Читать книгу Linux Bible - Christopher Negus - Страница 15

Use these exercises to test your skill in using a GNOME desktop. You can use either a GNOME 2.x (Red Hat Enterprise Linux up until RHEL 6.x) or GNOME 3.x (Fedora 16 or later or Ubuntu up to 11.10, or later using the Ubuntu GNOME project) desktop. If you are stuck, solutions to the tasks for both the GNOME 2 and GNOME 3 desktops are shown in Appendix B.

1. Obtain a Linux system with either a GNOME 2 or GNOME 3 desktop available. Start the system, and log in to a GNOME desktop.

2. Launch the Firefox web browser, and go to the GNOME home page (http://gnome.org).

3. Pick a background you like from the GNOME art site (http://gnome-look.org/), download it to your Pictures folder, and select it as your current background.

4. Start a Nautilus File Manager window, and move it to the second workspace on your desktop.

5. Find the image you downloaded to use as your desktop background, and open it in any image viewer.

6. Move back and forth between the workspace with Firefox on it and the one with the Nautilus file manager.

7. Open a list of applications installed on your system, and select an image viewer to open from that list. Use as few clicks or keystrokes as possible.

8. Change the view of the windows on your current workspace to smaller views of those windows you can step through. Select any window you like to make it your current window.

9. From your desktop, using only the keyboard, launch a music player.

10. Take a picture of your desktop, using only keystrokes.
