Scrolling on touchpad too fast, property 'Synaptics Scrolling Distance' doesn't exist

The scrolling of my touchpad is too fast, and I tried using this solution here (as there is no setting for changing the scrollspeed, for some reason)

I've installed the Synapsis driver using this command: sudo apt install xserver-xorg-input-synaptics and then used xinput list to list the devices. It looks like this:

⎡ Virtual core pointer                      id=2    [master pointer  (3)]
⎜   ↳ Virtual core XTEST pointer                id=4    [slave  pointer  (2)]
⎜   ↳ SYNAPTICS Synaptics Touch Digitizer V04 Mouse id=9    [slave  pointer  (2)]
⎜   ↳ SYNAPTICS Synaptics Touch Digitizer V04   id=10   [slave  pointer  (2)]
⎜   ↳ Wacom ISDv4 EC Pen stylus                 id=12   [slave  pointer  (2)]
⎜   ↳ Synaptics TM3075-002                      id=15   [slave  pointer  (2)]
⎜   ↳ TPPS/2 IBM TrackPoint                     id=16   [slave  pointer  (2)]
⎜   ↳ Wacom ISDv4 EC Pen eraser                 id=17   [slave  pointer  (2)]
⎣ Virtual core keyboard                     id=3    [master keyboard (2)]
    ↳ Virtual core XTEST keyboard               id=5    [slave  keyboard (3)]
    ↳ Power Button                              id=6    [slave  keyboard (3)]
    ↳ Video Bus                                 id=7    [slave  keyboard (3)]
    ↳ Power Button                              id=8    [slave  keyboard (3)]
    ↳ Integrated Camera: Integrated C           id=11   [slave  keyboard (3)]
    ↳ AT Translated Set 2 keyboard              id=13   [slave  keyboard (3)]
    ↳ ThinkPad Extra Buttons                    id=14   [slave  keyboard (3)]
    ↳ L U F T H Ü L S E N (AVRCP)               id=18   [slave  keyboard (3)]

My Touchpad is the ID 9, I'm pretty sure. Then I tried to configure the scrolling setting using this command: xinput --set-prop 9 'Synaptics Scrolling Distance' 8 8 It returned the following errror: property 'Synaptics Scrolling Distance' doesn't exist, you need to specify its type and format even tho this property should exist! I then tried something else, another user suggested: xinput --set-prop 9 "libinput Scrolling Pixel Distance" 10 and that returned nothing, and did nothing. When I tried inputting: xinput --set-prop 9 "libinput Scrolling Pixel Distance" 1 it returned the following error:

X Error of failed request:  BadValue (integer parameter out of range for operation)
  Major opcode of failed request:  131 (XInputExtension)
  Minor opcode of failed request:  57 ()
  Value in failed request:  0x153
  Serial number of failed request:  21
  Current serial number in output stream:  22

I then tried writing changes to /etc/X11/xinit/xinputrc which also did not work.

Anybody know how to fix this?

Ubuntu 22.04 is using `libinput`, not `synaptics`. And the `9` id is your mouse. You can check what properies are there by `xinput list-props 9`

I tried changing "libinput Scrolling Pixel Distance" to something lower, but everything is the same (way too fast). How do I fix this?

I also tried changing it to something higher, but that had no effect either.

Okay I've figured out how to do this. you just go into the terminal and do this: synclient VertScrollDelta=-100 and that makes it a lot better.

To make the movement act like a rusty fidget spinner, you change: synclient CoastingFriction=35 (The lower, the more oiled)

But doing that messes up the native settings for the touchpad, and it is now way too fast. You can fix this by doing this to the terminal: synclient MinSpeed=0.05 followed by: synclient MaxSpeed=0.7 make sure to play around with the values to your liking!

Edit: I've realised that all the settings get reset once the computer is restarted.

"all the settings get reset once the computer is restarted" — I bet there is a file somewhere where these parameters could be persisted. I might even try to use `grep -r` to find which file(s) could be identified as candidates...

Did you find the location of the file? @Levente

No sorry, I did not attempt. I meant it as suggesting you try it.

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
