I have two Debian machines. One is connected to a projector for a presentation, and the other is a netbook that doesn't have a working VGA output. How can I play a presentation on the netbook, but have it displayed through the projector? I need the projector laptop to connect to the netbook somehow and display the presentation.
Turn on VNC on the machine with broken VGA output. By default it's installed as "remote connection" on Debian 7.
