I have two computers running Ubuntu, one belongs to me and the other to my father. He often requires assistance with the system which involves using remote control. Both of the computers are connected to the same WLAN.
How can I set up a simple system for screen sharing and remote control? I would prefer something that runs in the background so that he doesn't need to click on anything (he's a bit of a technophobic). And I can assist him quickly.
I would appreciate any simple to set up and use programs.
