This problem has been reported by numerous users, but unfortunately, no remediations have been effective in resolving the issue. In this article, we'll delve into the possible causes and explore potential solutions to help you overcome this persistent problem.

To better understand the issue, let's take a closer look at your system configuration. You have a laptop with two HDMI screens, as shown in the image below:

The mouse often jumps to Screen 1 while you're moving it, which can be tolerable in some cases. However, when the CPU is busy, the mouse jumps to Screen 1 every few seconds, making it impossible to use the environment until the CPU has calmed down.

There are several possible causes for this issue, including:

Graphics Driver Issues: Outdated or corrupted graphics drivers can cause mouse jumping and other display-related problems.
Conflicting Window Managers: If you're using a custom window manager or a combination of window managers, it may be causing conflicts that lead to mouse jumping.
System Resource Overload: When the CPU is busy, it can cause system resource overload, leading to mouse jumping and other performance issues.
Hardware Compatibility Issues: Incompatibility between your laptop's hardware and the HDMI screens can cause display-related problems, including mouse jumping.

While no remediations have been effective in resolving this issue, we'll explore some potential solutions to help you overcome this problem:

Update Graphics Drivers: Ensure that your graphics drivers are up-to-date. You can check for updates in the Ubuntu Software Center or by running the command sudo apt update && sudo apt full-upgrade.
Disable Window Manager: Try disabling your window manager and see if the issue persists. You can do this by running the command sudo systemctl disable <window_manager_name>.
Increase System Resources: If your CPU is busy, try increasing system resources by closing unnecessary applications or reducing the number of open windows.
Check Hardware Compatibility: Ensure that your laptop's hardware is compatible with the HDMI screens. You can check the manufacturer's website for compatibility information.

If the above remediations don't work, you can try some advanced troubleshooting steps:

Check System Logs: Check the system logs for any errors or warnings related to the graphics driver or window manager. You can do this by running the command sudo journalctl -u <service_name>.
