I'm planning to use my 7" Android tablet as second screen via VNC.
Sharing my main screen works fine with x11vnc, but that is not what I want.
So I created a second screen using the xorg86-video-dummy driver and share this screen with
x11vnc -display :1 which works but I don't get it managed to use xrandr "extending" this screen with the main screen... .
What am I doing wrong or is there a better solution? The driver for the main screen is the cs nvidia one.
