Installing Ubuntu

There are many ways to install Ubuntu. Some (common

ways) require resizing and re-partitioning your hard drive.

Since youve 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.


4/31

After Booting into Windows

1. Click on Install Inside Windows 2. You have to choose a potential sizeof the file system you want to have

access to after Ubuntu is installed. Id

recommend around 8GB. No less than

3. Enter you CCU userid, but you may

want to use a different password. Then

click Install.


5/31

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.


6/31

After BIOS Post Youll See

Again, make sure that after the initial install, you let Windows completely

reboot and then gracefully shutdown before selecting Ubuntu onsubsequent boots.

Synaptic is one way of

Lets Download a Linux-type Zip File

Linux often uses a tar.gz file type toagglomerate and compress multiple files

You may need to set the preferences inFirefox to ask you for a save locations. (youllwant to specify where to save files)

Go to: http://ww2.coastal.edu/wjones/linux Save the hello.tar.gz file to

/home//

Then open a terminal using this icon you

installed on the panel.
http://ww2.coastal.edu/wjones/linuxhttp://ww2.coastal.edu/wjones/linux


15/31

Unzipping the file

Once the terminal appears, you should be able totype ls at the command prompt and see your files.

Keep in mind, Linux has all the same abilities to usethings like explorer and other GUI interfaces inWindows using point and click, but for the sake oflearning something new, were 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 coupleletters of the filename and then press tab.

Now, press enter.

Now type ls again, what do you see now?


16/31

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, dont worryif you feel a little overwhelmed at first

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 Word97/2000/XP file (using the File menu)

In Firefox, login to your CCU webmail and email yourself a copy ofthe file. Later in Windows, see if you can open the file. Does it lookthe same?

In OpenOffice, try exporting the file as a PDF (in the File Menu)

From Ubuntu Menu at top: Goto: Places Documents Find theexported PDF of the test memo. Double Click on it.

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 doesnt seem to be in the Synaptic Package Manager.

(search for adobe or acrobat). Thats 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


23/31

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)


24/31

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 foradobeand select acroread. Applythis, and install it.

In a new terminal (or in the one that was already

open type rehash), type acroread

This should open acrobat reader.


25/31

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 withopen 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 nowit will open with acroread.
