Mint, being based on Ubuntu, has a remote desktop program that lets you view and control one PC from another.
But unless told otherwise, it asks for permission for this on the 'viewed' PC's screen.
Clearly, at the moment that's not very useful. So where is the file to edit to tell it not to ask permission? (The PC is behind two firewalls, so I'm not worried about anyone on the net being able to get in, not least as you can also get the remote end to give a password.)
Edit: Ah ha, ~/.gconf/desktop/gnome/remote_access/%gconf.xml – where else? 🙂 Fortunately there's an example with the desired settings on L's PC.
