Give a separate user account to each person

When Xubuntu is installed, it is set up for a single person to use. If more than one person will use the computer, it is best for each person to have their own user account. This way they can have separate settings, documents, and other files. If necessary, files can also be protected from being viewed or changed by non-administrators.

To set up user accounts, choose ApplicationsSystemUsers and Groups. You must be an Chapter 14, Tugasan Pentadbiran to do this.

See the Chapter 16, Users and Groups for more information on setting up user accounts.
