Installation and Configuration Ubuntu Unleashed Chapter 1 Installation and Configuration

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.

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”

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

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

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.

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

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)

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

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.
