committed to trunk, so they are probably in

advantage of it) ever got applied.

Here's an xinput test recording. What strikes me as odd is that there
are motion events with only an a[0] coordinate, and no a[1] coordinate.
This seems related.
As far as I can interpret the wacom-pen2.record, it also seems odd that

This trivial patch to xournal is a workaround. The surrounding code (a
function called 'fix_xinput_coordinates') suggests that this bug has

Xournal's workaround fail.
