= Current/stable Live CD Images = Any Ubuntu Cd can also be used as a LiveCd as well as an installer. Windows people might be more familiar with the term 'boot cd' or 'bootable cd' but a "LiveCd session" is typically much more useful because it gives a normal desktop environment and all the normal programs - it should find the machine's internet connection and allow you to use Firefox from the top panel/taskbar to surf the internet.

== Downloading == Most other versions of linux (distros), not just Ubuntu, have this functionality on their installer Cd too. With most other distros you usually have to click 2 or 3 buttons to configure the network connection so it tends to be fairly easy but not as easy as Ubuntu :) http://distrowatch.com

 * [http://releases.ubuntu.com/warty/warty-release-live-i386.iso WartyLive v1 ].Has 2.6.7 kernel, uses non-floppy emulation for booting, bootsplash, Gnome splash and wallpaper rebranding complete. See Bugs section below for known issues, feedback is greatly appreciated. While a LiveCd session is a good way to demo Ubuntu to see how it works "without making changes to this machine" it is slower than a full proper install running from a hard-drive. The reason is because the Cd/Dvd-drive is usually a lot slower at read/writes. LiveCd sessions can also be tricky to keep data and settings between sessions but you can always use a 'persistent image', perhaps on a usb-stick - see later.

  * Hardware detection
  * System configuration (locale, network, etc.)
  * X server configuration
 * Look and feel more like an installed Ubuntu system
 * Provide a framework for advanced features
  * Session save/restore
  * Live USB media
  * Live netboot sessions

== Testing ==

Notes and caveats:

- Log in as 'root' for now
- The boot process asks a few too many questions. This will be fine-tuned as development continues
- X isn't configured yet (but this work is nearing completion). If you can copy in a working xorg.conf, run `/etc/init.d/gdm start` to start an X session

Here you'll find some testcases https://www.ubuntulinux.org/wiki/QAtesting. Feel free to add more cases.

Introduction

Any Ubuntu Cd can also be used as a LiveCd as well as an installer. Windows people might be more familiar with the term 'boot cd' or 'bootable cd' but a "LiveCd session" is typically much more useful because it gives a normal desktop environment and all the normal programs - it should find the machine's internet connection and allow you to use Firefox from the top panel/taskbar to surf the internet.

While a LiveCd session is a good way to demo Ubuntu to see how it works "without making changes to this machine" it is slower than a full proper install running from a hard-drive. The reason is because the Cd/Dvd-drive is usually a lot slower at read/writes.

Reasons for Using a LiveCd Session

LiveCd sessions are good to use for;

  • a quick 'demo' on a machine before installing/upgrading Ubuntu
    • to check the hardware works as expected
    • to see if you like the look & feel of the distro

    • to prepare yourself & your unique hardware if required

  • various repair tasks such as
    • repairing grub after (re)installing Windows as part of a dual-boot
    • resizing partitions to give Ubuntu more (or less) room
    • adding a new partition(s) to your hard-drive for other distros

  • a safer and faster way of surfing the internet or even other uses of a machine that isn't your own. This is particularly good if you have a usb stick or something to save your data and settings on (see 'persistent image')

Preparation

You need an Ubuntu Cd although it's also possible to get a "LiveUsb session" from a Usb stick and this is often also referred to as a "LiveCd session" because it does offer much the same functionality, perhaps a little more.

Using the LiveCD

After you get your CD, pop it into any computer and reboot the computer. Ubuntu will load. After you are done, shut the computer down and remove the CD.

Keeping your LiveCD settings

If you want to save your LiveCD session to a USB stick, check LiveCDPersistence

Making a customised LiveCD

Common issues with a LiveCD

Logging in

You can set a password during a LiveCD session by opening a terminal, and typing in:

$ sudo passwd ubuntu

Text-Mode installation

If your normal installation fails without giving an error message, or if you want to install on a very limited system, you can use the text-based installer instead.
