Hiding the mouse cursor

You might notice the mouse cursor is shown on top of your window even though you don't want to use a mouse in your embedded system. To hide the mouse cursor, you can use the xdotool command to move it to the bottom-right corner pixel, so it's not noticeable, but is still available if you want to occasionally plug in your mouse to debug the device. Install xdotool and create a short Linux script to run it with Cartoonifier:

sudo apt-get install -y xdotool
 cd ~/Cartoonifier/build

After installing xdotool, now is the time to create the script, create a new file with your favorite editor with the name runCartoonifier.sh and the following content:

 #!/bin/sh
 # Move the mouse cursor to the screen's bottom-right pixel.
 xdotoolmousemove 3000 3000
 # Run Cartoonifier with any arguments given.
 /home/pi/Cartoonifier/build/Cartoonifier "$@"

Finally, make your script executable:

chmod +x runCartoonifier.sh

Try running your script to make sure it works:

DISPLAY=:0 ./runCartoonifier.sh
