Great, thanks for that. 2 things: 1. https://play.google.com/store/apps/details?id=com.realvnc.viewer.android on Dex will hide the linux cursor effectively having only your android cursor. Tested on Dex, not on the phone. 2. synaptic-pkexec wont work. You need to sudo synaptic, it works for me if you launch it from the tray. Of course not from the menu.
