Synergy

Requirements

  1. Arch Linux
  2. Xcode
  3. Mac Ports
  4. Synergy

Build

  • Install the required libraries.
sudo port install cmake
sudo port install qt5
  • Add the path of the libraries.
nano .bash_profile
PATH=/opt/local/libexec/qt5/bin:$PATH
  • Get the Synergy source code.
git clone https://github.com/synergy/synergy.git
  • Fix the GUI compilation.
cd synergy/src/gui/src
nano CommandProcess.h
#include <QObject>
cd ..
qmake
cd ../..
  • Take note of the path of the active developer directory.
xcode-select -p

/Applications/Xcode.app/Contents/Developer
  • Fix the toolchain to handle the OS X version.
nano ext/toolchain/commands1.py
def getMacSdkDir(self):
#       return "/Developer/SDKs/" + sdkDirName + ".sdk"
        return "/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/" + sdkDirName + ".sdk"
# ./hm.sh setup
./hm.sh genlist
  • Check for the supported compilers.
1: Unix Makefiles
2: Xcode
3: Eclipse CDT4 - Unix Makefiles
  • Compile the sources, specifying the OS X version.
./hm.sh conf -g2 --mac-sdk 10.11
./hm.sh build
  • Check for a successful build.

  • Copy the Client program into one of the binaries paths.
sudo cp -v bin/Release/synergyc /opt/local/bin/
  • Copy the Server program (if you want OS X to act as)
sudo cp -v bin/Release/synergys /opt/local/bin/

Server (Linux)

  • Follow these instructions to install the Synergy server from the Arch Linux Repository.
yaourt -S synergy-git
  • Configure the computers disposal.
sudo nano /etc/synergy.conf
section: screens
        client-host-name:
        	altgr = alt
        server-host-name:
end

section: links
        client-host-name:
                right = server-host-name

        server-host-name:
                left  = client-host-name
end

section: aliases
        client-host-name:
                client-host-name.some-domain
end
  • Start the server.
synergys -f

Client (OSX)

  • Start the client.
synergyc -f server-host-name

Autostart

Client

  • Configure a plist file to auto start the Synergy client whenever the user starts a session.
nano ~/Library/LaunchAgents/com.domain.synergy.plist
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple Computer//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">
<plist version="1.0">
<dict>
	<key>Label</key>
		<string>com.domain.synergy</string>
	<key>ProgramArguments</key>
		<array>
			<string>/opt/local/bin/synergyc</string>
			<string>-f</string>
			<string>-d</string>
			<string>WARNING</string>
			<string>server-host-name</string>
		</array>
	<key>KeepAlive</key>
		<true/>
</dict>
</plist>
  • Make the agent active.
launchctl load ~/Library/LaunchAgents/com.domain.synergy.plist

Server

Solution #1 (SystemD)

systemctl enable synergys@<username>.socket     # replace with the unix user name
  • Failed : The Synergy server is terminated with a core dump because the <username> must be allowed to make connections to the X server.

Solution #2 (XDM)

sudo nano Xsetup
xhost +local:<username>
sudo -u <username> synergys --daemon
  • Partly successful : until the mouse leaves the master screen to enter the slave screen. Might be due by the fact that XDM grabs the X keyboard.

Solution #3 (X Session)

sudo nano Xstartup
#!/bin/sh
pidof synergys
declare -i STATE=$?
if (( $STATE == 1 )); then
    xhost +local:${USER} > /dev/null 2>&1
    declare -i RC=$?
        if (( $RC == 0 )); then
           sudo -u ${USER} synergys -d WARNING --daemon
        fi
fi
sudo nano Xreset
#!/bin/sh
killall synergys > /dev/null 2>&1
  • Successful : this solution allows an early startup of the Synergy server, right before the user starts a X session, and die when the X session stops. However, it won't let the Synergy server run during the XDM chooser.
  • An Arch Linux package is available in the AUR
