I was a Windows user until very recently, when I decided to switch to some Linux distribution as my daily driver. I chose Zorin OS 16 Pro, primarily because – (1) it is based on Ubuntu, which I have been using on my Raspberry Pi 4 for a while (2) it comes with pre-installed apps (which saved me a couple of hours). The only reason I reluctant to switch because Linux does not support Adobe CC out of the box and it does not support Logitech Options.
MX Master 3 is one of my prized possessions, it is very close to my heart. It is one of the finest mice that I’ve ever had, and it feels really nice. Although I do not use all the MX Master 3 buttons and gestures, I still wanted to be able to configure SmartShift and DPI. Fortunately, LogiOps functions more or less like Logitech Options, albeit all on command line.
Installing LogiOps
Fire your terminal (of course) install dependencies
sudo apt install cmake libevdev-dev libudev-dev libconfig++-dev After this, you need to clone the LogiOps GitHub repo
git clone https://github.com/PixlOne/logiops.gitNext, you need to build the source. You can refer to this link for that.
Once you’re done with building the project, to install, run
sudo make installEnable and start the daemon by running the following command
sudo systemctl enable --now logidYou should be able to run logid by running
sudo logidThe output should look something like this:
[WARN] Error adding device /dev/hidraw2: std::exception [INFO] Detected receiver at /dev/hidraw1 [WARN] Error adding device /dev/hidraw5: std::exception [INFO] Detected receiver at /dev/hidraw4 [WARN] Error adding device /dev/hidraw4: No DJ reports [INFO] Device found: Wireless Mouse MX Master 3 on /dev/hidraw1:1
Configuring
The configuration file resides in – /etc/logid.cfg. If it does not exist, you can simply create it by touch logid.cfg.
Open the logid.cfg and paste the contents from this GitHub Gist.
// Logiops (Linux driver) configuration for Logitech MX Master 3.
// Includes gestures, smartshift, DPI.
// Tested on logid v0.2.3 - GNOME 3.38.4 on Zorin OS 16 Pro
// What's working:
// 1. Window snapping using Gesture button (Thumb)
// 2. Forward Back Buttons
// 3. Top button (Ratchet-Free wheel)
// What's not working:
// 1. Thumb scroll (H-scroll)
// 2. Scroll button
// File location: /etc/logid.cfg

This configuration will set the DPI to 1500 and SmartShift sensitivity to 15.

Conclusion
There are two things that won’t work with this logid.cfg:
- The thumb scroll wheel (useful for switching between tabs)
- Scroll press (I personally use it to emulate
Ctrl + Bin VS Code)
It would be nice to have Logitech Options on Linux since the product information shows that it is ‘compatible’ with Linux, Windows, and Mac. Logitech Options lets you choose app-specific settings which is something that I miss very much, but while developers at Logitech work on Logitech Options for Linux (hoping that they are) LogiOps is the best tool we have to configure most of its functionality.
Issue ‘Forward/Back Button Not Working in VSCode’:
If your Logiop configuration is not working in VSCode, please follow these steps:
- Open your
logid.cfgfile (it will be located at/etc/logid.cfgif you have followed my tutorial). - Navigate to the desired section (forward button and back button have
cid: 0x56;andcid: 0x53;respectively). - Change the ‘type’ from Gesture to Keypress.
- Bind desired keys to it (for event codes, look here).
- Open VSCode and go to Keyboard Shortcuts (Ctrl + K Ctrl + S).
- Bind your favourite action to the keys.
For example, if I want to bind Toggle Tabs to Back Button, I will change:
gestures: (
{
direction: "None";
mode: "OnRelease";
action = {
type: "Keypress";
keys: [ "KEY_BACK" ];
}
}
);
};to
action = {
type: "Keypress";
keys: [ "KEY_LEFTCTRL", "KEY_PAGEDOWN" ];
};Thanks to Eduardo for pointing it out.
You can achieve the same using VSCode Key Bindings, as suggested by Vladimir:
- Using the VSCode Settings (UI), find the โGo Backโ action in the ‘Shortcuts’ settings
- Click on โAdd Keybindingโ
- Click the ‘back’ button on the mouse
- Repeat the steps for the ‘forward’ button
Snap minimize or maximize window below cursor:
The default snap behaviour controls only the active window, i.e., the window which is selected (clicked upon). This may not be ideal since one has to activate the window before operating on it. Thanks to pLum0 ([email protected]), we can make a script using xdotool to fix this.

Fix horizontal scrolling
In case you are facing issues with horizontal scroll (thumb scroll), you may try this fix by Joren Miner ([email protected]). Place the snippet below on the same level as โsmartshiftโ or โhiresscrollโ:
thumbwheel: {
divert: false;
invert: false;
};
