If your desk is like mine: you have multiple PCs and Laptops spread over two square meters, but do not worry I have the solution for you! Install Synergy and you'll just say goodbye, once and for all to the mess! This software, which I emphasize is cross-platform, allows you to control multiple PCs or laptops with just one mouse and one keyboard. Basically this software allows you to have two monitors on your desk and allow you to switch from the left monitor, to the second monitor just by moving the mouse out of the right border of the first one and vice versa. This sounds simple ... but be aware that we are not talking about two monitors attached to the same PC, but two different PCs even with different OS such as Ubuntu and Windows.
