  1. Installing Ubuntu LinuxCSCI 140 – Fall 2008Action Lab Dr. W. Jones

  2. Introduction – What is Linux • Linux is an operating system • Linux is FREE • Linux is perfect for software development • Many common IDEs and compilers are FREE • Linux is perfect as a SERVER • Web, email, ftp, NFS file, application • Linux is NOT great for 3D gaming • Not many titles are released for Linux • There are many ‘distributions’ of Linux • Ubuntu, RedHat, Fedora, Debian, Suse, Gentoo, Slackware, etc

  3. Installing Ubuntu There are many ways to install Ubuntu. Some (common ways) require resizing and re-partitioning your hard drive. Since you’ve probably already got Windows XP or Vista running on your laptop, a fast and safe(er) way to install it is by installing it from the CD as the directions that follow prescribe. First, boot into Windows and place the CD in the drive. If it does not autorun, go to the drive in My Computer for example, and double click on it.

  4. After Booting into Windows 1. Click on “Install Inside Windows” 2. You have to choose a potential size of the file system you want to have access to after Ubuntu is installed. I’d recommend around 8GB. No less than 3. Enter you CCU userid, but you may want to use a different password. Then click Install. This will take some time, be patient, it’s worth it!

  5. After Initial Installation Click Finish to Reboot Now. It is VERY important that you allow your computer to completely reboot into Windows first before trying to enter Ubuntu. Gracefully shutdown Windows, and then after BIOS post, select Ubuntu from the bootloader.

  6. After BIOS Post You’ll See Again, make sure that after the initial install, you let Windows completely reboot and then gracefully shutdown before selecting Ubuntu on subsequent boots.

  7. After Logging Into Ubuntu You’ll See Networking The “Panel” Menus FireFox Now we should do some initial configuration

  8. Adding “Widgets” to the Panel • Right-click on the panel, and click “Add to Panel” • I personally like:Frequency ScalingBattery MonitorSystem MonitorWeatherWorkSpace SwitcherScreen Lock

  9. After Adding Widgets You’ll See HINT: You can configure many widgets by right-clicking on them.

  10. Check Out What’s In the Menus • Just look around and see the names of what is there. • We’ll be needing a terminal later, so go to:Applications Accessories Then move the mouse over “Terminal” and LEFT-CLICK and click “Add to Panel” • Now might be a good time to “get on the network”

  11. Click on the network icon and select CCUUnwired. If this is not available, your wireless chipset may not be ‘easily’ supported by Ubuntu. Try connecting your laptop to a wired Ethernet connection. Getting On the Network As you laptop connects, you’ll see some animation here. After successfully connecting to wireless, you should see:

  12. Synaptic is one way of searching for and adding new software. It can be found in: System Administration  Synaptic Adding New Free Software You’ll need you password to access this feature

  13. In Synaptic, do a search for “Sun Java” Scroll down and look for “sun-java6-sdk” Click the box and click “Mark for Installation” Then click “Apply” in Synaptic, and then “Apply” again Installing the Sun Java SDK

  14. Let’s Download a Linux-type Zip File • Linux often uses a tar.gz file type to agglomerate and compress multiple files • You may need to set the preferences in Firefox to ask you for a save locations. (you’ll want to specify where to save files) • Go to: http://ww2.coastal.edu/wjones/linux • Save the hello.tar.gz file to /home/<your userid>/ • Then open a terminal using this icon you installed on the panel.

  15. Unzipping the file • Once the terminal appears, you should be able to type “ls” at the command prompt and see your files. • Keep in mind, Linux has all the same abilities to use things like “explorer” and other GUI interfaces in Windows using point and click, but for the sake of learning something new, we’re doing it this way. • You should see the file: hello.tar.gz • At the prompt, type “tar xvfz hello.tar.gz” • You can use the tab key to quickly spell out the rest of the name for you, type typing just the first couple letters of the filename and then press tab. • Now, press enter. • Now type “ls” again, what do you see now?

  16. Changing Directories (Folders) • Type “cd hello” • This switches you to the “hello” subdirectory • Do another “ls”, what do you see? • There are many linux commands, don’t worry if you feel a little overwhelmed at first

  17. Compiling a Java program • Type “javac hello.java”, press enter • Do an “ls” what has now appeared in the directory? • To run the java program, type “java hello”, press enter. • Check out the java code on the next slide:

  18. What Does This Code Do?

  19. Try Passing a Command-line Parameter • Type “java hello John” • Type “java hello 10” • What seems to be the case?

  20. Now For Some More Fun • Go to the synaptic package manager • Search for “chromium” • Install it • Run it by going to “ApplicationsGamesChromium”

  21. OpenOfficeA Free Alternative to MSOffice • From Ubuntu Menu at top left of screen: Goto: Applications Office  OpenOffice Word Processor • After it opens, type out a short test memo and save it as a MS Word 97/2000/XP file (using the File menu) • In Firefox, login to your CCU webmail and email yourself a copy of the file. Later in Windows, see if you can open the file. Does it look the same? • In OpenOffice, try exporting the file as a PDF (in the File Menu) • From Ubuntu Menu at top: Goto: Places  Documents Find the exported PDF of the test memo. Double Click on it.

  22. PDFs Continued • What application opened the PDF document? • Hint, after it opens, goto Help About in that application • What if I want to use Acrobat Reader? • It doesn’t seem to be in the Synaptic Package Manager. (search for adobe or acrobat). That’s because Acrobat Reader in not in one of the repositories that come loaded in Ubuntu due to legal reasons. To add this repository, goto: • https://help.ubuntu.com/community/Medibuntu

  23. Adding New Repository From the Command Line • Folllowing the directions on that site: • Open a terminal and type:sudo wget http://www.medibuntu.org/sources.list.d/hardy.list -O /etc/apt/sources.list.d/medibuntu.list • Then type:sudo apt-get update && sudo apt-get install medibuntu-keyring && sudo apt-get update • (These lines can be copied/pasted by highlighting the string in the browser, and then using the middle mouse button in the terminal)

  24. Finish Installing Acrobat Reader • After that is done, reopen Synaptic, and do a reload. You may get a message about Medibuntu not being authenticated. Accept it. • Then search for adobe and select ‘acroread’. Apply this, and install it. • In a new terminal (or in the one that was already open type rehash), type acroread • This should open acrobat reader.

  25. Reopen PDF in Acroread • Double-click on the test memo in Places  Documents • Does it open in acroread? • So, right-click on the document icon, and select with “open with application” • If acrobat is not listed there, we need to browse to it on the HDD. Where would it be? • Open a terminal and type: which acroread • That will tell you the path • Navigate to this location under the browser, and now it will open with acroread.

  26. GimpGNU Image Manipulation Program • Want to edit images, make transparent GIFs, logos? • Something like paintshop? • Goto: Applications Graphics  Gimp • (Keep in mind, Gimp is a complex piece of software) • Goto FileNewImage • Accept default options • Draw in the image. • Goto: File  Save As • Look at all the types of files Gimp to export to. • Much more than MS Paint!

  27. Built-in Calculator • Applications Accessories  Calculator • Once that is open, goto: View Scientific • Check out all the included functions, and bases.

  28. Set a Screen Saver • Goto: System  Preferences  Screensaver • Check out what’s available. • I like MatrixView

  29. Windows Network • Check out: Places  Network • Click on the Windows Network • Is there anything there? • At home, if you have file and printer sharing on a Windows machine enabled, you can connect to it from Ubuntu.

  30. Killing a Process • Got an application ‘hung’ or the CPU is always at 100%, you may need to kill a process. • Can be done from command-line, but: • Goto: SystemAdministrationSystem Monitor • Open Firefox in an adjacent workspace • Locate the firefox process in the System Monitor. • Kill it

  31. EvolutionAn MS Outlook-like Client • Goto: ApplicationsInternetEvolution Mail • Use your CCU email address • Email Server Type is IMAP • Server address is mail.coastal.edu • Plain Text Login • Outgoing Server is imap.coastal.edu • Plain Text Password • After the configuration is done, restart Evolution and enter password, and you should see your email! • Send a test email to and from your email at CCU and see if you see it in Evolution
