The Vanishing Pointer
In certain Ubuntu desktop environments, particularly those heavily customized or running specific accessibility utilities (like “unclutter”), the operating system is designed to automatically hide the mouse cursor. The moment you start typing on the keyboard, the cursor becomes completely invisible. While this provides a clean, distraction-free view of the text you are writing—especially useful in full-screen terminals or distraction-free code editors—it can be incredibly frustrating during general use. When you finish typing and need to click a button, you are forced to violently shake the mouse to figure out where the invisible cursor was resting.
Forcing Cursor Visibility
To maintain constant visual tracking and stop Ubuntu from automatically hiding the mouse cursor when you type, you must disable or remove the utility responsible for the hiding behavior.
In most cases where this happens unexpectedly, a background utility called unclutter is running. Open your terminal by pressing Ctrl+Alt+T. First, you can temporarily kill the process to see if it fixes the issue instantly. Type: killall unclutter and press Enter. Try typing in a document; if the mouse cursor remains visible, you have found the culprit. To permanently stop the system from automatically hiding the cursor on every boot, you should completely remove the utility. Type exactly: sudo apt-get remove --purge unclutter and press Enter (provide your password). Confirm the uninstallation. Once removed, Ubuntu will revert to its standard graphical behavior, and your mouse pointer will permanently stay on the screen regardless of your keyboard activity.
