Nesting X Servers with Xnest

Switching from one X session to another is fine, but doing this makes it hard to continue working on two desktops. To avoid constantly switching back and forth, I have been running a program called Xnest. Xnest, part of the XFree86 distribution, is interesting because it is both an X client and server all in one. It literally is a nested X server. Before I continue, I probably should let you know that although it is part of X, it may not be installed already on your system; however, the package (XFree86-Xnest) is likely on your distribution CDs.
