Add support for Synergy to connect to Kiosk machine without a keyboard or mouse

Hello! Just got my PRi SD card. So far, I’m very happy with it.

Where I intend to deploy it doesn’t have a keyboard or mouse easily at hand. The way I handle this with other systems like this is by installing Synergy on the host, which allows me to tie it in to the rest of my monitors and use the keyboard and mouse from my main computer on that machine. It makes running Linux, Mac, and Windows on one physical desk (different monitors) much easier, let me tell you.

Anyway. Helioclock will be displayed on a monitor above my main computer desk, and there’s no convenient way to connect a keyboard/mouse to it. I would very much like to just move my mouse off the top edge of the monitor directly below Helioclock and be able to control it.

Let me know if you need any help from me to make this happen or test it. Thanks!
