Most linux distros just require setting the ssid some something unique and then changing the connection type to Ad-Hoc. For example, in gentoo (my distro.) all I need to do is add two lines to /etc/conf.d/net and I am done. Ubuntu probably has a graphical app to do the same thing with otehr distros filling in somewhere...
