On other ThinkPads I've succesfully configured the trackpoint with udev using this method but on my new Lenovo Thinkpad 13 this isn't possible:This command:find /sys/devices/platform/i8042 -name name | xargs grep -Fl TrackPoint | sed 's/\/input\/input[0-9]*\/name$//'... outputs:/sys/devices/platform/i8042/serio1But neither that folder nor any of the subfolders contain the files sensitivity and speed. Same issue has been confirmed by ThinkPad 13 owner on another kernel and distro.I'm guessing that the kernel driver doesn't properly detect that the device is in fact a trackpoint. This assumption is backed by this (not very informative) hardware evaluation from Ubuntu.An alternative method for configuring the trackpoint is using xinput but as my distro - Debian - har switched to libinput this is a headache of its own due to this bug (that's apparently affecting Fedora, too.)I would really like to be able to configure the trackpoint by way of udev and the method above but I don't know how to debug further.Does Ubuntu's hardware evaluation mean that it's an unsolvable hardware issue?Or is it a kernel bug?How can I know?Some system output:# uname -aLinux debian 4.5.0-2-amd64 #1 SMP Debian 4.5.3-2 (2016-05-08) x86_64 GNU/Linux# xinput listVirtual core pointer                        id=2    [master pointer  (3)]    Virtual core XTEST pointer                id=4    [slave  pointer  (2)]    ETPS/2 Elantech Touchpad                  id=13   [slave  pointer  (2)]    Elantech PS/2 TrackPoint                  id=14   [slave  pointer  (2)] Virtual core keyboard                       id=3    [master keyboard (2)]     Virtual core XTEST keyboard                 id=5    [slave  keyboard (3)]     Power Button                                id=6    [slave  keyboard (3)]     Video Bus                                   id=7    [slave  keyboard (3)]     Power Button                                id=8    [slave  keyboard (3)]     Sleep Button                                id=9    [slave  keyboard (3)]     Integrated Camera                           id=11   [slave  keyboard (3)]     AT Translated Set 2 keyboard                id=12   [slave  keyboard (3)]     ThinkPad Extra Buttons                      id=15   [slave  keyboard (3)]# xinput list-props 14Device 'Elantech PS/2 TrackPoint':    Device Enabled (136):   1    Coordinate Transformation Matrix (138): 1.000000, 0.000000, 0.000000, 0.000000, 1.000000, 0.000000, 0.000000, 0.000000, 1.000000    libinput Accel Speed (274): 1.000000    libinput Accel Speed Default (275): 0.000000    libinput Accel Profiles Available (276):    1, 1    libinput Accel Profile Enabled (277):   1, 0    libinput Accel Profile Enabled Default (278):   1, 0    libinput Natural Scrolling Enabled (279):   0    libinput Natural Scrolling Enabled Default (280):   0    libinput Send Events Modes Available (258): 1, 0    libinput Send Events Mode Enabled (259):    0, 0    libinput Send Events Mode Enabled Default (260):    0, 0    libinput Left Handed Enabled (281): 0    libinput Left Handed Enabled Default (282): 0    libinput Scroll Methods Available (283):    0, 0, 1    libinput Scroll Method Enabled (284):   0, 0, 1    libinput Scroll Method Enabled Default (285):   0, 0, 1    libinput Button Scrolling Button (286): 2    libinput Button Scrolling Button Default (287): 274    libinput Middle Emulation Enabled (288):    0    libinput Middle Emulation Enabled Default (289):    0    Device Node (261):  /dev/input/event1    Device Product ID (262):    2, 14    libinput Drag Lock Buttons (290):   <no items>    libinput Horizonal Scroll Enabled (263):    1
