Comment 45 for bug 1414930

Running openSUSE Tumbleweed with latest updates and having installed the Physical Buttons TrackPad/TouchPad on T440s. Tried many options, none work, incl. modifying /etc/X11/xorg.conf.d/files and using psmouse in imps and bare.

Here is some data that might help.

        Synaptics Capabilities (300): 1, 0, 0, 1, 1, 1, 1

me@linux-oi3d:~> xinput list-props "TPPS/2 IBM TrackPoint" | grep Capabilities
no output, unlike Synaptic touchpad

--------------------------

Physical buttons generate events as BTN_0 and BTN_1 for Left and Right, for the SynPS/2 Touchpad and not the TPPS/2 TrackPoint; Middle Button is dead.
