Having multiple computers can be a blessing when trying to multi-task, but trying to control them all at once can take a lot of room. Hardware options are available. They are called KVMs, which is short for keyboard, video, and mouse switches. However these hardware options require a constant hardware connection. This makes it impractical for laptops, or when substituting the KVM for the real keyboard/mouse/screen set up is not desired.
This is where Synergy — a software option — can really shine. And yes, it works with Ubuntu.
Synergy lets you easily share a single mouse and keyboard between multiple computers with different operating systems, each with its own display, without special hardware. It’s intended for users with multiple computers on their desk since each system uses its own monitor(s).
This small piece of software is available in the universe repository. Here is a short list of features that it has.
- Synergy runs on Linux, Windows, and MacOS
- Synergy can send keyboard and mouse information across a network to another computer, even if that computer is running a different operating system.
- Synergy can send text and picture clipboard information across a network to another computer, even if that computer is running a different operating system
- Turning on Scroll Lock can “Lock” a mouse and keyboard on one screen so no accidental switches occur.
- Client machines can still use their own keyboard and mouse. They are not locked out just because you are running Synergy
- A screen can be it’s own neighbor, so you can wrap your screen around itself.
- Synergy is fully configurable for any number of screens with different links between them.
While Synergy‘s configuration files can provide a powerful way to set up your multi-computer system, most people will just want a very simple system. Luckily for them there are some great GUI‘s to get Synergy going in a snap.
Windows comes with a GUI by default with Synergy.
Linux and MacOS users can use QuickSynergy.
sudo apt-get install quicksynergy
sudo apt-get install synergy
Once Synergy is set up properly, use is as easy as sending your mouse to the left, right, bottom, or top of the screen. If a link exists at that edge, the mouse is sent to the linked machine’s screen. To disallow screen switches, just turn on scroll lock.
Synergy has some great advantages. The clipboard sharing feature really can help you out in a bind. It also allows for easy use with laptops, because there is no hardware to connect. To see more ideas on what Synergy can do go to their Tips and Tricks page.
While Synergy is a great open source solution to a multiple computer system, it doesn’t cover all bases. Synergy needs at least one screen for each computer that is running. The clipboard can be very limiting because it doesn’t allow for the copying of files, just text and copied images. Since Synergy is software and network dependent, it can fail when the network fails or if the server hangs.
Many people look at the changelog and claim this project is stagnant and dead. However a quick look at their future page and their forums indicate that the main developers are trying to add more features and bug fixes to it.
