8.10 Technical Overview | Ubuntu
واترككم مع باقي التفاصيل باللغة الانجليزية
GNOME 2.24
Ubuntu brings you the newest GNOME 2.24 desktop environment with tons of bug-fixes and new features, some of which include:
Nautilus file manager has tab support (by Christian Neumair) and Eject icons for removable drives in Places sidebar (by Stefano Teso, Cosimo Cecchi, Christian Neumair, and others).
File Roller archive manager now supports ALZ, RZIP, CAB, TAR.7Z file types also (by Paolo Bacchilega and Changwoo Ryu).
X.Org 7.4
X.Org 7.4, the latest stable version of X.Org, is available in Intrepid. This release brings much better support for hot-pluggable input devices such as tablets, keyboards, and mice. At the same time this will allow the great majority of users to run without a /etc/X11/xorg.conf file. A new failsafe X is introduced, to give better tools for troubleshooting X startup failures.
The fglrx and two of the older nvidia binary drivers are not available for X.Org 7.4 yet, so users of these drivers will be automatically switched to the corresponding open source drivers.
Linux kernel 2.6.27
Ubuntu 8.10 Beta includes Linux kernel 2.6.27, a significant release with better hardware support and numerous bug-fixes.
Encrypted private directory
The ecryptfs-utils package was recently promoted to Ubuntu main, with support for an secret encrypted folder in your Home Folder (by Michael Halcrow, Dustin Kirkland, and Daniel Baumann).
You can help test this new feature by going to Applications → Accessories → Terminal and typing:
sudo aptitude install ecryptfs-utils
ecryptfs-setup-private
Guest session
The User Switcher panel applet (package fast-user-switch-applet) now provides an extra entry for starting a Guest session (by Martin Pitt). This creates a temporary password-less user account with restricted privileges: the account cannot access any users' home directories, nor permanently store data. This is sufficiently safe to lend your laptop to someone else for a quick email check.
Network Manager 0.7
Ubuntu 8.10 Beta ships Network Manager 0.7 (by Dan Williams and others), which comes with long-expected features, such as:
system wide settings (i.e., no need to log in in order to get a connection)
management of 3G connections (GSM/CDMA)
management of multiple active devices at once
management of PPP and PPPOE connections
management of devices with static IP configurations
route management for devices
More information can be found on the Network Manager wiki.
"Last successful boot" recovery entry
On each successful boot, Ubuntu 8.10 will retain a copy of your running kernel and make it available from the boot loader as a "Last successful boot" option (by Ben Collins). This makes it possible for old kernel packages to be safely auto-removed by the package manager, instead of being kept indefinitely.
DKMS
DKMS (by Dell) is included in Ubuntu 8.10, allowing kernel drivers to be automatically rebuilt when new kernels are released. This makes it possible for kernel package updates to be made available immediately without waiting for rebuilds of driver packages, and without third-party driver packages becoming out of date when installing these kernel updates.
Samba 3.2
A lot of new features have been added in Samba 3.2 amongst them:
clustered file server support
encrypted network transport
ipv6 support
better integration with the latest version of Microsoft Windows™ clients and servers.
PAM authentication framework
Ubuntu 8.10 Beta features a new pam-auth-update tool, which allows simple management of PAM authentication configuration for both desktops and servers (by Steve Langasek). Packages providing PAM modules will be configured automatically, and users can adjust their authentication preferences by running sudo pam-auth-update.
More information can be found in the Ubuntu wiki.
Totem BBC plugin
Ubuntu 8.10 Beta features a new plugin for the Totem movie player that fetches free digital content from the BBC. To enable it, start Totem (Applications -> Sound & Video -> Movie Player), enable the plugin (Edit -> Plugins -> BBC content viewer) and select "BBC" from the drop-down labelled "Playlist". The feed is fetched from a staging server at the moment so there may be a delay while it is downloaded.
Thanks to the BBC and Collabora for their work developing this feature.
Known Issues
There are several known bugs that users may run into with Ubuntu 8.10 Beta. We have documented them here for your convenience along with any known workarounds.
A problem that could result in corruption of the firmware on Intel GigE ethernet hardware has led to the disabling of the e1000e driver in the Linux kernel included in Ubuntu 8.10 Beta. Ethernet devices that use this driver cannot be used with Ubuntu 8.10 Beta; support for this hardware will be re-enabled in daily builds immediately after Beta and this issue will be resolved for the Ubuntu 8.10 final release. https://bugs.launchpad.net/bugs/263555
Clicking on links in GNOME programs, such as evolution, will not launch firefox automatically due to a bug in a wrapper script used by the firefox-3.0 package. As a workaround, users can launch firefox manually and copy and paste links into the location bar. https://bugs.launchpad.net/bugs/275410
NetworkManager 0.7 as included in Ubuntu 8.10 Beta is not compatible with static network configuration in /etc/network/interfaces. New installations are not affected by this issue because NetworkManager will manage all interfaces by default. Users upgrading from previous Ubuntu releases can work around this issue by disabling NetworkManager at startup. https://bugs.launchpad.net/bugs/256054
When using the Kubuntu LiveCD, the ubiquity installer hangs at the end of the installation instead of prompting you to reboot. Investigation of this issue is ongoing; as a workaround, you can safely reboot to the new system by hand. https://bugs.launchpad.net/bugs/270423
Installing an LTSP server fails with Ubuntu 8.10 beta because the CD is not recognized as an apt source. This will be resolved for the final release. https://bugs.launchpad.net/bugs/276349
