This mouse feels good to touch. It just feels nice. The scroll wheel, called Magspeed Wheel, feels really good to use with its tactile feeling. However try pressing the black button in the middle – then it changed from Ratchet mode to Freespin mode , basically it flies. You can spin it really, really fast. Awesome.

However, Logitech does not provide its configuration software on Linux. But no worries, we can use LogiOps for that.

Copy-paste these lines to set it up ; these are for Ubuntu 20.04, if you’re using different Linux distro, you might need to change some of it.

sudo apt-get install -y install cmake libevdev-dev libudev-dev libconfig++-dev

cd /tmp ; wget https://github.com/PixlOne/logiops/archive/refs/heads/master.zip ; mkdir tmp ; cd tmp ; unzip ../master.zip ; cd logiops-master ; mkdir build ; cd build

cmake .. ; make ; sudo make install 

sudo nano /etc/logid.cfg

sudo systemctl enable --now logid

You may notice that we’re creating a configuration file name logid.cfg , there’s a [ guide to create it ], however some may find it confusing.

Therefore please find a sample logid.cfg for MX Anywhere 3 below. It will enable a reasonably nice usage of the device, and also enable you to change the mouse’s DPI by pressing the side buttons.

Enjoy.
