It seems you didn’t run the networktablet executable in a linux terminal. You need to start this and leave the terminal open. Only then you’ll get a connection between tablet and you operating system.
Any Chance of Having X11 display on Tablet?
I was wondering if theoretically it would be at all possible to integrate an X11 server into the app so that I could see what I have on screen on my tablet before drawing? I’ve seen a few apps for Android that have an X server running so would it be possible to combine this functionality with the pen recognition? I’d be willing to look into it if I have the time.
Try googling for: “XServer XSDL”
