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.

New features since Ubuntu 8.10

These features are showcased for your attention. Please test them and report any bugs you find on Launchpad:

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.

New style for notifications and notification preferences

Included in Jaunty is a simple menu which can be used to set preferences for notification icons, such as where they pop up on the taskbar. There is a possibility that Ubuntu 9.04 will get a whole new notification system, as shown in the Flash movie here:

dovecot-postfix was packaged by Ante Karamatić.

Testing wanted

There are a number of specific areas of focus in Ubuntu 9.04 where the developers could use from more feedback from users. Read on to find ways that you can use the beta to help to improve the Ubuntu 9.04 final release.

Suspend/resume testing

The Ubuntu kernel team has been gathering information about what laptops do and don't suspend and resume correctly. If you are running Ubuntu on a laptop and would like to participate to help make sure the kernel team has accurate information about Ubuntu's support for your hardware, please see KernelTeam/SuspendResumeTesting.

Hotkey testing

Hotkey handling has been a source of difficulty in the past two Ubuntu releases. Significant improvement has been made to the range of hotkeys supported in Ubuntu 9.04, but more user feedback is still needed, to help identify those hotkeys that are not yet supported. If you have a keyboard with a hotkey that doesn't function as you expect, please see Hotkeys/Troubleshooting for directions on reporting this problem in the right place.

Known issues

As is to be expected at this stage of the release process, there are several known bugs that users are likely to run into with Ubuntu 9.04 Beta. We have documented them here for your convenience along with any known workarounds, so that you don't need to spend time reporting these bugs again:

  • A bug in an Ubuntu-specific patch to X server logging code will cause X sessions to crash after they have been running for longer than a day. Users encountering this bug should upgrade to the latest version of the xserver-xorg-core package, which will be available immediately after the beta release. 328035.
