Logitech MX Master

Usage

The mouse should work with no special configuration if using the unified receiver USB dongle. Plug in the dongle, then press the connect button on the mouse.

To use Bluetooth, change the channel on the bottom of the mouse, and click the connect button. Now, search for the mouse with a bluetooth manager of your choice and pair. In future it should connect as soon as you switch to that channel when your bluetooth is active. If you have problems with the mouse not showing when scanning, see Bluetooth LE device does not show up in scan

The mouse exists in 3 versions:

  • Mx Master.
  • Mx Master 2s.
  • Mx Master 3.

The functionalities are the same.

Mappings for extra buttons

Installing #Logiops logiops-gitAUR it is possible to acquire everything this mouse has to offer:

  • Easy programmable buttons.
  • DPI selection.
  • Smartshift (hyperfast and click-to-click wheel mode).
  • HiresScroll.
  • Gestures.

It is possible to use just #Xbindkeys and tweak the desktop shortcuts to obtain some customization, but with some caveats (look notes below).

Logiops

It can be executed as application via command line by running

# logid

Or as a service by systemd.

# systemctl start logid

The configuration lives in /etc/logid.cfg. But the package comes with no configuration. One needs to create this specifying the name of the device to be used. To obtain that name launching from cli

# logid -v

The name of the detected device is printed.

Then you can create the configuration file.

Examples

See the configuration format documentation for more detail, including the list of CIDs (button codes) and the list of key codes.

This minimal configuration file simply makes each button work as a normal mouse button, ignoring gestures. It will allow the extra buttons to be used normally, such as in games and by Xbindkeys (see below).

/etc/logid.cfg
devices: ({
  name: "Logitech Wireless Mouse MX Master 3";

  // A lower threshold number makes the wheel switch to free-spin mode
  // quicker when scrolling fast.
  smartshift: { on: true; threshold: 20; };

  hiresscroll: { hires: false; invert: false; target: false; };

  // Higher numbers make the mouse more sensitive (cursor moves faster),
  // 4000 max for MX Master 3.
  dpi: 1500;

  buttons: (

    // Make thumb button 10.
    { cid: 0xc3; action = { type: "Keypress"; keys: ["BTN_FORWARD"]; }; },

    // Make top button 11.
    { cid: 0xc4; action = { type: "Keypress"; keys: ["BTN_BACK"];    }; }

  );
});

Xbindkeys

List of events sent by mouse:

Physical action detected as With minimal logid
config above
Left button button 1 button 1
Press to wheel button 2 button 2
Right button button 3 button 3
Scroll wheel up button 4 button 4
Scroll wheel down button 5 button 5
Scroll hor_wheel right (up) button 6 button 6
Scroll hor_wheel left (down) button 7 button 7
Side-bottom button button 8 button 8
Side-top button button 9 button 9
Thumb button Ctrl+Alt+Tab button 10
Press "i" button under wheel Not detected by xbindkeys button 11

Notes:

  • It is impossible to move mouse cursor while thumb button is pressed, but possible to use any other actions (pressing buttons and scrolling wheels). Ctrl+Alt+Tab event is sent only after releasing thumb button. Using logid to reassign this button removes this limitation.
  • If you wish, you can get experience of thumb button like in Windows or Mac. In kde go to System settings → Shortcuts → Global Shortcuts → KWin → Show all windows from all desktops. It is set to ctrl+f10 by default. Set ctrl+alt+tab for this action and apply settings.
  • "I" button under wheel is undetectable in Linux by default, but works as switching wheel between free and rattle mode. With logid it can be reassigned for use.
  • Logitech gestures (moving mouse up/down/left/right while thumb pressed) are not detected in Linux, but are implemented in software by logid.

The vertical wheel and the two buttons near it should work right away, however the thumb button requires some special treatment, and you might want to remap the rest.

To remap the buttons of the mouse you can use the packages xbindkeys and xautomation.

xbindkeys will redirect the buttons and xte (which is included in xautomation) will execute the custom key presses. To do so, create a config file named .xbindkeysrc in your home directory.

Here is a sample configuration for the vertical scroll wheel and the two buttons near it:

# thumb wheel up => increase volume and unmute      
"amixer -D pulse set Master 4000+ unmute"
   b:6                                   
                                        
# thumb wheel down => lower volume       
"amixer -D pulse set Master 4000-"       
   b:7                                   
                                        
# backward button => previous song       
"xte 'key XF86AudioPrev'"                
   b:8                                   
                                        
# forward button => next song            
"xte 'key XF86AudioNext'"                
   b:9

If using PulseAudio (more info here):

# thumb wheel up => increase volume
"pactl set-sink-volume @DEFAULT_SINK@ +2%"
   b:6

# thumb wheel down => lower volume
"pactl set-sink-volume @DEFAULT_SINK@ -2%"
   b:7

If you prefer to get a visual feedback on how the volume level changes you could use the following lines instead (Tested in GNOME and KDE)

# thumb wheel up => increase volume
"xte 'key XF86AudioRaiseVolume'"
   b:6

# thumb wheel down => lower volume
"xte 'key XF86AudioLowerVolume'"
   b:7


Now start xbindkeys, preferably add that to the autostart list of your desktop environment.

The thumb button is special. With the Logitech software available for Windows and Mac, you would be able to map up to 5 actions to it: by pressing the button or by pressing the button and moving the mouse in one of four directions. As of November 2015, there is no way to enable the direction feature using Arch.

If you look at the keys the button triggers you will notice that it sends a series of keys, confusing xbindkeys. You need to add a short sleep here so xbindkeys will only react on the first keys send so we can at least map one action to it:

# thumb button => play/pause music         
# Credit to gregmuellegger https://bbs.archlinux.org/viewtopic.php?pid=1551271#p1551271                               
# We need a sleep here since the button triggers a few more key codes. 
# It also triggers Control+Mod2+Control_L and Alt+Mod2+Alt_L. The sleep       
# prevents that X receives those keypresses simultaniously. Therefore they    
# might interfere and trigger unwanted actions. By the sleep we make sure that
# the Alt+Left is receive as distinct event.                                  
"sleep 0.1 && xte 'key XF86AudioPlay'"                                        
   m:0xc + c:23

Remember that all changes to ~/.xbindkeysrc require a restart of the xbindkeys process:

$ pkill xbindkeys && xbindkeys

Power

Battery status can be read as described on Logitech Unifying Receiver. e.g. Solaar (solaar) has a system tray utility.

Smart shift

Smart shift is where the scroll wheel switches from click-to-click to smooth scrolling automatically, based on the speed at which it is being spun.

Logiops

Any mouse button can be assigned to switch between modes. The default settings are with the smart-shift threshold around 20 and the top button (just below the wheel) used to toggle between always-smooth and smart-shift (clicky when scrolling slowly only). Increasing the threshold number requires the wheel to be spun faster before it will switch into smooth-scrolling mode.

To reproduce the default settings, use this snippet in the config file as shown above:

/etc/logid.cfg
...
  smartshift: { on: true; threshold: 20; };
  buttons: (
    // Make top button (0xc4) switch modes
    { cid: 0xc4; action = { type = "ToggleSmartshift"; }; },
...

Change the threshold or use a different button (cid) as needed.

Solaar

Instead of logid, Solaar can also be used to change the sensitivity of changing the mouse wheel mode (between hyperfast and click-to-click), install solaar. A slider appears that can be set somewhere between 0 and 50 (inclusive). 0 means always in hyperfast mode, 50 means always in click-to-click mode.

To change the sensitivity, change this value somewhere between 0 and 50.
