Ubuntu 9.04

Canonical, as always neatly according to the semi-annual release schedule, version 9.04 of its Linux distribution released. The Ubuntu developers, known for their love of obscure animal names in the choice of code names, have this time for a mythological animal chosen: the 'Jaunty Jackalope', which is free to translate as "the stylish get rabbit.

For the new version promises Ubuntu notably improved boat performance, thanks to the introduction of the ext4 file system. Jaunty Jackalope also has kernel version 2.6.28-11.37 and X. Org version 1.6. There are some small changes which should improve the ease of use, and the public can experience a live version of Ubuntu Netbook Remix.

We see this hands-on what changes in Jaunty Jackalope are implemented and how they influence the performance. Also we throw a look at the Netbook Remix version.

Evolution

The latest version of GNOME also has some very nice new tools for the oft-neglected Evolution mail client. Thanks to the new MAPI protocol support, Evolution should be much better at connecting to Microsoft Exchange mail servers.

Evolution also offers an easy way of importing data from Microsoft Outlook. It's tough to get too excited about desktop e-mail clients, but if you're heavily invested in Microsoft's mail system, the new tools make it much easier to migrate over to Ubuntu.

Also new under the hood is a new Linux kernel (version 2.6.28), which is primarily notable for moving the Ext4 file system to the stable category. Despite its new designation, Ext4 is not the default choice for Ubuntu. The automated install process will still format your disks with the tried and true Ext3. To get Ext4, you'll need to manually partition your disks.

We went ahead and used Ext4 for testing, and so far, we haven't run into any problems, but be warned that some users have experienced data loss with Ext4.

Also new in the kernel update are quite a few changes to the wireless system, including support for a number of new devices - there's even less chance you'll need to manually install Wi-Fi drivers.

Ext4 filesystem support

Ubuntu 9.04 RC 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 RC 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.

Cloud computing

Ubuntu 9.04 Server Edition makes it easy to experiment with cloud computing. Eucalyptus, an open source technology which is included in Ubuntu as a technology preview, enables you to use your own servers to deploy, experiment and test your own private cloud that matches the Amazon EC2 API. You can dynamically create virtual machines, configure multiple clusters into a single Cloud and even provide an EBS (elastic block storage) equivalent and an S3 compatible storage manager.

Ubuntu 9.04 Desktop Edition

Canonical has several changes and improvements in the GUI implemented. Thus X. Org arrived at version 1.6 and the Mesa 3D library, which is used by OpenGL applications, version 7.4 comes. OpenOffice.org 3.0, which just got the 8.10 release, Jaunty Jackalope is the default office suite.

Owners of ATI video cards with a GPU from the R6x/R7X-series be in version 9.04 thanks to a refreshed opensource driver benefit of improved 2D acceleration in the Gnome environment, but the 3d support for this driver is limited to the R5x -GPU 's. The video driver for Intel IGP's finally used the uxa architecture of the 2D view must accelerate. The Ubuntu developers have also falsified to display the Preferences dialog. It would be easier to multi-monitor setups to configure.

Within the familiar Gnome environment, which was updated to version 2.26, is little shocking to find innovations. Furthermore, Brasero elected standard tool for burning CDs and DVDs. The tool is easy to use and offers among others the possibility of video DVD's to make. In addition, Brasero directly from Nautilus, the Gnome file manager, to be called on to perform fire jobs.

Version 9.04 introduces Gnome within a universal way to show all kinds of system messages, as Canonical founder Mark Shuttleworth had already announced. The new notification system works nice: reports on a fixed position and with a similar design showed that the gui a professional and harmonious appearance.

Canonical also falsified the code for the standby and hibernate modes. On one of our test laptop - a Compaq 6710b - is the switch to the sleep mode when the standby mode without problems. An old desktop PC with an Athlon XP processor, an ideal candidate for an Ubuntu installation, with 9.04 also shows good standby and hibernate crossing to. In previous versions seemed successful wake of a system is a matter of luck, it seems that for this feature in 9.04 has been substantially improved.

Ubuntu 9.04 Server Edition and Netbook Remix

In the GUI-less Server Edition of Ubuntu 9.04, the necessary changes made. If the kernel contains the latest features of the KVM virtualization engine, to Samba 3.3-clustered file servers and is setting up an e-mail, according to Canonical simplified by integrating the Dovecot mail server with Postfix. Also, in version 9.04 the Exchange alternative Open Change better meet the needs of Microsoft Outlook users.

Canonical has its version on the server hardware from several major server vendors tested. Ubuntu 9.04 Server Edition would be the Ubuntu-makers work at 45 popular server systems in the mid. These servers included from IBM, Dell, Sun and HP.

Ubuntu 9.04 Server Edition will continue, as in December already known had to be included in the virtual server offering Amazon-EC2 cloud service. Canonical also claims that its Ubuntu Enterprise Cloud technology - which in the Server Edition a preview version is available - and its eucalyptus-management tool flexible enough to include in computing centers of companies to be out.

System administrators can use Ubuntu Server 9.04 to work with applications that amqp messaging protocol. It has the OS on the RabbitMQ platform. Finally, MySQL 5.1 is available, which Canonical promises that users of version 5.0 without problems can change.

Ubuntu Netbook Remix

Together with the 'full' release of Ubuntu 9.04 is also presented an image of Ubuntu Netbook Remix, a compact notebooks optimized version of the Ubuntu distribution. The image can be obtained from an image writer, also for Windows is available, a simple USB stick is inserted.

Booting Ubuntu Netbook Remix is rather easy, if a fast USB-stick is used. Canonical has a separate user interface for 10 "displays developed. This GUI offers large icons for frequently used applications, which are divided into thematic tabs classified. The menus are nicely finished, but leave it entirely to our taste a little too much on one type major smartphone without touchscreen appear. Fortunately, the normal desktop also used as the terminals.

According to Canonical Ubuntu Netbook Remix works well with most netbooks, including the Aspire One netbooks from Asus Eee PC 900 - and 1000-series, the Dell Mini 9, HP Mini Mi and Toshiba NB100. A quick test for a Medion Akoya, also an Atom netbook, are also accelerated standby and hibernate modes to work. In the near future, there appear a version supports ARM processors.

Conclusion

We can be brief: Ubuntu 9.04 does us good. The most popular Linux distributions choose again for evolution rather than revolution, instead of excessive straw with new functionality, the developers focused on improving the performance and stability. As we have Canonical and the development community that good job.

When we look to the desktop version, we are mainly talking about the rapid launch of the OS and the improved standby and hibernate modes. Also on network area has been made, though in particular wifi cards.

The server we have not been extensively tested, but Netbook Remix, we have mixed feelings. Developing a separate extra shell for netbooks is a good initiative, but the usefulness escapes us a bit. Perhaps support for touch-sensitive screens can enhance the usability, but we experienced it as an unnecessary gimmick. Fortunately, the underlying OS as well as the desktop variant.

Meanwhile the Ubuntu crew already working with Ubuntu 9.10. This version, called "Karmic Koala 'is mentioned, will be more than 9.04 emphasis on cloud computing. There should also be 9.10 of a full Netbook Edition will appear. This edition will of course build on the Netbook Remix, but it will also take note of Intel's mobile Linux project Moblin for borrowing. May be at the Ubuntu Developer Summit in Barcelona more clearly about what is still more of Karmic Koala can be expected. Until that time we feel perfectly at home in Jaunty Jackalope.

wow buddy u have provided such a great informatio about ubuntu
i also ubuntu 8.10 but now i will try this 9.04

does it hav mp3 codecs or i hav 2 install it manually.
Can it be installed inside windows partition ? (like ubuntu 8.04)

Hey!
Codec are present in the Package Manager by default, but not installed by default, you can dwonload it from there and install those whenever you want...
All the best..!

please give me the guideline to dl and install those codecs
i donot know those commands or rather the procedure

After installing ubuntu 9.04 try to play mp3 files in Totem. just double-click the any mp3 file, now if you dont have the necessary codecs to play MP3 files. It'll ask if you want to search for the appropriate codec. Click Search to continue. after searching for mp3 codec. Click Install, then Confirm. Wait for the codecs to install. Then click OK

is it download the codec from internet or it has, inside it ?

You have to download it from the internet but the list of software/codec is present in the OS's package manager. Do this :
Open terminal, just like dos and run

Code:

---

sudo apt-get update

---

This will update the packages available for your OS in the package manager. Now goto synaptic package manager and select the multimedia section from left side. Install all the available audio and video codecs. All the best!:thumbup1:
