So I'm working on a project with my pi4 where I use a touch foil for interaction. It behaves just like a regular mouse but without the cursor. So to set the foil up correctly I need an application to show me the current location of the users input (via touch) or a method to show the mouse cursor all the time.

thanks!

  • If you boot into a GUI on the rpi4, isn't the mouse cursor shown by default? Or are you looking for a command line application?

You could look into evtest-qt, it is:

... a simple input device tester for Linux, it is analogous to the evtest command line tool, but with a Qt based GUI. It provides a list of attached input devices and displays which axis and buttons are pressed.
