[分享]Impending Alpha 4 Release

#1

帖子 yoyu007 » 2008-01-30 16:23

Fellow testers,

As per the pre-release announcement, Main is in "soft freeze" for the release of Alpha 4, which is set for January 31st. This is posted in an effort to address some questions and misunderstandings that recur at just about every milestone release.

* The release is set roughly for January 31st in the release schedule, but it may not happen on that exact date. A number of bugs are set as blocking the release, which means that the release will not be made before these bugs are fixed, which in turn explains the possible delay. Just wait for the announcement.

* Any Ubuntu release (alpha, beta, RC, final) is not released until the release team announces it on the ubuntu-devel-announce mailing list. That https://ubuntu.com/Testing has been updated and links to ISO images are available does not mean that the release has been made. It only means that the website editors, who work in different timezones than the release team, and in certain parts of the day, have put the pages online, and that can happen a while before actual release.

Downloading release images prematurely usually makes it harder for mirrors to sync up and uploads to complete, and can delay the release. You'll also most likely be downloading an incomplete, broken image.

Do not download Alpha 4, or any other release, before the release announcement is made. If you aren't subscribed to the list, you can check for it in the list's archive.

* If you have any information to add to the bugs that are blocking Alpha 4, be fast in doing so, and refrain from posting comments that don't add any new information that will help fix the bugs.

* You do not have to download Alpha 4 from scratch if you already have a working Hardy. You'll get an identical set of packages by upgrading your existing test installation.

* If you'd like to learn more on how exactly a milestone release is made, https://wiki.ubuntu.com/MilestoneProcess lists the steps taken in the process.

Xorg 7.3

The latest Xorg is available in Hardy, Xorg 7.3, with an emphasis on better autoconfiguration with a minimal configuration file.
Linux kernel 2.6.24

Alpha 4 includes the 2.6.24-5.8 (2.6.24-rc8-based) kernel. This brings in significant enhancements and fixes that have been merged in the last few months into the mainline kernel. Among these is the introduction of dynticks support for amd64, bringing the same power savings already available on 32-bit systems to 64-bit laptops and desktops.
PulseAudio

Alpha 4 includes [WWW] PulseAudio enabled by default. Some non-GNOME applications still need to be changed to output to pulse/esd by default and the volume control tools are still not integrated. [WWW] https://blueprints.launchpad.net/ubuntu ... dio-jumble
PolicyKit

With Alpha 4, PolicyKit integration is visible in the administrative user interfaces. PolicyKit makes it possible to run administrative applications as a normal user, and have them get a particular set of extra privileges for certain operations, which allows fine-grained control over user permissions and enhances usability, as well as eliminating the security implications of running the whole application as root.

Firefox 3 Beta 2

The latest Firefox 3 beta is packaged in the repositories, bringing much better system integration including theming that mirrors the system such as icons and colours as well as having GTK2 form buttons and open dialog.

Transmission

The GTK version of the popular Transmission BitTorrent client comes with Alpha 4. It's set to replace the Gnome BitTorrent downloader

Vinagre

The new Vinagre VNC client, which is set to replace xvnc4viewer, is installed by default in Alpha 4.

Brasero

The Brasero CD/DVD burning application, which will complement the CD/DVD burning functions of Nautilus and replace the Serpentine audio CD burning utility, is installed by default in Alpha 4.

World Clock Applet

Integrating the features of the intlclock applet, the GNOME panel clock in Alpha 4 can display the time and weather in multiple locations.

GVFS

Nautilus 2.21.6 in Alpha 4 uses GVFS, the virtual filesystem abstraction layer that's set to replace the aging GnomeVFS in GNOME 2.22, as its backend. In the near future, GVFS will make it possible to fix shortcomings of Nautilus such as the inability to restore files from trash, pause and undo file operations, and make it possible to escalate user privileges for certain operations using PolicyKit for authentication. It also brings a significant performance boost to many operations.

GNOME System Monitor

The GNOME System Monitor has a revamped "Resources" tab, with Cairo graphs that scroll and scale smoothly, and brand new widgets.

Virtualization

*

KVM is now officially maintained within in the Ubuntu kernel.
*

libvirt and virt-manager have been adapted to Ubuntu. They allow for easy guest creation and basic management out of the box. Virt-manager can be used to remotely administer guests on a remote server. They also work with XEN, even though it is not officially maintained.
*

The kernel also includes the virtio modifications which should greatly improve guest I/O access.

some known bugs

#3

帖子 yoyu007 » 2008-01-30 16:52

#

The new kernel in Alpha 4 is unable to access CD-ROM devices in some configurations, which means some users who were previously able to install Ubuntu will not be able to install this alpha from CD media. Investigation is ongoing; no workaround is known at this time. [WWW] https://launchpad.net/bugs/181561
#

Video problems have been reported with the 64-bit (amd64) version of Edubuntu desktop. As a workaround, users can manually specify a video resolution at the boot menu. [WWW] https://launchpad.net/bugs/173130
#

Users with an older ATI Radeon graphics card might have video problems. As a workaround, you can boot the livecd with a failsafe mode, and after installation add 'Option "AGPMode" "4"' to the "Device" -section of your /etc/X11/xorg.conf. [WWW] https://launchpad.net/bugs/180343
#

Due to the switch to GVFS, which is not feature complete, the "Network" item in the Places menu doesn't work, and Nautilus can behave erratically, especially in trash operations. Refrain from operating on valuable files with this version

GVFS还不稳定,我被它害惨了,大家最好是不要用清空回收站功能,有可能会删除你其它的文件。 建议工作用电脑(特别是有重要文件)现在最好不要装8.04,如果你要做小白,千万记住要先备份。否则后悔莫及 :em19
