Description Peter Hutterer 2010-05-20 18:41:13 EDT
Description of problem:
Absolute axes are assigned wrong by the wacom driver. The reason is an extra flag supplied by the driver (OutOfProximity) that's added to the Relative/Absolute setting in the mode field.

Relative and Absolute aren't meant as flags, hence many clients and the server often only have a binary test in the form of 
  if (mode == Relative) else
  if (mode == Absolute) else

With the OutOfProximity flag (0x2) binary OR'd those checks fail, leading to client-implementation dependent interpretation of axis modes.

Version-Release number of selected component (if applicable):

How reproducible:
xinput --list --long | less, then look at the axis mode of stylus, eraser (should be absolute by default)

Additional info:
Patch from upstream, simply remove the invalid OutOfProximity flag.

xorg-x11-drv-wacom-0.10.5-3.el6 is available in brew.
Comment 5 Peter Hutterer 2010-06-09 20:43:09 EDT
Changing component to xorg-x11-server. The underlying cause turned out to be a problem in the protocol parsing code in the server.

xorg-x11-server-1.7.7-7.el6 is available in brew.
