Touchpad Sensitivity

I want to change the insanely sensitive default touchpad scroll speed, and tried to follow the instructions here but to no avail, because the synaptics file is completely missing from my x11 folder. Does anyone else have this issue, and how did you solve it? I don't want to install something extra like imwheel, I'd rather edit config files. Thanks!

So you have already done this? About touchpad issues - #2 by Aravisian

I assume you have also played with: Zorin>Settings>Touchpad and Mouse
re sensitivity.

I just installed synaptics (I couldn't find documentation about how to do so until your comment, thanks!), but after editing the config file and restarting, nothing has changed. Here's the edited part of the file:

Section "InputClass"
        Identifier "touchpad catchall"
        Driver "synaptics"
        MatchIsTouchpad "on"
# This option is recommend on all Linux systems using evdev, but cannot be
# enabled by default. See the following link for details:
      MatchDevicePath "/dev/input/event*"

Section "InputClass"
        Identifier "touchpad ignore duplicates"
        MatchIsTouchpad "on"
        MatchOS "Linux"
        MatchDevicePath "/dev/input/mouse*"
        Option "Ignore" "on"
        Option "FingerLow" "30"
	Option "FingerHigh" "30"

Did I edit it wrong?

I have never had the problem myself, I just pointed you to a possible solution that helped others in the past, so I cannot help from personal experience.
Did you hget any configuration errors?
Did you look at the blogspot link (commented out part of your file screenshot above)?
Maybe worth doing a wider websearch using "touchpad sensitivity Ubuntu 22.04" to see other posts on subject.
