| = Upgrading from Xubuntu 11.04 = | Oneiric Ocelot includes new releases of all the major flavors of Ubuntu: desktop, server, cloud, Kubuntu, Xubuntu, Lubuntu, Edubuntu, Mythbuntu, and Ubuntu Studio. For Ubuntu, this release provides a full Unity experience even without 3D hardware acceleration, promoting Unity 2D to the primary fallback shell. LightDM steps forward as the login manager for Ubuntu, Edubuntu, Xubuntu, Mythbuntu, and Ubuntu Studio, and includes a customized Unity greeter. Kubuntu showcases the best new features of the KDE Platform, Plasma Workspaces, and Applications, including the Muon Software Centre. Ubuntu Server introduces a technical preview of Juju, a thorougly modern approach to service deployment and orchestration on cloud and bare metal, and support for the ARM architecture. |
| Line 12: | Line 13: |
| To upgrade from Xubuntu 11.04 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 '11.10' is available. Click "Upgrade" and follow the on-screen instructions. | ==== Revised Software Center ==== The Ubuntu Software Center adds new "top rated" views to the main category page and all subcategory pages, now allows you to edit or delete your own reviews, and has had a significant speedup for standalone deb file installations (gdebi functionality).

==== 32-bit compatibility on amd64 systems ==== |
| Line 26: | Line 22: |
| = New features since Xubuntu 11.04 = | Ubuntu 11.10 provides "multiarch" support for installing 32-bit library and application packages on 64-bit systems. For all amd64 installs and upgrades, select 32-bit software, including skype and flash, will be installable directly using the same 32-bit packages that are used on i386 installations, without the need to install the {{{ia32-libs}}} compatibility package. For users this means 32-bit libraries will always be available at the same time as their 64-bit counterparts, even in the case of security updates, and users will only need to install those 32-bit libraries needed by the applications they have installed. |
| Line 28: | Line 24: |
| These features are showcased for your attention. Please test them and report any bugs you find: | ==== Linux 3.0 Kernel ==== |
| Line 30: | Line 26: |
| http://help.ubuntu.com/community/ReportingBugs | Ubuntu 11.10 includes the 3.0.0-12.20 Ubuntu kernel which brings the 3.0 upstream kernel, the latest mainline release. The Ubuntu kernel is based on the linux v3.0.4 [[http://kernel.org|upstream stable kernel]]. This kernel update brings a number of performance improvements both to ext4 (the default filesystem) and the process scheduler, which should improve interactive beahviour. It also brings support for newer hardware. For the server the kernel also brings the return of Xen dom0 support as a tech preview building towards full support for the 12.04 LTS. It also has container and namespace improvements enabling full LXC support which is of particular interest on ARM platforms. There are also a number of networking and netfilter improvements. Of note to application developers the default number of file descriptors has been increased simplifying management of programs utilising very large numbers of files. For the deeply technical there are improvements to TCP and fragment identifier generations, BTRFS has a number of significant improvements, ext4 has SMP scalability improvements, and the Big Kernel Lock is dead! |
| Line 33: | Line 37: |
| == Xfce 4.6.1 == | ==== Gcc 4.6 Toolchain ==== |
| Line 35: | Line 39: |
| The [[http://www.xfce.org/about/news?id=22|latest release of Xfce]] is included which contains the newest bugfixes to ensure a smooth desktop experience. | Ubuntu 11.10 includes gcc 4.6 as the default compiler. The toolchain is based 4.6-1-9ubuntu3 version of gcc. Some of the notable changes over the gcc 4.5 compiler include: |
| Line 37: | Line 41: |
| == Multimedia == Xubuntu 11.10 includes the Exaile 0.3.0.x music player to make enjoying podcasts, streaming radio, audio books, and music library easier than ever before. On the go? No problem! Exaile's portable media player device manager lets you take your favorite songs with you. |
'''TODO: work with doko to get summary ?? include bintuils info, what about eglibc and cross compile??''' |
| Line 40: | Line 43: |
| == Power Management == New to Xubuntu 11.10 is the Xfce4 power manager which will replace the Gnome Power Manager on the Xubuntu desktop to provide a more integrated power management experience. |
|
| Line 43: | Line 44: |
| == Desktop Notifications == Be notified both in style and consistency thanks to improved notify-osd integration with the Xfce4 desktop and numerous applications included with the default Xubuntu desktop. |
==== Python 2.7 ==== |
| Line 46: | Line 46: |
| == Upstart == As part of our boot performance work, we have now transitioned to Upstart native jobs, to let users get to their desktop faster after boot. Upstart is written by Scott James Remnant. |
''' TO DO: double check on this and Python 3.0; default earlier/ 2.6 removed. ''' |
| Line 49: | Line 48: |
| == Boot Experience == We've done some work on improving the overall look and feel of booting the system. |
==== network-manager 0.9 ==== |
| Line 52: | Line 50: |
| == Performance == After enjoying a faster and smoother startup, you can also expect faster application load times and reduced memory footprint for a number of your favorite Xfce4 applications thanks to improvements in library linking provided by `ld`'s --as-needed flag. |
The network-manager API has changed compatibility from prior versions. There is now an introspectable version property to help with rsolving conflicts. |
| Line 55: | Line 52: |
| == Linux kernel 2.6.31 == | |
| Line 57: | Line 53: |
| Xubuntu 11.10 includes the 2.6.31-11.36 [[http://kernel.org|kernel]] based on 2.6.31.1. The kernel ships with Kernel Mode Setting enabled for Intel graphics (see below). `linux-restricted-modules` is deprecated in favour of DKMS packages. | === New Features === |
| Line 59: | Line 55: |
| == hal deprecation == | '''gThumb''' is now in the default Xubuntu 11.10 installation, to help users with image transformations and viewing. |
| Line 61: | Line 57: |
| Xubuntu 11.10's underlying technology for power management, laptop hotkeys, and handling of storage devices and cameras maps has moved from "hal" (which is in the process of being deprecated) to "Device``Kit-power", "Device``Kit-disks" and "udev". When testing Xubuntu 9.10, please be alert for regressions in those areas and report any bugs you find. | '''leafpad''' is the new default text editor(was mousepad), and now includes the ability to print. |
| Line 63: | Line 59: |
| == New Intel video driver architecture available for testing == | '''pastebinit''' is now included in Xubuntu 11.10 intallations by default. If you need to use http://paste.ubuntu.com/, you can use pastebinit in terminals to paste directly without copying and pasting the data. |
| Line 65: | Line 61: |
| The Intel video driver has switched from the "EXA" acceleration method to the new "UXA", solving major performance problems of Xubuntu 11.04. Xubuntu 11.10 also features [[https://wiki.ubuntu.com/X/KernelModeSetting|kernel mode setting]] by default on Intel hardware, which reduces boot-time flickering and dramatically speeds up suspend/resume. | '''LightDM''' is the new application that manages logins in Xubuntu 11.10. |
| Line 67: | Line 63: |
| == ext4 by default == | === Updated Applications === |
| Line 69: | Line 65: |
| The new "ext4" filesystem is used by default for new installations with Xubuntu 11.10; of course, other filesystems are still available via the manual partitioner. Existing filesystems will not be upgraded. | '''Onboard''' (the onscreen keyboard) is now included in the default Xubuntu menus, under Accessories. For those who require an onscreen keyboard, this will be much easier to access using only a mouse or touchpad. |
| Line 71: | Line 67: |
| If you have full backups and are confident, you can upgrade an existing ext3 filesystem to ext4 by following directions in the [[http://ext4.wiki.kernel.org/index.php/Ext4_Howto#Converting_an_ext3_filesystem_to_ext4|Ext4 Howto]]. (Note that the comments on that page at the time of writing about Xubuntu's use of vol_id vs. blkid are out of date and are not applicable to Xubuntu 11.10.) Maximum performance will typically only be achieved on new filesystems, not on filesystems that have been upgraded from ext3. | = Installation = |
| Line 73: | Line 69: |
| == GRUB 2 by default == | == Overview == |
| Line 75: | Line 71: |
| GRUB 2 is the default boot loader for new installations with Xubuntu 11.10, replacing the previous GRUB "Legacy" boot loader. Existing systems will not be upgraded to GRUB 2 at this time, as automatically reinstalling the boot loader is an inherently risky operation. | |
| Line 77: | Line 72: |
| If you wish to upgrade your system to GRUB 2, then see the [[KernelTeam/Grub2Testing|GRUB 2 testing]] page for instructions. See also the [[http://grub.enbug.org/Manual|upstream draft manual]]. | == Download == |
| Line 79: | Line 74: |
| Some features are still missing relative to GRUB Legacy. Notable among these are lock/password support, an equivalent of grub-reboot, and Xen handling. | Ubuntu 11.10 images can be downloaded from a location near you: |
| Line 81: | Line 76: |
| == iSCSI installation == | * http://www.ubuntu.com/download (Ubuntu and Ubuntu Server) . |
| Line 83: | Line 78: |
| The iSCSI installation process has been improved, and no longer requires `iscsi=true` as a boot parameter; the installer will offer you the option of logging into iSCSI targets if there are no local disks, or you can select "Configure iSCSI" in the manual partitioner. | In addition they can be found at the following links: |
| Line 85: | Line 80: |
| Putting the root filesystem on iSCSI is now supported. | * http://releases.ubuntu.com/11.10/ (Ubuntu, Ubuntu Server) * http://cloud-images.ubuntu.com/releases/11.10/ (Ubuntu Cloud Images) * http://cdimage.ubuntu.com/releases/11.10/ (Ubuntu DVD, preinstalled ARM images, source) * http://cdimage.ubuntu.com/netboot/11.10/ (Ubuntu Netboot) * http://releases.ubuntu.com/kubuntu/11.10/ (Kubuntu) * http://cdimage.ubuntu.com/kubuntu/releases/11.10/ (Kubuntu DVD) * http://cdimage.ubuntu.com/xubuntu/releases/11.10/ (Xubuntu) * http://cdimage.ubuntu.com/edubuntu/releases/11.10/ (Edubuntu) * http://cdimage.ubuntu.com/ubuntustudio/releases/11.10/ (Ubuntu Studio) * http://cdimage.ubuntu.com/mythbuntu/releases/11.10/ (Mythbuntu) * http://cdimage.ubuntu.com/lubuntu/releases/11.10/ (Lubuntu) |
| Line 87: | Line 92: |
| == AppArmor == | = Upgrading = |
| Line 89: | Line 94: |
| App``Armor in Xubuntu 11.10 features an improved parser that uses cache files, greatly speeding up App``Armor initialisation on boot. App``Armor also now supports 'pux' which, when specified, means a process can transition to an existing profile if one exists or simply run unconfined if one does not. | == Upgrading from Ubuntu 11.04 == |
| Line 91: | Line 96: |
| === New profiles === | To upgrade from Ubuntu 11.04 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 '11.10' is available. Click Upgrade and follow the on-screen instructions. |
| Line 93: | Line 98: |
| In addition to the above changes to App``Armor itself, several profiles were added. Enforcing profiles for ```ntpd```, the Evince document viewer (```evince```), and ```libvirt``` are enabled by default. Complain mode profiles for Dovecot are now available in the ```apparmor-profiles``` package. A new profile is provided for Firefox as well, though it is disabled by default. Users can enable App``Armor sandboxing of their browser by running: {{{ $ sudo aa-enforce /etc/apparmor.d/usr.bin.firefox-3.5 |
To upgrade from Ubuntu 11.04 on a server system: install the {{{update-manager-core}}} package if it is not already installed; launch the upgrade tool with the command {{{sudo do-release-upgrade -d}}}; and follow the on-screen instructions. Note that the server upgrade is now more robust and will utilize GNU screen and automatically re-attach in case of e.g. dropped connection problems. == Upgrading from Other Releases == Users of other Ubuntu releases need to upgrade first to 11.04, and then to 11.10. For further information on upgrading to 11.04, please see the instructions in: https://help.ubuntu.com/community/NattyUpgrades = Known issues = The issues we know about at this point (and some of the workarounds), are documented here so you don't need to spend time reporting these bugs again: == Boot, installation and post-install == * In some cases, booting the live system takes a long time until the desktop starts.

| Line 97: | Line 131: |
| Please see the [[https://wiki.ubuntu.com/SecurityTeam/KnowledgeBase/AppArmorProfiles|SecurityTeam/KnowledgeBase]] for a full listing of readily available profiles in Xubuntu. === Libvirt === Libvirt now contains App``Armor integration when using KVM or QEMU. Libvirtd is configured to launch virtual machines that are confined by uniquely restrictive App``Armor profiles. This feature significantly improves virtualisation in Xubuntu by providing user-space host protection as well as guest isolation. == Uncomplicated Firewall == The [[UbuntuFirewall|Uncomplicated Firewall]] now has support for filtering by interface and egress filtering when using the ```ufw``` command. Documentation for ufw is also improved to help users better utilise the ufw framework and take full advantage of Linux netfilter's power and flexibility. See [[https://wiki.ubuntu.com/UbuntuFirewall#Features|UbuntuFirewall#Features]] for a full list of features. == Non-eXecutable Emulation == [[https://wiki.ubuntu.com/Security/Features#Non-Exec%20Memory|Non-eXecutable (NX) memory protection]], also known as eXecute-Disable (XD), has always been available in Xubuntu for any systems that had the hardware to support it and ran the 64-bit kernel or the 32-bit server kernel. The 32-bit PAE desktop kernel ({{{linux-image-generic-pae}}}) now also provides the PAE mode needed for hardware with the NX CPU feature. For systems that lack NX hardware, the 32-bit kernels now provide an approximation of the NX CPU feature via software emulation that can help block many exploits an attacker might run from stack or heap memory. == Blocking Module Loading == To [[https://wiki.ubuntu.com/Security/Features#Block%20module%20loading|block the loading of any further modules]] after boot (generally for servers with unchanging hardware), the {{{/proc/sys/kernel/modules_disabled}}} one-way sysctl flag now exists to add another layer of protections against attackers loading kernel rootkits. == Position-Independent Executables == Building on the work done in Xubuntu 10.10 and 11.04 to proactively protect Xubuntu from unknown threats by using [[https://wiki.ubuntu.com/CompilerFlags|strict compiler flags]], more applications have been built as [[https://wiki.ubuntu.com/Security/Features#PIE|Position-Independent Executables]] (PIE) to take advantage of the [[https://wiki.ubuntu.com/Security/Features#ASLR|Address Space Layout Randomisation]] (ASLR) available in the Xubuntu kernel. In addition to the growing program list, PIE programs are now also built with the [[https://wiki.ubuntu.com/Security/Features#BIND_NOW|BIND_NOW]] linker flag to take full advantage of the existing [[https://wiki.ubuntu.com/Security/Features#RELRO|RELRO]] linker flag. This results in PIE programs having fewer places in their memory that can be controlled to redirect program flow when an attacker attempts memory-corruption exploits. |

Introduction
The Xubuntu developers are moving quickly to bring you the latest and greatest software the Open Source Community has to offer. This is the Xubuntu 11.10 release.
Release Overview
Oneiric Ocelot includes new releases of all the major flavors of Ubuntu: desktop, server, cloud, Kubuntu, Xubuntu, Lubuntu, Edubuntu, Mythbuntu, and Ubuntu Studio. For Ubuntu, this release provides a full Unity experience even without 3D hardware acceleration, promoting Unity 2D to the primary fallback shell. LightDM steps forward as the login manager for Ubuntu, Edubuntu, Xubuntu, Mythbuntu, and Ubuntu Studio, and includes a customized Unity greeter. Kubuntu showcases the best new features of the KDE Platform, Plasma Workspaces, and Applications, including the Muon Software Centre. Ubuntu Server introduces a technical preview of Juju, a thorougly modern approach to service deployment and orchestration on cloud and bare metal, and support for the ARM architecture.
Revised Software Center
The Ubuntu Software Center adds new "top rated" views to the main category page and all subcategory pages, now allows you to edit or delete your own reviews, and has had a significant speedup for standalone deb file installations (gdebi functionality). Full CJK support is also available. OneConf is now built in to keep your installed applications between computers in sync. You just need to activate it with "File → Sync between computers…".
LightDM now uses the new gtk greeter by default.
Underlying Infrastructure
32-bit compatibility on amd64 systems
Ubuntu 11.10 provides "multiarch" support for installing 32-bit library and application packages on 64-bit systems. For all amd64 installs and upgrades, select 32-bit software, including skype and flash, will be installable directly using the same 32-bit packages that are used on i386 installations, without the need to install the ia32-libs compatibility package. For users this means 32-bit libraries will always be available at the same time as their 64-bit counterparts, even in the case of security updates, and users will only need to install those 32-bit libraries needed by the applications they have installed.
Linux 3.0 Kernel
Ubuntu 11.10 includes the 3.0.0-12.20 Ubuntu kernel which brings the 3.0 upstream kernel, the latest mainline release. The Ubuntu kernel is based on the linux v3.0.4 upstream stable kernel.
This kernel update brings a number of performance improvements both to ext4 (the default filesystem) and the process scheduler, which should improve interactive beahviour. It also brings support for newer hardware.
For the server the kernel also brings the return of Xen dom0 support as a tech preview building towards full support for the 12.04 LTS. It also has container and namespace improvements enabling full LXC support which is of particular interest on ARM platforms. There are also a number of networking and netfilter improvements.
Of note to application developers the default number of file descriptors has been increased simplifying management of programs utilising very large numbers of files.
For the deeply technical there are improvements to TCP and fragment identifier generations, BTRFS has a number of significant improvements, ext4 has SMP scalability improvements, and the Big Kernel Lock is dead!
Gcc 4.6 Toolchain
Ubuntu 11.10 includes gcc 4.6 as the default compiler. The toolchain is based 4.6-1-9ubuntu3 version of gcc. Some of the notable changes over the gcc 4.5 compiler include:
TODO: work with doko to get summary ?? include bintuils info, what about eglibc and cross compile??
Python 2.7
TO DO: double check on this and Python 3.0; default earlier/ 2.6 removed.
network-manager 0.9
The network-manager API has changed compatibility from prior versions. There is now an introspectable version property to help with rsolving conflicts.
New Features
gThumb is now in the default Xubuntu 11.10 installation, to help users with image transformations and viewing.
leafpad is the new default text editor(was mousepad), and now includes the ability to print.
pastebinit is now included in Xubuntu 11.10 intallations by default. If you need to use http://paste.ubuntu.com/, you can use pastebinit in terminals to paste directly without copying and pasting the data.
LightDM is the new application that manages logins in Xubuntu 11.10.
Updated Applications
Onboard (the onscreen keyboard) is now included in the default Xubuntu menus, under Accessories. For those who require an onscreen keyboard, this will be much easier to access using only a mouse or touchpad.

Upgrading
Upgrading from Ubuntu 11.04
To upgrade from Ubuntu 11.04 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 '11.10' is available. Click Upgrade and follow the on-screen instructions.
To upgrade from Ubuntu 11.04 on a server system: install the update-manager-core package if it is not already installed; launch the upgrade tool with the command sudo do-release-upgrade -d; and follow the on-screen instructions. Note that the server upgrade is now more robust and will utilize GNU screen and automatically re-attach in case of e.g. dropped connection problems.
Upgrading from Other Releases
Users of other Ubuntu releases need to upgrade first to 11.04, and then to 11.10.
For further information on upgrading to 11.04, please see the instructions in:
Known issues
The issues we know about at this point (and some of the workarounds), are documented here so you don't need to spend time reporting these bugs again:
Boot, installation and post-install
In some cases, booting the live system takes a long time until the desktop starts. (791139)
When overwriting an existing installation in the Ubiquity desktop installer, it creates a new swap partition instead of re-using the already existing one. (782507)
Ubiquity desktop installer proceeds to use free space without warning, if sufficient free space exists, and "install alongside" is selected, then clicking on the forward button just begins the installation without warning. (766265)
omap3/omap4 netboot images are known to be too small (806751).
The "Memory test" mode is hanging indefinitely without any progress on some systems (confirmed on Dell Mini 10). (856055)
Chinese installs need to use the live environment instead of install only, to be able to type localize character. (871726)
Upgrades
Ubuntu 11.10 has migrated away from /var/run, /var/lock and /dev/shm and now uses /run, /run/lock and /run/shm instead (respectively). While the Ubuntu AppArmor packages and shipped policy have been adjusted for this, custom policy may need to be updated. The following my be used to aid in migration (it allows both the old an the new paths):
$ sed -i -e 's#/var/run#/{,var/}run#' -e 's#/var/lock#/{run,var}/lock#' -e 's#/dev/shm/#/{dev,run}/shm/#' <profile>Ubuntu 11.04 failed to upgrade to 11.10 with gcj-4.4-jre installed (853688)
amd64 users who updated to oneiric prior to August 16th or who installed oneiric prior to Alpha 3 will need to manually enable multiarch support on their systems to ensure they get the same experience (and see the same packages) as other users. This is as simple as running the following command: $ echo foreign-architecture i386 | sudo tee /etc/dpkg/dpkg.cfg.d/multiarch An apt-get update later, and you'll have access to the full array of i386 packages in addition to the amd64 ones.
Any users who have updated to ubuntu 11.10 beta 1 and haven't updated since then, may encounter the fact that 'apt-get update' returns non zero, although it does successfully update the Packages file.

- When using the new plymouth splash screen, occasionally using the desktop cd to install, the message "hit any key to continue" does not appear. Should you get a black screen with text and the sliding throbber, when the throbber stops moving and the cd ejects, remove the cd and hit enter on the keyboard to continue.(Bug:???)
The Bluetooth configuration does not work at the present time in Xubuntu. A workaround is to install 'blueman' to manage bluetooth. (831488)
