I love having a KVM but cords are expensive and sometimes I just want to control my Linux laptop. Since I have two monitors on my Desk, how cool would it be if I could control the laptop with my desktop keyboard and mouse. Well this is where Synergy comes into play.
Just start a server, click Configure.
Start the Server and connect with your client. If your Client is Linux, just install synergy.
apt-get install synergy
synergyc <Server IP>
synergyc is the client and synergys is the server. Now you can control multiple Laptops and Desktops with one single Keyboard and Mouse, over IP. By the way it works great on Wireless.
