Adjust mouse scroll speed

Hi folks, may I ask a stupid question?

where can I find the settings for my mouse to adjust the mouse wheel scroll “speed”

I found the mouse settings but nowhere i can find how many lines or pixel or whatever value to adjust.

could someone guide me?

I’ve never done this.
But have a look at the last section ‘Device Properties’ here

A brief try with my Mouse
xinput list-props "Microsoft Microsoft 3-Button Mouse with IntelliEye(TM)"
produces a neat list of properties for this specific device.
So perhaps you can explore from there.

thanks for that, will check if I can find something.

I am curious if you have found a solution for this problem! Could you please answer?
My default mouse scrolling speed inside Firefox browser is about half the speed I would like to have and I am looking for a global (XFCE) solution on this.

Ideally I would like to make the mousewheel click trigger exactly like on Windows 7, namely letting you adjust the scroll speed by moving the mouse further up or down.

EDIT: as already pointed out this seems to be configurable via xinput (see last section)

EDIT2: I found a workaround to get the mousewheel click activating fast scrolling, source:

xinput list to get the device ID
xinput list-props ID to start exploring the options you can set
xinput list-props ID > ~/DeviceIDConfigBackup.txt to backup the config to your home folder for a specific device (not really needed but prevention is better than care)

xinput set-prop ID "libinput Scroll Method Enabled" 0, 0, 1 to turn on scrolling via mouse wheel button
xinput set-prop ID "libinput Scroll Method Enabled" 0, 0, 0 to turn off scrolling via mouse wheel button

EDIT3: How I added this as a rule on startup via GUIs so changes are permanent: I did this the first time but it worked. Open xfce4-session-settings, click “Automatically Started Applications” (in your locale) and click the “Add” button. Fill in name, description, the actual command “xinput … 0,0,1” and choose the default “on login” and press “OK”.
