Use A Laptop LCD To Extend Your Desktop Display

I get an email asking for this almost monthly, and [PUNiSH3R]’s take on this covers everything pretty well. He uses some interesting tricks with WINE to get enough performance to play a DVD on the remote display. Yes, the cheapest way is to turn it into a remote desktop display over a network. Personally, I use synergy2 to share my keyboard and mouse, run multiple OS’s and keep my sanity.
