Remember, working in your root account unless you have to is a bad
idea. You could unwittingly (and permanently) alter files that are critical to the proper
performance of the operating system. Now that you have created at least
one user account, log out of root and log in to a user
account.
To log out from GNOME, go to Main Menu
Button => Log out (as shown in Figure 1-6) or simply type
exit at the shell prompt.
When the confirmation dialog appears (see Figure 1-7), select the Logout
option and click the Yes button. If you want to save the
configuration of your panel, as well as any programs which are running, check
the Save current setup option, as well.
Similarly, in KDE, you can log out of root by going to => or by simply typing
exit at the shell prompt.
By default, the panel in KDE also contains a quick launch button to log
out; it is located near the taskbar, at the center of the panel, and
looks like:
Now, you can log into your user account the same way you logged in as
root.
