I couldn't solve this problem despite spending many hours (two days), so I decided to ask here. How can I restore the default settings for the Apple Magic Trackpad 2 when using on Ubuntu?
My problem is the following: I am using Ubuntu 20.04 LTS. After using my Apple Magic Trackpad 2 for some time without major issues, it stopped working. (I am using it via a cable). I always have to click on it very hard to be able to move my cursor. Unusable. I was able to find a kind of a workaround here (Apple Magic Trackpad 2 configuration )
It suggest using a command like
xinput set-prop 17 296 2, 2, 0
With xinput list I first identify the trackpad's id (not persistent!). Now it is 21.
⎜ ↳ Apple Inc. Magic Trackpad 2 id=21 [slave pointer (2)]
These are its properties that I identify by typing xinput watch-props 21.

So far, I haven't modified anything. According to the above mentioned workaround, we now need to identify the 'Synaptics Finger'-ID which is 332 in this case (not persistent either):
xinput set-prop 21 332 2, 2, 0
After that, it seems to work.
However, whenever I restart either the computer or the trackpad, all of the changes disappear. I initially added a shortcut for these commands; however, it is not effective as ids tend to change after unplugging the trackpad. I also considered writing a script, however, it should come into effect whenever I plug in/turn on the trackpad - not when the computer is turned on.
I want to delete all of the settings stored when connecting this trackpad. Just as it was at the beginning. Similar to the following solution for macos.
So far, I've also tried the following commands restoring settings - they weren't effective.
dconf reset -f /
dconf reset -f /org/gnome/desktop/peripherals/mouse/
dconf reset -f /org/gnome/desktop/peripherals/touchpad/
How can I restore the default settings for the Apple Magic Trackpad 2 when using on Ubuntu? Alternatively, how can I make these changes persistent?
Thank you so much for any help!
