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? ** Attachment added: "ubuntu-bug-xfce4-settings-synaptics-corner-tapping.txt" https://bugs.launchpad.net/ubuntu/+source/xfce4-settings/+bug/1260341/+attachment/4405844/+files/ubuntu-bug-xfce4-settings-synaptics-corner-tapping.txt -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1260341 Title: Tapping lower-right corner of touchpad causes a right-click To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xfce4-settings/+bug/1260341/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
