I am trying to install synergy from here. When I run it I get the error:
system tray unavailable, quitting
I am running Freya.
Any help would be appreciated or the name of different software to share my mouse and keyboard with a Windows machine.
I ran into this same issue. I am using Windows 8 as my server, and Elementary OS as the client. Not sure if your setup is the same.
I used the Synergy command-line commands to start it in a Screen session;
I installed Screen (sudo apt-get install screen). Then I opened a Screen session using "screen -S synergy", and named it synergy so I knew what the screen session was for.
Then I ran the following command to start Synergy:
synergyc -n NAME OF ELEMENTARY OS COMPUTER -f NAME OF SERVER.
I then closed my Screen session using Ctrl+A+D.
Screen manual page found here. Really the only tags you need is -S then the name, and -r to reattach the screen.
The synergy client commands are found here.
The version from apt-get (1.4.12) in Freya should be working fine - just do
sudo apt-get install synergy
The last time i checked (probably around august 2015) the version of synergy available from the repo was ancient.. i got version 1.7.4 compiled, but 1.7.5 throws an error at me and doesnt actually compile the synergy executable.. but anyway, i got 1.7.4 easily running on eOS Freya by sudo apt-get installing synergy for the dependencies, but just using my compiled 1.7.4 version autostarted at boot.
i havent even checked the changelog for 1.7.5 yet, but i have an issue with the client randomly disconnecting from the server even though the log says its still connected, tried on 2 different versions of ubuntu, but it works on windows.. i donno
try installing sni-qt:
sudo apt-get install sni-qt
