There are many methods circulating on the Internet, but they are generally changed through xorg. conf method, while Ubuntu uses xorg. conf. d, xorg. conf settings will be reset by Ubuntu, and thus become invalid. If xorg. conf. d is completely deleted, it may cause adverse effects. In fact, you can directly change the file in xorg. cong. d.

In Linux, the *. conf. d directory is used to declare that every file in this directory is the same as *. conf. So

$ Cd/; find | grep xorg \. conf

Traverse all nodes and search for xorg. conf. Generally, xorg. conf. d. Open each file in this directory, the current xorg. conf. d. Use inputclass when setting input. Locate all MatchIsTouchpad sections and comment out (add the "#" sign before each line) or other methods. Save and exit.
In addition, after a period of research, we found that the Linux kernel supports trackpoint very well and does not need any additional driver. However, you must configure it correctly. For example, you can change the trackpoint sensitivity directly in/sys/devices/platform/i8042/serioX/serioY/sensiti.pdf. (The values of X and Y vary with machines .)
