Hi Duncan,

I couldn't attend the UDS but I know that Federico Mena Quintero (at
Novell) was working on this in a separate branch of the
gnome-settings-daemon but he hasn't committed anything upstream yet (I
guess he's focusing on different projects):
http://git.gnome.org/browse/gnome-settings-daemon/log/?h=randr-rotate-wacom-tablet

As Rafi said, this solution also involves setting a gconf key to tell
the daemon whether we want it to rotate input devices or not when
screens are rotated.

Currently Federico's code makes use of the xsetwacom tool instead of
using Xinput (which is what we need). I'm very familiar with the
gnome-settings-daemon code and, if there's enough interest at
Canonical, I'm available to work on it but I don't own any Ntrig
touchscreen and I can't use my Stantum tablet because it doesn't work
with xinput Calibration.

Let me know.

Regards,
