my Wacom Graphire 4 used to work perfectly well until, I think, Ubuntu 10.4. At that point something changed in the configuration and I couldn't assign a key to the scroll wheel anymore (note: the pad's scroll wheel, not the mouse's), i.e this command:
xsetwacom set "Wacom Graphire4 6x8 pad" AbsWDn "key +"
returns silently without error but nothing happens. Same goes for
Apparently though the problem is even deeper as pressing the wheel in a
xev window doesn't seem to have any effect.
Moreover I am thoroughly confused on how the various pieces (kernel driver, xorg driver, evdev, HAL, xinput?) are supposed to work together and if the
wacom module that ships with Ubuntu is the one from linuxwacom or not.
Any ideas? I don't want to become an X.org hacker just to understand what's going on... it used to work!
NOTE: I have already read question 3940, but that's not the same problem.
