I am running Mint 13 with Cinnamon 1.6. I would like my desktop wallpaper to automatically change depending on the time of day. So, the first thing that comes to mind is setting up a cron job to do it for me. Problem is, I don't know how to change the wallpaper from script / terminal.
What I would like to know:
1) How would one change the background from terminal?
2) Is the there already a built-in way of doing this?
