The [[http://nouveau.freedesktop.org/wiki/|Nouveau]] video driver is now the default for nVidia hardware. This driver provides kernel mode setting, which will give improved resolution detection. This driver provides hardware accelerated 2D functionality, like the -nv driver it replaces.

There is some [[https://wiki.ubuntu.com/X/Troubleshooting/Nouveau|troubleshooting information]] available.

The desktop has been beautified with the addition of two brand new themes, Ambiance and Radiance. New wallpaper and icons are also included.

== Ubuntu One File Syncing ==

Select any folder in your home directory for sync, pick from your existing contacts when sharing folders. An updated preferences application has been added, with more features.

== Ubuntu One Music Store ==

Millions of songs are available for purchase from your Ubuntu desktop, integrated with the Rhythmbox Music Player and using Ubuntu One cloud storage for backup and easy sync.

== New features for Ubuntu Enterprise Cloud (UEC) ==

The Ubuntu Enterprise Cloud installer has been vastly improved in order to support alternative installation topologies. UEC components are now automatically discovered and registered, including for complex topologies. Finally, UEC is now powered by [[http://eucalyptus.com/|Eucalyptus]] 1.6.2 codebase.

  * run {{{sudo /usr/lib/gdm/gdm-set-default-session --keep-old une}}} (substituting {{{xubuntu}}} or {{{mythbuntu}}} for {{{une}}} as appropriate)

  * Jockey (Ubuntu's restricted driver manager) doesn't yet support the new alternatives system used by the nvidia driver packages, so in order to install nvidia drivers you will have to install them from the command line:
   * {{{sudo apt-get install nvidia-current (or nvidia-173 or nvidia-96)}}}

   * select the alternative that matches the driver that you have installed
    (e.g. {{{/usr/lib/nvidia-current/ld.so.conf}}} for {{{nvidia-current}}}):

    {{{sudo update-alternatives --config gl_conf}}}

   * update the ld cache:

    {{{sudo ldconfig}}}

   * then configure your xorg.conf with:

    {{{sudo nvidia-config}}}
    
   * And restart your computer.
    
  * Because of the new alternatives system, the nvidia installer from NVIDIA's website (currently) doesn't work.

 * The fglrx binary driver for ATI video chipsets does not yet support the X server in Lucid. As a workaround, users should use the open source {{{-ati}}} driver instead. (Bug:506656)

 * Attempting to run 32bit applications which make use of 3D acceleration in a 64bit system will result in a failure. See (Bug:506435) and (Bug:506437). This is expected to be resolved for Alpha 3.

It should come as no surprise that this alpha release of Lucid Lynx contains other bugs. Your comments, bug reports, patches and suggestions will help fix bugs and improve future releases. Please [[http://help.ubuntu.com/community/ReportingBugs|report bugs using the tools provided]].

Introduction

The Ubuntu team is happy to bring you the latest and greatest software the Open Source community has to offer. Our newest release, the Ubuntu 10.04 LTS, brings a host of exciting new features for users.

Upgrading from Ubuntu 9.10 or Ubuntu 8.04 LTS

To upgrade from Ubuntu 9.10 on a desktop system, press Alt+F2 and type in "update-manager" (without the quotes) into the command box. Update Manager should open up and tell you: New distribution release '10.04' is available. Click Upgrade and follow the on-screen instructions.

To upgrade from Ubuntu 9.10 on a server system: install the update-manager-core package if it is not already installed; edit /etc/update-manager/release-upgrades and set Prompt=normal; launch the upgrade tool with the command sudo do-release-upgrade; and follow the on-screen instructions.

To upgrade from Ubuntu 8.04 LTS: follow the same instructions as for the appropriate Ubuntu 9.10 upgrade, but set Prompt=lts instead of Prompt=normal.

New features since Ubuntu 9.10

GNOME

Ubuntu 10.04 LTS includes the latest GNOME desktop environment with a number of great new features.

Translations

Thanks to the efforts of the broad translations community around the globe, Ubuntu is available in the following 29 languages: Spanish, English (United Kingdom), Brazilian Portuguese, German, French, Italian, Hungarian, Swedish, Russian, Chinese (Simplified), Dutch, Portuguese, Finnish, Danish, Japanese, Greek, Korean, Czech, Catalan, Polish, Galician, Chinese (Traditional), Slovenian, Bulgarian, Asturian, Vietnamese, Basque, Turkish and Serbian. Congratulations to the Asturian, Vietnamese, Turkish and Serbian teams for having made it to the list.

Here you can see the full list of languages, along with their detailed statistics.

This list represents the languages which have achieved the target of what we consider a translated operating system. However, Ubuntu is also available in many other languages with varying degrees of coverage, many of which are very close to what we consider complete.

Linux kernel 2.6.32

Ubuntu 10.04 LTS includes the 2.6.32-21.32 kernel based on 2.6.32.11.

KDE SC 4.4

Kubuntu 10.04 LTS features the new KDE SC 4.4. For more information about new features in Kubuntu, see the Kubuntu technical overview.

HAL removal

This release fully removes HAL from the boot process, making Ubuntu faster to boot and faster to resume from suspend.

Major new version of likewise-open

The likewise-open package, which provides Active Directory authentication and server support for Linux, has been updated to version 5.4. The package supports upgrades from both the officially supported versions 4.0 (Ubuntu 8.04 LTS) and 4.1 (Ubuntu 9.10), as well as the likewise-open5 packages from universe.

Since this upgrade involves a lot of configuration file changes and in-place database upgrades, testing and feedback is appreciated.

New default open source driver for nVidia hardware

The Nouveau video driver is now the default for nVidia hardware. This driver provides kernel mode setting, which will give improved resolution detection. This driver provides hardware accelerated 2D functionality, like the -nv driver it replaces. The nouveau driver is being actively developed upstream and we anticipate this will enable faster bug fixes for problems encountered. There is some troubleshooting information available.

Improved support for nVidia proprietary graphics drivers

Three different NVIDIA proprietary drivers are currently available: nvidia-current (190.53), nvidia-173, and nvidia-96. Thanks to a new alternatives system, it is now possible to install all three of these packages at the same time (although it is only possible to have one configured for use at a time).

Social from the Start

We now feature built-in integration with Twitter, identi.ca, Facebook, and other social networks with the MeMenu in the panel, which is built upon the Gwibber project, which has a completely new, more reliable backend built on top of desktopcouch. Gwibber now also supports a multi-column view for monitoring multiple feeds simultaneously.

New boot experience

Multiple changes to look, feel and speed of the boot experience have been included in the Ubuntu 10.04 LTS.

New Indicators

The notification area now features more consistent user experience and design for communication, session management, and many other tasks. See the application indicators page for information on this change.

New Themes

The desktop has been beautified with the addition of two brand new themes, Ambiance and Radiance. New wallpaper and icons are also included.

Ubuntu One File Syncing

Select any folder in your home directory for sync, pick from your existing contacts when sharing folders. An updated preferences application has been added, with more features.

Ubuntu One Music Store

Millions of songs are available for purchase from your Ubuntu desktop, integrated with the Rhythmbox Music Player and using Ubuntu One cloud storage for backup and easy sync.

New features for Ubuntu Enterprise Cloud (UEC)

The Ubuntu Enterprise Cloud installer has been vastly improved in order to support alternative installation topologies. UEC components are now automatically discovered and registered, including for complex topologies. Finally, UEC is now powered by Eucalyptus 1.6.2 codebase.

Security Issue when upgrading from Lucid Alpha 2

If you installed Lucid prior to Alpha 3, you may have libmysqlclient16 7.0.9-1 installed. This package was present in the Ubuntu archive by mistake and was retracted, but because it has a later version number than the real libmysqlclient16 package, the real package will not be installed automatically on upgrade. To ensure that you have the official package installed on your Lucid system and will receive security support for it throughout Ubuntu 10.04 LTS, it is important that you run sudo apt-get install libmysqlclient16/lucid and follow the instructions.
