Recently i stumbled upon the need to hide the mouse cursor when inactive. Unclutter works by hiding the X11 cursor and should work for all linux distributions with X as display server.

Install it from the repository or download it from the project’s website.

sudo apt-get install unclutter

Then just run it with

unclutter -idle 10

To get it to autorun just add it to your startup applications. I did this on Rasbian with LXDE desktop so we just edit the autostart file:

sudo nano /etc/xdg/lxsession/LXDE-pi/autostart

and add a new line with

@unclutter -idle 10

Now the cursor will hide itself after 10 seconds of inactivity every time you log into your LXDE desktop!
