Touchpad on my laptop does not work. It does work properly in Ubuntu 18.04 but does not after I upgraded to 22.10. I have removed 'xserver-xorg-input-synaptics' and installed it again. That did not help.

Following is information of my laptop.**

1. laptop's environment

os: ubuntu 22.10
kernel release:5.19.0-29-generic
version of touchpad driver: xserver-xorg-input-synaptics  1.9.1-1ubuntu3  amd64  Synaptics TouchPad driver for X.Org server

@David, thanks for your edit to make sense. This issue has been solved today finally. I will post the solution when I was freed from a project.

I sit in a Tesla and translated this thread with Ai:

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
