Raspberry Pi is working with all its might to get them opened quickly. If a
window seems slow, look at the CPU Monitor Graph on the near right side of
the LXPanel to see if your Pi is busy processing.- If you see another window that says The XScreenSaver daemon doesn't
seem to be running on display "o:" Launch it now?, click the
OK button on that window. - On the Screensaver Preferences window, make sure the Display Modes tab is
selected, as shown in Figure 2.6. - Click the Modes drop-down and select Only One Screen Saver.
- Still in the Screensaver Preferences window, under the Modes section, scroll
through the different screen savers until you find Fiberlamp and click it to select it. - Now click the Preview button in the Screensaver Preferences window and wait a
few seconds. You should see the screen saver in action. - Click anywhere on the screen saver window to return to the LXDE graphical
interface. - Now close the Screensaver Preferences window by clicking the white X in the
right-hand corner of the window and give it a few seconds to close. - Test your screen lock by clicking the ScreenLock icon on the LXPanel. In a few
seconds, the screen saver should appear. - Click anywhere on the screen saver window. This time you don’t return to the
LXDE graphical interface. Instead, a new window pops up, stating Please
enter your password. - Type in your password and press the Enter key.

this step 23.- When the LXDE graphical interface appears again, click the LXTerminal window to
select it. - In the LXTerminal window, type exit and press Enter to close the window.
Good work! Now you know how to use the LXDE graphical interface to change various items to your
liking.
