How to hide the cursor


on tx2 4g R32.2, I have dual screen live video using nvoverlaysinks. Now there is a cursor on one display, how can I hide it?


How about just disable the ubuntu desktop? Is this one acceptable for you?

we have killed X11,
sudo systemctl stop gdm
the cursor is still there.

Could you take a picture or screenshot for your case?

I would tend to think a cursor means X running without a desktop manager. Are you sure X really stopped? If you do your procedure to stop X and the login manager, and look at the timestamps of “ls -ltr /var/log/Xorg.*.log”, and then start your application, does a log update? If a log updates it implies something is still running under X.
