On a Linux-based dual screen/monitor/display setup, swap your mouse pointer from one screen to the other instantly.

• Dual screens/monitors/displays
• xdotool installed
• Tested working on Ubuntu 20.04 (Gnome Desktop), but probably works on many others.

1. Install xdotool if you dont have it

   sudo apt install xdotool
   

2. Download and open screen-swap.sh in a text editor and change the settings to match your screen setup.

   To find your screen values:

   xrandr | grep " connected"
   

   Take note of the widthxheight+X+Y values (e.g. 3840x2160+0+0) for both connected screens Then edit the script with these values

   nano screen-swap.sh
   

3. Make the script executable if required

   chmod +x swap-screen.sh
   

4. Copy the script to somewhere on your path

   cp swap-screen.sh ~/.local/bin/
   

5. Test by running swap-screen.sh, then bind this command to a hot-key or mouse button. For example I bind it to an extra side-button on my mouse using Keyboard Shortcuts settings in Ubuntu Gnome Desktop.

Suggestions/PRs welcome.

• Make the script auto-detect monitor dimensions
