Description Fabio Alessandro Locati 2014-08-12 21:13:59 UTC
Description of problem:
The buttons are "read" as part of the touchpad, so if I hold a finger on the left button (without pressing it) and move another finger on the touchpad itself, RHEL7 interpenetrates it as a two finger scroll. This is the wrong behavior, because it should not consider the buttons area as an active touchpad area. On Fedora 20 this problem does _NOT_ occurs.

Version-Release number of selected component (if applicable):
kernel.x86_64                   3.10.0-123.6.3.el7          @rhel-7-desktop-rpms
xorg-x11-drv-synaptics.x86_64   1.7.1-10.el7_0.1            @rhel-7-desktop-rpms

On bug #1048314 there is some talk about problems on the same touchpad on different kernel versions, so it could end up being more a kernel problem than a driver problem.

Apologies for the delay, this one slipped through. Please record your device with evemu-record when it emits this behaviour and attach the recording here. This will make it possible for us to re-play the recording and check what's going on here.

Unfortunately, we have to close this bug as INSUFFICIENT_DATA after over 6 months in needinfo state. If this is still an issue, please re-open the bug and provide the requested data. Please make sure you first test with a fully up-to-date RHEL 7 before re-opening though.
