My touchpad doesn't work perfectly after upgrade of Ubuntu

I used all the options on my touchpad (two fingers to scroll the page, two fingers to direct-click, etc) and after I updated Ubuntu today, it just stopped. The touchpad works, but only normal click and double click; the other options are somehow no longer available. Before, in Settings, when I went to the touchpad section, there were several options to configure regarding its features, but now when I open it, I see that there is almost nothing, as if there was a setback.

(Some time ago, I had messed up with grub and something similar had happened, but I managed to edit the file and the touchpad was back to normal, but when my PC started up, several codes appeared on the screen instead of the ubuntu welcome screen , but nothing that hindered the use of the notebook. Then today, when I turned on the pc, I saw that the codes were no longer showing, but the Ubuntu welcome screen; and coincidentally my touchpad was not working well either. I assumed it was a grub issue, as it probably should have been modified when upgrading. So I created a live usb to reinstall grub [the touchpad worked perfectly in live usb], and after reinstalling grub, I turned on the pc and nothing changed ).

Please help me! I'm sending a print of how the touchpad part of the settings is doing. And forgive my english too, I don't speak english.

You update from what version to what version? Get your touchpad ID from `xpinput list` and paste the output of `xinput list-props ID`. Also could be useful `cat /proc/bus/input/devices | perl -00 -ne 'print if /touchpad/i'`. Did you found something on `journalctl -p warning`?

@PabloBianchi first, thanks for help me. I edited the post with the information you asked for (I don't know if this is how I should have posted it, I'm new to the forum). The command "cat /proc/bus/input/devices | perl -00 -ne 'print if /touchpad/i'" returned nothing, and the "journalctl -p warning" returned A LOT. How can I show it here? And by the way, I'm on Ubuntu 20.04, and the update was one of the daily updates.

You added the properties of the mouse, and that info doesn't show any touchpad. "managed to edit the file": what file? About journalctll: You should read it for suspicious warnings/errors. Also [read upgrade package history](https://askubuntu.com/a/116067/349837). Try also booting with a live distro, if that way everything works.

@PabloBianchi That's the problem: it's recognizing it as a mouse by the looks of it! I'm not using any mouse, just the touchpad. And the file I talked about was "grub", but it doesn't seem to be a grub problem now. And yes, it works perfectly in a live distro!

@PabloBianchi Reading the "journalctl -p warning" I found many things, and I also realized that it's not just the touchpad, my bluetooth is also giving an error! I created a [repository on github](https://github.com/thiagodeev/bugss) to send some prints and also a copy of "journalctl -p warning" in .txt format; the file name is "dump-of-journalctl.txt". Please keep helping me! You're the only one

If on a live distro works fine probably the easiest way is to start from scratch, a fresh install

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.
