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. For a little while, this will again cause increased instability for some users while the proprietary video drivers catch up.
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:
Linux kernel 2.6.28
Ubuntu 9.04 Beta includes the 2.6.28-11.37 kernel based on 2.6.28.8.
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.
Ext4 support in gparted has been provided by Curtis Gedak.
Kerneloops
With the Ubuntu 9.04 Beta release, we invite you to install and test the kerneloops package. kerneloops is a daemon that collects kernel crash information and then submits the extracted signature to the kerneloops.org website for statistical analysis and presentation to the Linux kernel developers. Additionally, a bug report regarding the oops in question will also be filed within launchpad for tracking purposes.
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:
Users of Intel i845 or i865 video chipsets are unable to load X, getting an error message of "Fatal server error: Couldn't bind memory for BO front buffer". Investigation of this issue is ongoing. 304871
Ctrl-Alt-Backspace is now disabled, to reduce issues experienced by users who accidentally trigger the key combo. Users who do want this function can enable it in their xorg.conf, or via the command dontzap --disable.
317781 - "Ext4 data loss". This *was* a known issue but should be resolved with the 2.6.28-10.32 kernel. Jaunty Beta should not suffer from this issue.
Reporting bugs
It should come as no surprise that this alpha release of Jaunty Jackalope contains other bugs. Your comments, bug reports, patches and suggestions will help fix bugs and improve future releases. Please report bugs through the Ubuntu bugtracker
