Recently, 2-finger scroll stopped working on my laptop. There may have been some minor updates applied beforehand, but nothing that had to do specifically with pointing devices. This is on a fairly fresh installation of Ubuntu as I was having unrelated issues and decided to start over with a clean slate. In the process of trying to fix the scrolling problem, I noticed that within Settings > Mouse & Touchpad, there are no mousepad-specific options like I know there were previously (I don't remember exactly what they said, I think I could pick between editing settings for my mouse and for my touchpad).
I've tried the commands listed below, but the issue persists.
sudo apt remove gnome-control-center
sudo apt-get install gnome-control-center
I've also followed the answers to a very similar question here: Mouse & Touchpad Separate Settings Missing. However, none of these worked either, and as it was both several years and several versions of Ubuntu ago, maybe some things have changed. If anyone has a solution to the overarching 2-finger scroll issue, that would be greatly appreciated as well.
I've listed the output of xinput and xinput list-props 19 below. The touchpad is ELAN0406:00 04F3:30A6 Mouse at ID 19.
