Ubuntu® 8.10 Desktop Edition enables mobile, flexible computing for a changing digital world

Ubuntu 8.10 Desktop Edition is designed for the pervasively connected digital lifestyle. With new 3G network support, users can move smoothly from wired and WiFi networks onto 3G cellphone networks while traveling. Ubuntu 8.10 is also built to be shared - users can start a quick "guest session" on the fly and let someone use their computer to surf the web or check email, while maintaining the security and integrity of their own data. And if that person really enjoys their brief session as an Ubuntu guest, they can put Ubuntu on any USB key and take it home to install on their own computer rather than having to burn a CD.

As a bonus, all Ubuntu 8.10 users will be able to enjoy programming from the BBC, with high quality streamed content available through the default media players in Ubuntu 8.10. Canonical has worked with the BBC to make sure that much of the material is available to users in all locations.

"Ubuntu 8.10 sees us lay the groundwork for a radically different, more mobile, desktop computing environment over the next two years," says Jane Silber, COO of Canonical and head of Online Services for Canonical. "Our rapid release cycle means we can deliver the elements to support this future faster, more fully realised, and more attractively packaged than the traditional OS vendors. Ubuntu 8.10 has many features that sign-post how Linux will provide the drive and innovation in desktop computing."

"Working with open source technologies like GNOME, Ubuntu 8.10 provides exciting new features for users like creating an always-on system that seamlessly connects wireless and cellular networks," said Stormy Peters, executive director at the GNOME Foundation. "Users no longer need to worry about finding a network - their computer is always connected. This is a great step for both mobile and desktop computing."

Features

3G Support

For constant connectivity public WiFi has limitations. Improvements to the network manager in Ubuntu 8.10 makes it simple to detect and connect to 3G networks and manage connectivity. This connectivity is delivered through an inbuilt 3G modem, through 'dongle' support, through a mobile phone or through Bluetooth. It is a complex environment that Ubuntu 8.10 simplifies through a single interface and the auto-detection of many of the most popular devices.

Write Ubuntu to and Install from a USB Drive

Ubuntu has been made available to users as an image for CDs and DVDs to date. But CDs and DVDs are slower, less portable and less convenient than USB sticks. Now, a simple application in Ubuntu will allow users to write Ubuntu to a USB drive, even a modified version of Ubuntu with their data on it, so it can be carried everywhere to plug in and use on any machine.

Guest Sessions

In a world of 'always on' pervasive computing it is more likely that users lend their computers to colleagues or friends at conferences, cafes or at parties so they can check email, etc. Guest sessions allow users to lock down a session easily so a guest can use the full system without interference with programs or data.

BBC Content

Starting the media players within Ubuntu (Totem Movie Player and Rhythmbox) launches a menu of selected content from the broadcaster that is free to air. This is a mixture of video, radio and podcasts and available in high quality, much of it playable using non-proprietary codecs. Content is constantly updated via the corporation's stream and will vary dependent on location, though some content will be available for every user.

Latest Gnome 2.24 Desktop Environment*

The GNOME desktop environment project releases its latest version which is incorporated into Ubuntu 8.10. New features include a new instant messaging client, a built-in time tracker, , improved file management and toolbars plus better support for multiple monitor use with the ability to set screen resolution by monitor.

How to install Sun Java Development Kit (JDK) & Java Runtime Environment (JRE) on Ubuntu Linux

- Run the following command in Terminal:

$ sudo apt-get install sun-java6-bin sun-java6-jre sun-java6-jdk

- Set the Sun Java as the default Java:

$ sudo update-java-alternatives -s java-6-sun

- Make the Sun JVM as the first searchable JVM

used and text editor to edit the file /etc/jvm. Make sure /usr/lib/jvm/java-6-sun is the first in the jvm list.

# This file defines the default system JVM search order. Each
# JVM should list their JAVA_HOME compatible directory in this file.
# The default system JVM is the first one available from top to
# bottom.

/usr/lib/jvm/java-6-sun
/usr/lib/jvm/java-gcj
/usr/lib/jvm/ia32-java-1.5.0-sun
/usr/lib/jvm/java-1.5.0-sun
/usr

- Set JAVA_HOME and PATH

used and text editor to edit the file $HOME/.bash_profile

Append the line:

export JAVA_HOME=/usr/lib/jvm/java-6-sun
export PATH=$PATH:$JAVA_HOME/bin

- Now you can clarify you java version:

$ java -version

java version "1.6.0_06"
Java(TM) SE Runtime Environment (build 1.6.0_06-b02)
Java HotSpot(TM) Client VM (build 10.0-b22, mixed mode, sharing)

- That's.

How to resume Grub on a XP/Fedora system

If you install XP, then Fedora 7 on the same PC. Grub will be used as a loader for systems. However, If your XP corrupted, and re-installed. Grub will be lost. You can follow the operation listed below to resume Grub.

How to resume Grub on a XP/Fedora system:

After Boot-up using Fedora 7 Install Disk, there are four option:

- Install or upgrade an existing system
- Install or upgrade an existing system (text mode)
- Rescue installed system
- Boot from local drive

Select the 3rd option, Rescue installed system.

Follow the steps, until Rescue ask "Continue" to find your Linux installation and mount it ..., "Read-Only" or "Skip". Select "Skip".

Now you are in # shell.

type grub, the shell will change to grub>
....#grub

To check your Linux partition
grub> root (hd0,[TAB]

In my case, it's:
Possible partitions are:
Partition num: 0, Filesystem type unknown, partition type 0x07
Partition num: 1, Filesystem type is ext2fs, partition type 0x83
Partition num: 2, Filesystem type unknown, partition type 0x8e

Actually I don't know the meaning. But I guess partition 1 is my Linux.

grub> root (hd0,1)
grub> setup (hd0)

Now you can re-boot, and the Grub loader have been re-loaded.
