This means that networktablet (or another app using the same port) is already running. You can see a list of running applications and their UDP ports with sudo netstat -an | grep udp.
Use as pointer
I’m not sure if this is an issue, a feature request or just a user error. Is there any way to use this to control the pointer on the pc? I’d be able to select all my brushes and settings and know where I’m pointing outside of the canvas.
I’d like this too. Maybe a setting to use it as a laptop trackpad to move the cursor, instead of as a stylus?
This would be great, for normal tablet users.
