Linux: Swap Mouse Buttons

List Devices

In terminal, type xinput --list to list devices.

Each device has a name and id. For example, i have “Logitech USB Trackball” with id 10. You need the name or id to set its properties.

Command to Swap Buttons

To swap mouse buttons, type this in terminal:

# swap the middle and right button for device 13
xinput --set-button-map 13 1 3 2

# swap the middle and right button for device named Logitech USB Trackball
xinput --set-button-map "Logitech USB Trackball" 3 2 1

Normally, the button numbers in the command line are in order, like this: 1 2 3 ...

• --set-button-map 2 1 3 means you set button 1 to do 2, and button 2 to do 1.
• --set-button-map 1 1 1 means set buttons 1 and 2 and 3 all to do button 1.

Create Startup Script

The id for the input device may change when the machine starts, or if you plug/unplug your USB devices.

Better to use the device name. However, for some devices, the device name is listed twice.

~/ $ xinput --list
⎡ Virtual core pointer                          id=2    [master pointer  (3)]
⎜   ↳ Virtual core XTEST pointer                id=4    [slave  pointer  (2)]
⎜   ↳ Logitech Gaming Mouse G600                id=8    [slave  pointer  (2)]

⎜   ↳ Logitech G700 Laser Mouse                 id=16   [slave  pointer  (2)]
⎣ Virtual core keyboard                         id=3    [master keyboard (2)]
    ↳ Virtual core XTEST keyboard               id=5    [slave  keyboard (3)]
    ↳ Power Button                              id=6    [slave  keyboard (3)]
    ↳ Power Button                              id=7    [slave  keyboard (3)]
    ↳ TrulyErgonomic.com Truly Ergonomic Computer Keyboard      id=13   [slave  keyboard (3)]
    ↳ TrulyErgonomic.com Truly Ergonomic Computer Keyboard      id=14   [slave  keyboard (3)]

You can have a shell script to get the device name and get the id.

Here's sample scripts for my mouses.

#!/bin/sh

# swap middle and right button
CM_STORM_RECON_ID=$(xinput list | grep "Recon" | head -n 1 | sed -r 's/.*id=([0-9]+).*/\1/')
xinput --set-button-map ${CM_STORM_RECON_ID} 1 3 2

〔see CM Storm Recon Mouse〕

#!/bin/sh

# logitech g600
# swap middle and right buttons
G600_ID=$(xinput list | grep "G600" | head -n 1 | sed -r 's/.*id=([0-9]+).*/\1/')
# xinput --set-button-map ${G600_ID} 1 2 3
xinput --set-button-map ${G600_ID} 1 3 2

〔see Logitech G600 Gaming Mouse〕

Save any of the above in a file as ~/.xprofile.

The ~/.xprofile will run when X11 starts.
