Increase Trackpoint Sensititvity with SystemD (Ubuntu 15.04 or later)

  • 772

My upstart job which configured my trackpoint sensitivity (Values 255, 255) does not work anymore. How can I get equivalent behaviour with systemd?

  1. Best Answer
    1. Ctrl + Alt + T (Opens Terminal)
    2. sudo -i gedit /etc/tmpfiles.d/tpoint.conf

    3. Add the following lines (*):

      w /sys/devices/platform/i8042/serio1/speed - - - - 255
w /sys/devices/platform/i8042/serio1/sensitivity - - - - 255
w /sys/devices/platform/i8042/serio1/inertia - - - - 6
w /sys/devices/platform/i8042/serio1/press_to_select - - - - 0

    4. Adjust the numbers to your liking. Higher = More Fast/Sensitive -- press_to_select is for tapping on the trackpoint to simulate a click. 1 to enable.

    5. Save, Exit.

    6. For these changes to take effect before next reboot (see), run

    sudo systemd-tmpfiles --prefix=/sys --create

    (*) Thinkpad X1 Yoga Or Thinkpad W530 users will need to modify slightly:

    w /sys/devices/platform/i8042/serio1/serio2/...

    You can find out the exact path on your device via:

    find /sys/devices/platform/i8042 -name name | xargs grep -Fl TrackPoint | sed 's/\/input\/input[0-9]*\/name$//'

    Personal Recommendation

    • Use the highest settings (255,255)
    • Go into Mouse and Touchpad settings and set that bar value to the lowest value.

    After you get used to it, your finger will have to do much less effort into moving the cursor and will greatly reduce any strains or pains in your finger.

  2. For Thinkpads circa 2019, ( I have a Thinkpad x390 Yoga ) -- the following solution worked for me:

    1. Find the device name: TPPS/2 Elan TrackPoint by running:
    xinput --list --short

⎡ Virtual core pointer                          id=2    [master pointer  (3)]
⎜   ↳ Virtual core XTEST pointer                id=4    [slave  pointer  (2)]
⎜   ↳ Wacom Pen and multitouch sensor Finger touch      id=9    [slave  pointer  (2)]
⎜   ↳ Wacom Pen and multitouch sensor Pen stylus        id=10   [slave  pointer  (2)]
⎜   ↳ SynPS/2 Synaptics TouchPad                id=14   [slave  pointer  (2)]
⎜   ↳ TPPS/2 Elan TrackPoint                    id=15   [slave  pointer  (2)]
⎜   ↳ Wacom Pen and multitouch sensor Pen eraser        id=17   [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)]
    ↳ Sleep Button                              id=8    [slave  keyboard (3)]
    ↳ Integrated Camera: Integrated C           id=11   [slave  keyboard (3)]
    ↳ Integrated Camera: Integrated I           id=12   [slave  keyboard (3)]
    ↳ AT Translated Set 2 keyboard              id=13   [slave  keyboard (3)]
    ↳ ThinkPad Extra Buttons                    id=16   [slave  keyboard (3)]
    ↳ Apple, Inc. USB-C to 3.5mm Headphone Jack Adapter id=18   [slave  keyboard (3)]
    1. set the sensitivity to max with this command:
    xinput --set-prop "TPPS/2 Elan TrackPoint" "Coordinate Transformation Matrix" 1 0 0 0 1 0 0 0 1

    You can use 0.5 if you want to halve it. Most of those 0's have to do with direction.

    1. Go to your mouse settings and do something like this:

    enter image description here

    And that has given me the best sensitivity thus far.
