I've been using Logitech MX master 2s with Ubuntu 18.04 for like a week now and this mouse comes with 2 settings for scrolling one is a click to click scroll like a normal mouse and other is a hyperfast free scroll. if you scroll fast enough the click to click scroll turns to hyper-fast scrolling, which is a really good feature on Windows or Mac you can control the sensitivity of when Click to Click scrolling gets converted to hyperfast free scrolling. I think this is also possible in Ubuntu (or lets say Linux) because it's been demoed on Arch Wiki.

on Arch Wiki it's written and I quote:

Arch Wiki Text

But Solaar on Ubuntu doesn't have that slider

Solaar on Ubuntu

also, note that Solaar hasn't been updated since 2014-04-20. do you have any other way to solve this issue?

  • How did you install Solaar in Ubuntu? – Leo Jul 26 '18 at 09:26
  • You could try out the unofficial driver for logitech mice and keyboard and change the setting for the smartshift threshold in config. The installation and a sample config is here:https://askubuntu.com/a/1246278/678626 – v.tralala Jun 02 '20 at 21:43

first uninstall your current solaar version, then try this:

git clone https://github.com/pwr/Solaar.git
cd Solaar

Update: The following is unnecessary now, as the pull request has been merged:

unfortunately the support for the MX Master 2s seems not to be in there yet, but there's a pull request with the support, so you could do: git pull origin pull/399/head

to download it into your local repository. If it opens an editor just hit save and exit it.

Continue here

Then you can run

sudo python setup.py install
/usr/local/bin/solaar

    The pull request has been merged, there is no more need to pull it. – pim Oct 09 '18 at 13:36
  • The version from the official Ubuntu 18.04 packet repositories does not yet contain the patch. Installing it from the Git repository is necessary but works without a problem. – Lukas Kalbertodt Jun 17 '19 at 10:58
  • I have the MX Master 2S and after I followed the above instructions, I don't get the other options/info at Solarr except for: Battery, Wireless Link... – Alonzzo2 Jun 24 '19 at 14:14
  • I made a mess out of my Ubuntu 20.04. Firstly, I installed python (apt install python) and got Python 2. Then installed Python 3. Then the package pyudev (pip3 install pyudev) and tried some tweaks to the scripts. But, I couldn't pass this error: Solaar: missing required system package python3-pyudev. Luckily, the answer from @Alonzzo2 worked just fine. – Cesar Moore May 22 '20 at 02:10

For those who want to config the smart-shift for MX MASTER 2S (which can't be configured via the UI), Follow Catscrash's solution, then go to Solaar's CLI instead of the GUI, and run the following command:

/usr/local/bin/sudo solaar config 1 smart-shift 30

  • 1 is your device number (run solaar show to see a device list.)

  • 30 is a number between 0-50 (0 is total free scroll).
