Wacom driver with Intuos tablet does not report button press after a proximity leave/re-enter
Last modified: 2013-03-03 21:48:03 EST
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@wacom.com>) 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.
This was related to a WACOM Cintiq 21UX tablet. As the WACOM Intous and the Cintiq share the same driver, they are both affecteed.
