Setting up

  1. 2. Installing Xinput

    Now to Install Xinput Utility for Ubuntu
    Simply play:

    sudo apt install xinput

    Authenticate with the User Admin Pass.
    If Got “User is Not in Sudoers file” then see: How to Enable sudo.

  2. 3. Finding out Device Name

    So to Display Devices List
    Run:

    xinput list

    Select & Copy Device’s Name with Ctrl+x.

    Or simply take note of the Device’s ID.
    But if No Device Name but “xwayland” on GNOME Wayland then instead follow the linked Guide:

    Wayland xinput output

  3. 4. Swapping Mouse Buttons

    Now to Remap Mouse Buttons Map on Ubuntu
    First, to list the Current Map run:

    xinput --get-button-map [DEVICEIDNAME]

    You can use either the Device ID or Name.
    So as in this example:

    xinput --get-button-map 13

    Now for instance to Switch Buttons 1 and 3 simply play:

    xinput --set-button-map 13 3 2 1

    So it’s enough to input the part of the sequence that you intend to Change, but Starting from the head!
    Next to Check your new Setup again:

    xinput --get-button-map 13
    buttons map

  4. 5. Making Permanent Config

    Last, to make a Permanent Xinput Configuration File
    For a Single User using the nano editor, put your both Commands into:

    nano ~/.xsessionrc

    Ctrl+x to Save & Exit from nano Editor.
    So the setup should be consistent also after Reboot.

    xsessionrc setup
