Ubuntu 18.04 Swap Mouse Buttons – Step-by-step

Setting up

2. 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.

3. 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:

4. 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

5. 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.
