FWIW, the procedure I used for my screencasts was:

1) Install the "openbox" window manager
2) Log out of your desktop, and log back in to an "Openbox Session" from
GDM, rather than a full GNOME session
3) Right-click on the desktop and use the menu to launch a terminal
4) Run Xephyr -- this command is a little different to the command from
the tutorial page, because the original command was segfaulting for me:

Xephyr -keybd ephyr,,,xkbmodel=evdev -screen 1280x720x24 -dpi 96 :2

5) Start the nested X session:

DISPLAY=:2 /etc/X11/Xsession
