Ubuntu 9.04 Released !!!

Ubuntu sponsors, Canonical , announce the release of Ubuntu 9.04 destop version that can be downloaded for free now!

Ubuntu is an open source operating system with the intention of supplying an up-to-date, stable operating system for the normal computer user. In addition to stablility Ubuntu try to target ease of use and installation. Ubuntu can be used on almost anything including Desktops, Business PC’s, Notebooks and many others that are able to support x86 CPU or ARM CPUs, this has only been adapted in the 9.04 version.

One standard, but remarkable (because it outdoes Vista) feature of Ubuntu is the Compiz Fusion 3D desktop, which has enables some really cool effects. Of course, for this feature to function you need a 3D accelerated graphics card.

Upgrading from Ubuntu 8.10

To upgrade from Ubuntu 8.10 on a desktop system, press Alt+F2 and type in "update-manager -d" (without the quotes) into the command box. Update Manager should open up and tell you: New distribution release '9.04' is available. Click Upgrade and follow the on-screen instructions.

To upgrade from Ubuntu 8.10 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.


Get it while it's hot. ISOs and torrents are available at:

New Features since Ubuntu 8.10
GNOME 2.26

Ubuntu 9.04 Beta includes the latest GNOME 2.26 desktop environment with a number of great new features, including:

  • brasero, developed by Philippe Rouquier and Luis Medinas, as an all-in-one CD burning application

  • Improved handling of multiple monitors with an updated gnome-display-properties by Federico Mena Quintero.

X.Org server 1.6

The latest X.Org server, version 1.6, is available in Jaunty. A number of video cards have been transitioned to free drivers as part of this update.

The -ati driver has received numerous fixes and performance improvements. It now uses the EXA acceleration method by default. 2D acceleration support for the newest R6xx/R7xx family of cards is also available. 3D support is available up to R5xx cards for -ati. An updated -fglrx proprietary driver is available for R6xx/R7xx users who need 3D support.

Linux kernel 2.6.28

Ubuntu 9.04 Beta includes the 2.6.28-11.37 kernel based on

Ext4 filesystem support

Ubuntu 9.04 Beta supports the option of installing the new ext4 file system. ext3 will remain the default filesystem for Jaunty, and we will consider ext4 as the default for the next release based on user feedback. There has been extensive discussion about the reliability of applications running on ext4 in the face of sudden system outages. Applications that use the conventional approach of writing data to a temporary file and renaming it to its final location will have their reliability expectations met in Ubuntu 9.04 beta; further discussion is ongoing in the kernel community.

Ext4 support in GRUB was provided by Colin King. If you choose to upgrade your / or /boot filesystem in place from ext2 or ext3 to ext4 (as documented on the ext4 wiki), then you must also use the grub-install command after upgrading to Ubuntu 9.04 Beta to reinstall your boot loader. If you do not do this, then the version of GRUB installed in your boot sector will not be able to read the kernel from the ext4 filesystem and your system will fail to boot.

Ext4 support in gparted has been provided by Curtis Gedak.
