Click OK to close the screens window when you are ready, then click on Start to start the server.This opens a window in which you can add screens depending on how many computers/screens you have: just drag the screen icon in the top-right corner to the screens area, and double-click it to edit its settings.Select the option Server (share this computer's mouse and keyboard).(Note that the Synergy GUI will not let you enable encryption without a valid license, whereas the Barrier GUI allows doing so.) To activate the SSL plugin, add the -enable-crypto option. $ sed -e "s/.*=//" -i ~/.synergy/SSL/Fingerprints/Local.txt $ openssl x509 -fingerprint -sha1 -noout -in ~/.synergy/SSL/Synergy.pem > ~/.synergy/SSL/Fingerprints/Local.txt $ openssl req -x509 -nodes -days 365 -subj /CN=Synergy -newkey rsa:4096 -keyout ~/.synergy/SSL/Synergy.pem -out ~/.synergy/SSL/Synergy.pem To generate a certificate and fingerprint for the server to use. This is useful when the service cannot connect to an X server on boot. Tip: You can enable synergys.socket to start the server when a client tries to connect instead. A fork called Barrier was created to continue development of the 1.x branch, containing many bug fixes and new features. Work on Synergy has stalled recently due to Symless (the company behind Synergy) halting further development of the the 1.x branch and concentrating on 2.x branch, which is primarily closed-source, configured through a hosted web interface and requires a paid subscription.
Furthermore, it synchronizes screen savers so they all start and stop together and, if screen locking is enabled, only one screen requires a password to unlock them all. Synergy also merges the clipboards of all the systems into one, allowing cut-and-paste between systems. Redirecting the mouse and keyboard is as simple as moving the mouse off the edge of your screen. It is intended for users with multiple computers on their desk since each system uses its own monitor(s). Synergy lets you easily share a single mouse and keyboard between multiple computers (even with different operating systems) without the need for special hardware. Reason: Page contains synergy specific instructions, that need to be rewritten to barrier specific.
