1. The system displays the following message when you attempt to log in with an incorrect username or an incorrect password:

a. This message does not indicate whether your username, your password, or both are invalid. Why does it not reveal this information?
It does not differentiate between an incorrect username or password. It prevents guessing.
b. Why does the system wait for a couple of seconds to respond after you supply an incorrect username or password?
It’s so users can’t run a script and put in about 100,000 guesses a second.

It brings up window options. You can resize it, move it or keep it as the top window.
6. How would you swap the effects of the right and left buttons on a mouse?
What is the drag-and-drop threshold? How would you change it?
Go to the mouse prefference window and change it from right to left handed. It’s how far you must drag the object so the system knows it has dragged something.

What are the functions of a Window Operations menu? How do you display this menu?
A panel is a bar that appears on the desktop and holds objects.
Each rectangle in the Workplace Switcher applet, the group of rectangles near the right end of the Bottom panel, represents a workspace. When you click a rectangle, the Switcher displays the corresponding workspace and highlights the rectangle to indicate which workspace GNOME is displaying.
One Window List applet appears on the Bottom panel for each window that is open on or iconified from the displayed workspace. Left-clicking this object minimizes or restores its window. A right-click displays the
Window Operations menu. If a window is buried under other windows, click its Window List applet to make it visible

Hands-on Exercises: To prepare for this lab you must have installed the KDE desktop during installation or you can add it now. NOTE: Your screen shots may not look exactly like these because of Fedora version differences.

1. First you need to install the Guest Additions for Virtual Box or VMWare:

2. Now let’s install the KDE desktop. I assume you did not install it during initial installation so we will use yum (yellowdog update manager) to go on the Internet and download the files for KDE and install them. Use the following commands, as root, from a terminal window prompt: yum install @kde-desktop Now log out, and when you log back in you should see the option on the log on screen to log onto the computer with the KDE desktop. Screen print the desktop, it should have a start menu with this icon:

3. Do a screen print of your screen that looks like the KDE Help Center screen. Having trouble getting in. When I try to login it shows it booting then goes to a blue screen. [pic]
