            Bug ID: 105896
           Summary: Acceleration profile for trackpoint is reset upon
                    connection of another Pointer
           Product: Wayland
           Version: unspecified
          Hardware: Other
                OS: All
            Status: NEW
          Severity: normal
          Priority: medium
         Component: libinput
          Assignee: wayland-bugs at lists.freedesktop.org
          Reporter: wilderkde at gmail.com

I have a Thinkpad T460s and have set the trackpoint to flat acceleration
profile via an entry in /etc/xorg.d

When I connect an external mouse (also handled by libinput) the acceleration
profile of the Trackpoint is switched to accelerated. Unplugging the mouse does
not revert this and the Trackpoint is kept on an accelerated profile (barely
usable)


Here is a xinput list-prop for the Trackpoint in normal conditions
