Multiple Computers, One Keyboard: Quicksynergy Makes Sharing Simple

Justin Pot 13-08-2013

Stop jumping from one keyboard and mouse combination to another every time you switch computers. Control multiple computers using just one set – without the need for extra hardware. QuickSynergy for Linux and Mac, working with Synergy for Windows, means there’s no combination of systems that can’t be controlled this quickly and easily. If there’s more than one computer on your desk then you need to check this out.


Multiple monitors are intuitive – you move your mouse from one screen to another and simply continue controlling. But what if your desk has multiple computers on it? Can you move your mouse from one computer to another, then work on that? And what about copy/paste functionality? That, as it turns out, can be just as simple as using multiple monitors – even if you’re using different operating systems.

We’ve shown you how Synergy can bring your computer systems together Synergy- Multiple Computers On One Mouse & Keyboard Read More , but that program totally lacks a GUI for Linux and Mac OS X users – leaving users of both with with the need to create a text file in order to get things up and running. QuickSynergy brings a GUI to those operating systems, and in it’s actually a far easier GUI to use than the Windows one.

Connecting Your Screens

Let’s get the obvious out of the way first: to use QuickSynergy, you’ll need all computers to be on the same network. WiFi or wired doesn’t matter, so long as you’re connected to the same router.

The main interface for QuickSynergy is two screens: one for sharing, one for using. If you’ve used TightVNC Is TightVNC Really More Tight Than Other VNC Clients? When it comes to remotely connecting to a desktop PC or a server, most people quickly opt for installing a VNC server. It's fast, easy to configure, and best of all it's absolutely free. Once... Read More or any VNC service, you’re going to be confused by the terminology. Don’t be.

Here’s the trick: what you’re “sharing” here is not your screen, but your mouse and keyboard. So use the Sharing tab on the computer connected to the mouse and keyboard you want to use. Here’s how it looks:



Simply type the name of the machines you want to control, using the box positioned appropriately (so if you want to control a screen to the right of the computer doing the sharing, you should use the text box to the right).

Setting up the server is even simpler – you need only type the IP address of the computer with the mouse and keyboard you want to use.



If you can’t connect, check your firewall settings.

The process is a little confusing, sure, but try a couple times and you’ll get things working. And there’s nothing confusing about using Synergy once it’s set up. You’ll be able to move your mouse simply from one screen to another – it’s like the ultimate KVM. But it’s even better than a KVM, because copy and pasting text is supported. In many ways it’s as though your two computers have merged into one.

Compared To Synergy

There’s a version of Synergy for Mac and Linux already. Why use QuickSynergy at all? Well, as I mentioned, the Linux and Mac versions of Synergy require the creation of text files for configuration. That’s fine for tech-savvy users with motivation, but for less-savvy and/or lazy users QuickSynergy simplifies the process.

I have to say, QuickSynergy is much easier to use than the Windows GUI for Synergy itself. I mean, look at this thing:



What’s a “Link”? It’s used to determine a screen’s location – something made much easier by the design of QuickSynergy. I had to read the documentation just to figure out what everything does.

QuickSynergy gave me no such problems – I simply set everything up and was good to go. Compare that with the Share screen above.

    I'm sorry, but you should really be referencing your article off of the latest software versions. You are showing screenshots from Synergy versions that are very outdated and thus your article is irrelevant.

      I believe you meant, "while some info might be outdated (as all tech is prone to be), thank you for taking time out to show the world at large some neat stuff they may not have known about before!"

    Your article overlooks 'Teleport' one program I have been using for years.
    Very small program, and sits in the menu bar.

    I am using Synergy for 1+ year. The only thing which now I am looking is copy/paste between two or more systems. I think ShareMouse can do this but its costly and needs license for each machine I use it on.
