Tapping lower-right corner of touchpad causes a right-click

Bug Description

I have tapping set off in touchpad settings. Despite this, it seems that tapping the lower right corner of the touchpad does a right-click. The bug happens in multiple machines, but is a bit unreliable to trigger: maybe it requires some exact spot, tapping length, or tapping force on the touchpad to happen.

I can disable Tap touchpad to click, it works only for left-click behavior, but not to right-click behavior.

This still happens with ppa:xubuntu-dev/xfce-4.12

As of now disabling tap to click does not affect the corner button actions.

$ synclient -l | grep -i cornerbutton
    RTCornerButton = 2
    RBCornerButton = 3
    LTCornerButton = 0
    LBCornerButton = 0

I have uploaded a patched version to https://launchpad.net/~thad-fisch/+archive/test for testing purpose. You will have to restart your session and maybe toggle the Tap to Click option once to apply the new settings.

The attachment "set-corner-button-actions.patch" seems to be a patch. If it isn't, please remove the "patch" flag from the attachment, remove the "patch" tag, and if you are a member of the ~ubuntu-reviewers, unsubscribe the team.

I'm unable to reproduce this error. Maybe someone fixed it in the upstream?

I can confirm this is still an issue.

I'm using a Lenovo W550s, fairly recent install of Xubuntu 15.04 (see attached ubuntu-bug output).

The xfconf pointers xml file had explicit values for these options in the synaptics tap action property, which presumably were copied from some initial configuration, but I can't track down the origin of those values (RT=2, RB=3).

Strangely, it appears xserver-xorg-input-synaptics disables corner tapping by default, and xfce4-settings never touches the value, so arguably this bug isn't really xfce4-settings' fault, but I really don't know who else to blame ;-)

And while we're on the topic, I suppose the tap and drag gesture should probably also be disabled when disabling tap click?
