How to Control Multiple Computers with a Single Keyboard and Mouse
What You’ll Need:
Two or more computers on the same local network.
Synergy for Windows: If you’ll be running one or more Windows PC’s in your setup, download and install the Synergy Installer for Windows on each PC. (As of this writing, the current version is labeled 1.4.2 beta.)
SynergyKM for Mac: If you want to run one or more Macs on your setup, download and install SynergyKM on each Mac you want to use.
Note for Linux users: I haven’t tried it, but quicksynergy looks like it could be a good graphical interface for Synergy. If you know of a better option, let’s hear it in the comments.
Before you get started, you need to know two terms: server PC and client PC. When you set up Synergy, you’ll have one “server”: this is the computer that has the keyboard and mouse physically connected to it. The rest of the computers will be “clients.” First, set up the server.
Set Up the Synergy Server
Download Synergy for Windows (link below )and install it on your PC. As of this writing, the most current version is Synergy 1.4.2. Install and run Synergy, then select Server (Share This Computer’s Mouse and Keyboard).
Then click the Configure Server button to open a Server Configuration dialog, where you’ll add all the computers that will be controlled by the server’s keyboard and mouse and their position in relation to each other.
If you want to use a Mac as the server, the process is very similar using SynergyKM; launch the preference pane, select Share my keyboard and mouse, and move to the Server Configuration tab to set up your screens.
Configure Multiple Synergy Screens
In the Screens And Links tab of the server configuration, you should already see your host computer in the graphical layout screen. My server computer name is Windows, so that’s what the first Synergy screen name is.
Now, to add the other computer (your client) to Synergy, you need to know its name as well. By default, the client uses the same name as your computer on the network (for example, my server is Windows; my client is Hack).
To find the name of your computer in Windows, open your Start menu, right-click Computer, and select Properties. Your computer name is listed under Computer name, domain, and workgroup settings. On a Mac, open the Sharing preference pane; your computer name is listed in the top text input.
Once you know your computer’s names, drag and drop the monitor icon from the top right of the Screens and Links dialog onto the layout (we’re still working on your server PC); drop the new monitor icon next to your server in the same layout as your monitors are on your desk. For example, my Mac’s monitor is to the left of my Windows monitor. Double-click the Unnamed screen you just added, then enter the client’s screen name.
When you’re done, you should see two computers on the Screens and Links grid that mirror the monitor setup on your workspace. If you have a particularly wild screen position (a checkerboard of flatscreens, perhaps?), you can even set up screens on top of and below each other here.
Set Up the Synergy Client
Download and install Synergy on the client computer (the one without the keyboard and mouse connected).
If you’re Synergy client is going to be a Windows computer, download the same Synergy installer for Windows. After you’ve installed your Synergy client, launch Synergy exactly the same way as you did on the server, except choose Client (Use Another Computer’s Keyboard And Mouse). Enter the name of the server computer. To try the connection, click the Start button: first on the server and then on the client PC. Try moving the mouse off the server screen. If all goes well, it will land on the client screen safely!
On Mac OS X
If the second computer is a Mac, download SynergyKM. After you’ve installed SynergyKM, launch the SynergyKM preference pane, then choose Connect to a shared keyboard and mouse. Enter the name of the server computer in the Client Configuration tab and click the Apply Now butto
