I’ve tested a synergy program to share my Linux PC mouse and keyboard to my macbook. It works well ^_^ and it’s quite easy to install. On linux, you can use “yum synergy” and on mac you can download from here. In my case, my linux PC is server (synergys) and my macbook is client (synergyc). What you have to do on your linux is create synergy config file, this is my config file:

section: screens

        MMM:

        pc01:

end

section: links

        MMM:

                left = pc01

        pc01:

                right = MMM

end

MMM is the name of the mac screen (your mac name) and pc01 is pc name. Finally, you can start linux as server by

$> synergys --config <where the file is>/.synergy.conf

For mac client side, you can start in System Preferences > SynergyKM

Synergy also provide software for windows. All info, you can find from synergy website.
