Touchpad scroll speed is much too fast on my HP Omnibook using Zorin 18.1 Pro. Please add the ability to modify the scroll speed. Thanks.
Welcome to the Forum!
When You go to Settings>Mouse and Touchpad do You haven't there an Option for Scroll Speed?
Until that feature will be available, you could try this if you are running on Wayland:
To install the tool enter in terminal
version="0.3.3"
curl -LO "https://github.com/daniel-g-carrasco/wayland-scroll-factor/releases/download/v${version}/wayland-scroll-factor_${version}-1_amd64.deb"
sudo apt install "./wayland-scroll-factor_${version}-1_amd64.deb"
After the installation you find it at start menu named "Wayland Scroll Factor". There you can make your settings and slow down the scroll speed.
I tested it today and it worked when I reduced the vertical scroll to <1, e.g. 0,2, enabled the slider for gnome preload and then logged out.
The .deb file is created at home directory (~). Save the file at a place where you find it if you want to uninstall the program.
It's a gnome problem. The issues has been open for 7 years already.
and
maybe they would fix in another 7 years but it's gnome, don't expect soon. GNOME is known for its "GNOME knows best" philosophy.
