1. Installation and Configuration
Ubuntu Unleashed
Chapter 1
Installation and Configuration

2. Pre-Installation Know your hardware How much RAM?
The more the better, at least 2 Gig for our purposes
Processor – 32 or 64 bit? How many cores? Speed?
Anything with a Gigahertz processor or better. 64 bit quad core or better preferred
Hard Drive size?
At least 5 Gig free for installing Ubuntu, plus another 30 Gig or more for installing additional distros through virtualbox.

3. Installing Ubuntu The preferred way (for class):
Set computer to boot to optical drive (DVD)
Boot to the disc in your book - choose “Try Ubuntu”
Look for the “install” link on the desktop – run it
Choose to not update at this time (box unchecked)
Leave all settings on default (click next, next, etc)
Make your username and your password “linuxes”

4. Installing Ubuntu cont.
If the preferred way cannot happen:
If you cannot dedicate a computer to Ubuntu you have the option of installing virtualbox (Virtualbox) on your Windows or Mac
Once virtualbox is installed create a new virtual machine. Match the specifications from the previous slide. Go with a 8 Gig virtual hard drive.
Start the virtual machine and point the program to your optical drive with the Linux disc from your book
Don't dual boot -
Dual booting with Windows can often cause problems with your Windows operating system. At this point in your journey to understanding Linux it's not recommended

5. Finding Programs and Files
Using Dash
Click the Ubuntu symbol in upper left corner to open Dash
Think of Dash as you would the search option in Windows
You'll have some main categories, or you can start typing in search terms
Click on the desired search results

6. Updating Software Open Dash Type “software updater”
When it opens, the program will compare installed software against available repositories and offer to update any that have available updates
Uncheck the check box next to any software you don't want updated.

7. Updating Software with the Terminal
Open Dash
Type “terminal”
A command line window will open
You should see your username followed by something like :~$
Type (in lowercase – yes it matters)
sudo apt-get update Then type
apt-get dist-upgrade
Your updates will install

8. Using sudo sudo gives you temporary “root” privileges
To have root privileges means you have ultimate control over the operating system. This can be dangerous. A normal “user” account cannot damage Ubuntu to the point where it can't be fixed. A root account can break Linux for good
Just type “sudo” before any command that requires root. Don't know if your command requires root? Try it with and without sudo and look at the different responses
When using sudo, you will be asked for your password. Don't forget it. (hint: it's linuxes)

9. Configuring Ubuntu through the GUI
Configuring Repositories
Go to Software Updater – click settings
Canonical-supported must be checked
System Settings
Dash – system settings
Shows many configurable settings, including
Printer setup
Power Management
Date and Time
Wireless network configuration

10. Congratulations! You have now installed Ubuntu Linux!
Play around in the GUI for awhile, change some settings, change your background, play a game.
In other words, get comfortable with Ubuntu.
