At most sites, the screen automatically locks after a specified period of idleness. If you expect to leave the workstation for awhile, or if you expect someone else to use your workstation, log out.
To log out, do one of the following:
In Trusted CDE, click the EXIT icon in the workspace switch area of the Front Panel.
For a picture of the Front Panel, see Figure 3–1.
The Logout Confirmation dialog box is displayed.
In Trusted GNOME, choose Log Out your-name from the Main menu.
Confirm that you want to continue to log out.
