How to get smooth scroll with Logitech mouse

I have a Logitech M600 mouse working in Ubuntu 20.04. I would like to have smooth scrolling instead of "discrete scrolling", i.e. the same type of scrolling I have in my touchpad. How can I do this? Note that I am not talking about changing the acceleration, the speed, the inertia, etc.

It does not seem like a hot topic, but in case someone (myself in the future?) wants to get smooth scroll with Logitech in Ubuntu, I was able to make it work following this. Summary:

  1. Install Solaar. You need Solaar to access your mouse and change its configuration, in case it does not have "precision scroll" enabled by default (as was in my case).

  2. Run Solaar and enable Scroll Wheel High Resolution enter image description here

  3. Now your mouse will scroll incredibly fast. To fix this create a file in /etc/udev/hwdb.d/71-logitech-mice.hwdb with the following content:

mouse:*:name:*M600*:
    MOUSE_WHEEL_CLICK_ANGLE=1
    MOUSE_WHEEL_CLICK_COUNT=360

Note that the first line is related to the name of your mouse, which you can find using the xinput command. I don't exactly know the syntax, the * are there probably to match any name with this structure. I just put this and it worked. You can customize these numbers, in my case I changed the 360 by 222 which resulted in a better scrolling.

  1. Run
sudo systemd-hwdb update
sudo udevadm trigger /dev/input/event*

and voilà.

This was restart persistent for me, i.e. after restarting my PC it was still working. However, it is not mouse power off and on again persistent, i.e. after you power off the mouse the scroll is not nice. To get it back just run Solaar.

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.
