Booting Ubuntu Linux Live
CSCI 130 – Fall 2008
Action Lab
Dr. W. Jones
Introduction – What is Linux
Linux is an operating system
Linux is FREE
Linux is perfect for software development
Linux is perfect as a SERVER
Web, email, ftp, NFS file, application
Linux is NOT great for 3D gaming
Many common IDEs and compilers are FREE
Not many titles are released for Linux
There are many ‘distributions’ of Linux
Ubuntu, RedHat, Fedora, Debian, Suse, Gentoo, Slackware, etc
Booting Ubuntu from Live CD
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 testdrive it is by booting the OS directly from the CD.
Booting Ubuntu from Live CD cont
In order to boot from the CD we must make sure that
there is a proper boot order. The computer must attempt
to boot from the CD first before the hard drive (HDD).This
can be done two ways. (keep in mind that your laptop
may already be configured this way) If you have a newer
laptop, it may have an option presented after a restart just
as the BIOS (Basic Input Output System) posts. This
option may be referred to as a “Boot Menu”. If so, hit the
specified key to allow the system to boot from the CD
first. If you do no have this, you’ll have to enter the BIOS
and configure the boot sequence manually. You may
need to ask your instructor for further information.
BIOS Post Screen
Place the Ubuntu CD into
the tray, and boot to the
CD (using the methods
previously described)
After Booting Into Ubuntu You’ll See
The “Panel”
Now we should do some initial configuration
Adding “Widgets” to the Panel
Right-click on the
panel, and click “Add to
I personally like:
Frequency Scaling
Battery Monitor
System Monitor
WorkSpace Switcher
Don’t spend too much time on this, since we’re booting from the
Screen Lock
CD, any changes here will be lost. You can use a USB key to store
the changes, but that is beyond the scope of this exercise.
After Adding Widgets You’ll See
HINT: You can configure many widgets by right-clicking on them.
Check Out What’s In the Menus
Just look around and see the names of what is
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”
The idea here is to learn a little about what Linux has to offer.
Now might be a good time to “get on the
Getting On the Network
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
As you laptop connects, you’ll see
some animation here.
After successfully connecting to
wireless, you should see:
Adding New Free Software
Synaptic is one way of
searching for and
adding new software.
It can be found in:
Administration 
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:
Save the hello_py.tar.gz file to
/home/<your userid>/
Then open a terminal using this icon you
installed on the panel.
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_py.tar.gz
At the prompt, type “tar xvfz hello_py.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?
Changing Directories (Folders)
Type “cd hello_py”
This switches you to the “hello_py”
Do another “ls”, what do you see?
There are many Linux commands, don’t
worry if you feel a little overwhelmed at first
Running a Python Program from the
Command Line
Type “python”, press enter
Type “./hello2, press enter
Is there any difference in output?
Check out the code on the next slide:
Invoking the Python Interpreter
This one has executed using the python command at the prompt:
This one already had a directive at the top telling the shell
where to look for the required interpreter.
Now For Some More Fun
Go to the synaptic package manager
Search for “chromium”
Install it
Run it by going to
