Like any other module: Add (load-module "wacom") somewhere in your .stumpwmrc.
Focus the frame you want to use your wacom tablet. Run map-wacom-to-current-frame.
One thing that can’t be detected is the physical orientation of your device. Even if we could detect landscape/portrait mode, we can’t know which way is right-side-up.
There are a couple of parameters defined in wacom.lisp that you can edit to match the layout of your
tablet on your desk.
(defparameter *portrait-rotate* "ccw"
"If you notice the directions are the reverse of what you desirte when your
frame is in portrait orientation, then change this parameter to 'cw'.")
(defparameter *landscape-rotate* "half"
"If you notice directions are the reverse of what you desire when your
frame is in landscape orientation, then change this parameter to 'none'.")
