Comment 18 for bug 556670

Ok,
I found a solution for my case. I hope it works for others.

If you were using the standard xsetwacom.sh script that is given here

When you use xf86-input-wacom-0.11.1
by removing the definition of the buttons I manage it to work properly.
That is the new .xsetwacom.sh in my home folder is just

## stylus = "Wacom Bamboo Craft Pen stylus"
xsetwacom set "Wacom Bamboo Craft Pen stylus" rotate HALF
xsetwacom set "Wacom Bamboo Craft Pen stylus" Suppress "2"
xsetwacom set "Wacom Bamboo Craft Pen stylus" RawSample "4"
xsetwacom set "Wacom Bamboo Craft Pen stylus" Threshold "6"
xsetwacom set "Wacom Bamboo Craft Pen stylus" PressureCurve "5 10 90 95"
xsetwacom set "Wacom Bamboo Craft Pen stylus" Button 4 8

## eraser = "Wacom Bamboo Craft Pen eraser"
xsetwacom set "Wacom Bamboo Craft Pen eraser" rotate HALF

## pad = "Wacom Bamboo Craft Finger touch"
xsetwacom set "Wacom Bamboo Craft Finger touch" rotate HALF

## pad = "Wacom Bamboo Craft Finger pad"
xsetwacom set "Wacom Bamboo Craft Finger pad" rotate HALF

(Note: The rotate HALF commands are because I am left handed).

Good luck
