Description Olivier Fourdan 2009-05-08 16:59:06 UTC 
Description of problem:

The driver for Wacom tablet in the kernel does not report the stylus button being pressed after a proximity leave/re-enter event for Intuos tablets.

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

kernel-2.6.18-128.1.6

How reproducible:

100% reproducible

Steps to Reproduce:
1) Install and configure a Wacom Intuos tablet on EL5
2) Press and hold a button on the stylus
3) Move away from button while still holding down the stylus
4) Move back into the button coordinates while still holding down stylus
  
Actual results:

The button does not retain the button-pressed event on moving back into focus

Expected results:

Button should retain button-pressed event on moving back into focus.

Additional info:

The upstream maintainer of the Wacom driver (Ping Cheng <pingc>) has identified the portion of code missing in the driver we are shipping in EL5 and provided a patch to the customer.

The patch adds a portion of code that is present in the driver upstream,in wacom_intuos_inout() in wacom_wac.c:

http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git;a=blob;f=drivers/input/tablet/wacom_wac.c

A test kernel including that patch has been provided to the customer who confirmed that it fixes the issue.
Comment 2 Günther Sommer 2009-05-11 11:46:56 UTC 
This was related to a WACOM Cintiq 21UX tablet. As the WACOM Intous and the Cintiq share the same driver, they are both affecteed.

We did test the kernel-2.6.18-156.el5 and the proximity problem is solved in there as well.
