It is possible to automatically login to Xubuntu.

Automatic login is highly discouraged because it provides less security for your system. Also take care when in the Login Settings application as there are options which may prevent Xubuntu from logging in or starting properly.

Open <menuchoice><guimenu>Applications</guimenu><guisubmenu>Settings</guisubmenu><guimenuitem>Login Window</guimenuitem></menuchoice>.

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 <menuchoice><guimenu>Applications</guimenu><guisubmenu>System</guisubmenu><guimenuitem>Users and Groups</guimenuitem></menuchoice>. You must be an <link linkend="administrative"><application>administrator</application></link> to do this.

See the <ulink url="http://library.gnome.org/users/users-admin/stable/tool-introduction.html">Users Administration Tool manual</ulink> for more information on setting up user accounts.

Xubuntu developers often issue updates to the Xubuntu software. These updates may improve security or fix other problems.

When updates are available, the update icon (an orange star) appears in the panel, usually near the top right of the screen. To install updates you must be an <link linkend="administrative"><application>administrator</application></link> and the computer must be connected to the Internet.

To check for updates yourself, choose <menuchoice><guimenu>Applications</guimenu><guisubmenu>System</guisubmenu><guimenuitem>Ubuntu Update Manager</guimenuitem></menuchoice> and press <guibutton>Check</guibutton>.

To change how often Xubuntu checks for updates, or to set updates to install or download automatically, choose <menuchoice><guimenu>Applications</guimenu><guisubmenu>System</guisubmenu><guimenuitem>Software Sources</guimenuitem></menuchoice>, and then <guilabel>Updates</guilabel>.

You can lock your screen in the following way:

Press <keycombo><keycap>Control</keycap><keycap>Alt</keycap><keycap>Delete</keycap></keycombo> to lock the screen. This keyboard shortcut can be changed in <menuchoice><guimenu>Applications</guimenu><guisubmenu>Settings</guisubmenu><guisubmenu>Xfce 4 Settings Manager</guisubmenu><guimenuitem>Keyboard</guimenuitem></menuchoice>.

More advanced users may wish to use the UFW firewall, which is installed by default. See the <ulink url="https://help.ubuntu.com/community/Uncomplicated_Firewall_ufw">UFW community documentation</ulink> on the Ubuntu wiki for more information.

Only download and run software from sources that you trust. By default, you can only download software directly from Xubuntu.

To restore a backup made with <application>HUBackup</application>, press <menuchoice><guimenu>Applications</guimenu><guisubmenu>System</guisubmenu><guimenuitem>Home User Restore</guimenuitem></menuchoice> and follow the instructions on-screen.
