Many of us have multiple computers at our desks with either two sets of
keyboard and mice or a kvm. Both cases are kind of annoying.
Wouldn't it be cool if the systems could just act like a single dual screen computer? Well, it can.
The magic program that lets you do it is called
Synergy
Synergy is a client / server program that lets you connect one keyboard
/ mouse pair to multiple (as many as you like) computers. Back in
school, we had a setup with 12 monitors and one keyboard / mouse
controlling all of them by just scrolling from screen to screen.
An advantage to this over normal dual screen setups is that if one
machine is under load, that doesn't keep the other machine from slowing
down at all. Since the software itself is very light, even a
heavily loaded serving machine can still handle being the server for
the keyboard / mouse.
