==The Three B's - BS, Blurb & Bug:==
 
 
 
Years ago I paid a lot of money for a really good quality four machine handling KVM switch box. It worked very well via keyboard command until the day it failed. :(  In those days when I was fixing computers, that KVM was far superior to synergy because it was hardware that was system independent & worked on anything that had a working BIOS.
 
  
For my needs today, the synergy system shits all over a KVM, though there are varying limitations which are dictated by the display manager / OS you are using.

Running Openbox, I can't make use of synergy until OB has loaded. On some Linux display managers you can use it before hand & I'm sure that OS/X & the various Windows all have their strengths & weaknesses in this regard. In the end this doesn't really matter to me as I spend very little time outside of OB anyway. So for my current computer usage synergy is all but gob smacking perfect.

All but? Yes, just one tiny bug that effects a few of us. For some users when moving the mouse from one computer screen to another you get a one or (far more rare) a two second black screen.
 
 
 
I got the one second one when moving from the client to the server. For most this is fixed by issuing the command  '''xset -dpms'''. This works for me so I issue it in ''~/.xinitrc'' so the problem never appears.
 
 
 
This problem has been around for about a year, & someone has written a patch for it inside of the last month, so I'll hang back & wait for the next release which I expect to have killed this bug, in the mean time I no longer know it exists.
 
 
 
I'm sure that this bug no longer exists, don't be put off by it.

Overview

Synergy is a brilliant piece of software that doesn't require much effort to get going, Though faultless autostart did require some configuration.

So What Does Synergy Do?

I can now use my favourite keyboard & mouse to operate two computers (synergy will do plenty more computers if you have them) one at a time of course...

With two machines set to load synergy when they boot it doesn't matter what order the server or the client is booted in.

Synergy uses next to no system resources and even shares the clipboard as well!

Bug Awareness

Running Openbox, I can't make use of synergy until OB has loaded. But some Linux display managers you can use it before hand.

While it should already be fixed, there is an old bug that can produce 1-2 second black screens. For most this is fixed by issuing the command

xset -dpms

If necessary, the command can be placed in ~/.xinitrc so the problem never appears.

The Synergy Server:

Installation:

Rather than me duplicating it, the Archwiki has a great page on Synergy installation.


Configuration:

My /etc/hosts file follows which should speak for itself:

192.168.1.3             rightpc.localdomain  rightpc         ## the HP server
192.168.1.6             leftpc.localdomain      leftpc          ## the iMac client


Synergy.conf

Here is a great start (a complete solution in my case) for a very smoothly running pair of machines (easily edited for more though), via one mouse & keyboard being connected to the synergys server - this synergy.conf is the server configuration file which does the job faultlessly for me:

#synergy.conf

section: screens
	leftpc:
		halfDuplexCapsLock = false
		halfDuplexNumLock = false
		halfDuplexScrollLock = false
		xtestIsXineramaUnaware = false
		switchCorners = none +top-left +top-right  +bottom-left +bottom-right 
		switchCornerSize = 0
	rightpc:
		halfDuplexCapsLock = false
		halfDuplexNumLock = false
		halfDuplexScrollLock = false
		xtestIsXineramaUnaware = false
		switchCorners = none +top-left +top-right +bottom-left +bottom-right 
		switchCornerSize = 0
end

section: aliases
leftpc:
192.168.1.6
rightpc:
192.168.1.3
end

section: links
	leftpc:
		right = rightpc
	rightpc:
		left = leftpc
end

section: options
	heartbeat = 1000
	relativeMouseMoves = false
	screenSaverSync = false
	win32KeepForeground = false
	switchCorners = none +top-left +top-right  +bottom-left +bottom-right 
	switchCornerSize = 4
end


This synergyc.conf file suits my uses perfectly, I found it on the Arch wiki, & it needed no functional modification. I put it in /home/handy as a <.dot> file i.e. ~/.synergy.conf .


The Synergy Client(s):

Install synergy

sudo pacman -S synergy


Client /etc/hosts:

Edit the /etc/hosts file, mine is below for those that do need to reference, & if you do make sure you compare it with the server side one posted earlier on this page:

192.168.1.6     leftpc.localdomain               leftpc          ## the iMac client
192.168.1.3     rightpc.localdomain             rightpc         ## the HP server [/code]


~/.xinitrc

Add the following to the ~/.xinitrc file (guess how I copied it?):

synergyc -d ERROR rightpc


Conclusion:

The server is where the hardest work is, beyond that it comes down to getting your auto-start sorted so that it just works no matter which machine(s) come on in what order. For me the above works in that regard perfectly once Openbox has loaded.
