這篇說明的還滿好的，簡單、明瞭，直接實作、除錯、檢測。

Adjust Trackpoint speed on Ubuntu 22.04

 ref: https://askubuntu.com/questions/1432996/adjust-trackpoint-speed-on-lenovo-p70-ubuntu-22-04

Here's what worked for me; your mileage may vary. First, find your device:

$ xinput list
⎡ Virtual core pointer                      id=2    [master pointer  (3)]
⎜   ↳ Virtual core XTEST pointer                id=4    [slave  pointer  (2)]
⎜   ↳ TPPS/2 IBM TrackPoint                     id=12   [slave  pointer  (2)]
⎜   ↳ Synaptics TM3053-004                      id=11   [slave  pointer  (2)]
⎜   ↳ ELAN Touchscreen                          id=9    [slave  pointer  (2)]
...

On my system, I see it as TPPS/2 IBM TrackPoint. Next, find the acceleration property:

$ xinput list-props 'TPPS/2 IBM TrackPoint' | grep Accel
    libinput Accel Speed (342): 0.000000
    libinput Accel Speed Default (343): 0.000000
    libinput Accel Profiles Available (344):    1, 1
    libinput Accel Profile Enabled (345):   1, 0
    libinput Accel Profile Enabled Default (346):   1, 0

Here, I see it as Accel Speed (342), and the 342 is what I need. After some experimentation, I was able to determine that the value, by default 0.000000 is expected to be in the range [-1, 1]. For me, -0.2 ended up being a good speed:

$ xinput set-prop 'TPPS/2 IBM TrackPoint' 342 -0.2

 

 

ubuntu 22.04 disable trackpoint middle button paste

 ref: https://gist.github.com/bumbummen99/fcab50dad5638399375693a70a8c17f4

先執行 

xinput --list

確認 TrackPoint 的 id 是多少，假設是 15，就執行以下指令：

xinput set-button-map 15 1 0 3 4 5 6 7

就可以關掉中鍵貼上的動作了。

Asus 筆電

根據詢問 Asus 的結果，華碩的 ExpertBook 筆電，以我這台 ExpertBook BM2402來看，是確定 SensePoint 不支援 Linux 環境的 ，其他例如藍芽、網路、音效等，也有可能不支援在 Linux 環境下使用！ 

我自己的 BM2402 ，不支援 SensePoint 和 藍芽！
