I wanted a second monitor for my desktop, but I don’t have the money. So I took my old Dell Latitude C600 and took the Puppy Linux 2.15 disk that I had laying around and installed it. I then installed the FreeNX client dotpup that I found here. I already had the NX server installed on my Ubuntu Desktop, so it was just a matter of letting my laptop through my firewall and logging in through the client on my laptop. Now I sort of have a second monitor and/or computer. I now have access to all of my programs and files, and also the power of my desktop. This is similar to VNC, but much faster.  Another difference is that I am not controlling the desktop on my other computer, but I am logged in as another user or the same user. the only time I can tell that it is not my laptop that I am actually using is if I want to use a program such as games or TVtime, some won’t launch and others have very low frame rates, YouTube videos are also choppy.
