Emulate a KVM switch using software
Avi Dardik has a quick guide on how to set up a
secondary PC using VNC (for multi-platform support) to act like a KVM switch and allow you to switch between active
full-screen sessions on your host machine and a client machine at the tap of a hot-key.
Although many may argue that using VNC software for this purpose is a pretty ugly hack, the reality is that this
scenario is extremely common, and very fast on a local network.
The only thing I would add is that if I was going to set this up with strictly Windows PCs, I'd substitute Remote Desktop for VNC. Remote Desktop is simply so much faster and more efficient between Windows PCs that there's no reason not to. That is, of course, if you have XP Pro or a flavor of Windows Server for your "client" machine. XP Home won't allow you to make a Remote Desktop connection to it unprompted.

One good reason not to use Windows Remote Desktop is that it prevents Direct3D apps from working. Many non-game apps (even some charting, graphing and presentation applications) make casual use of Direct3D.

Jason, you suggest using Remote Desktop, which I do quite frequently from my laptop to my desktop via our home wireless network. Do you know how to get it out of what looks like 16-bit video mode?

Bryan, I use Remote Desktop as well (although from Mac to PC). Unfortunately, there's currently not a way to show high color (or true color, but whatever) using it. That's the final word from MS, though there may be hacks or other tools that fix that... Bummer, as I use it for 3d, and it just doesn't work for texturing or rendering...

Victor - I'm not sure about that. In XP when you open the Remote Desktop Connection applet, if you click on Options then the Display tab, you can choose the color depth you want to use. On the system I'm on, I can go all the way up to 24-bit True Color.

Hm, maybe it's a PC-to-Mac thing. That would figure ;-)

I'm going from XP Home (laptop) to XP Pro (desktop), maybe that's the problem. I'll have to get my laptop on XP Pro soon, or possibly try VNC. Thanks for the response.

If you don't need the V part of KVM, meaning that you just want to share a Keyboard and Mouse between two computers with their own monitors, there's a possibly better solution (especially across platforms): Synergy, which emulates a KM switch in software by transmitting the keyboard and mouse actions from a master computer to a client computer. Plus it's open-source.

Why didn't I think of this earlier?
