-В этих заметках к выпуску приведён обзор релиза Ubuntu 10.10 (Maverick Meerkat) и перечислены известные проблемы Ubuntu 10.10 и её модификаций.
-====== Обзор выпуска 10.10 (Maverick Meerkat) ======
-===== Центр приложений Ubuntu =====
-Центр приложений Ubuntu теперь показывает разделы "Популярные" и "Что нового", историю установки и удаления пакетов, а также позволяет легко находить расширения для приложений. Сейчас доступен для покупки плеер Fluendo DVD, другие приложения также скоро будут доступны для покупки.
-===== Шрифт Ubuntu =====
-Было разработано [[http://font.ubuntu.com/|новое семейство шрифтов Ubuntu]], которое используется для меню пользовательского интерфейса, виджетов и заголовков в Ubuntu и Kubuntu. Оно включает латинские, кириллические и греческие наборы символов в Ubuntu 10.10 с поддержкой обычного, курсивного, полужирного и полужирного курсивного стилей. Эти шрифты также поддерживают новый [[http://en.wikipedia.org/wiki/Indian_rupee_sign|символ индийской рупии]], что делает Ubuntu 10.10 первой операционной системой, поддерживающей новейший символ валюты и готовой для использования [[http://www.kdedevelopers.org/node/4331|миллиардом жителей Индии]] с первым запуском системы.
-Разрабатываемый для улучшения читаемости с экрана и [[http://www.markshuttleworth.com/archives/537|эстетической красоты]] шрифт был впервые показан в дизайне нового логотипа Ubuntu 10.04. Он будет развиваться и далее для поддержки арабского и моноширинного варианта, а также иврита, в последующих выпусках Ubuntu под руководством компании [[http://www.daltonmaag.com|Dalton Maag]], специализирующейся на разработке шрифтов, и [[http://design.canonical.com|команды дизайнеров Ubuntu]].
-===== Программа установки =====
-Программа установки Ubiquity была переработана чтобы быть проще в использовании, а также чтобы предоставить возможность загрузки и установки драйверов и обновлений в процессе установки.
-===== Ubuntu для настольных компьютеров =====
-Базовая платформа [[http://www.gnome.org|GNOME]] обновлена до текущей [[http://library.gnome.org/misc/release-notes/2.32/|версии 2.32]], включая новые API [[http://live.gnome.org/dconf|dconf и gsettings]].
-[[http://projects.gnome.org/evolution/|Evolution]] обновлён до версии 2.30 и теперь работает намного быстрее по сравнению с версией в Ubuntu 10.04 LTS.
-Менеджер фотографий и изображений [[http://f-spot.org/|F-Spot]] заменён на новый - [[http://yorba.org/shotwell/|Shotwell]].
-[[http://gwibber.com/|Gwibber]] также был обновлён и теперь поддерживает новую систему авторизации в [[http://www.twitter.com/|Twitter]], а также была изменёна схема работы хранилища данных для повышения производительности.
-Меню [[https://launchpad.net/indicator-sound|регулятора громкости]] также подверглось изменениям и теперь включает в себя кнопки управления музыкальным проигрывателем.
-В Ubuntu One повышена степень интеграции с системой при помощи нового процесса входа и регистрации, улучшений Nautilus, касающихся параметров синхронизации папок, ускорения синхронизации файлов и возможности делиться ссылками на музыкальные композиции в Ubuntu One Music Store.
-===== Ubuntu для нетбуков =====
-Теперь в Ubuntu Netbook Edition принят по умолчанию новый графический интерфейс [[http://www.markshuttleworth.com/archives/383|Unity]]. Он включает в себя возможности запуска приложений, обзора файлов, семантического поиска с использованием zeitgeist. Пространство по вертикали оптимизировано благодаря общему главному меню и развёртыванию окон приложений на весь экран по умолчанию.
-Также доступна программа запуска программ, которая поможет вам работать с наиболее часто используемыми приложениями. Все элементы главного меню и ярлыки рабочего стола автоматически отображаются в программе при первом запуске Unity.
-Время отображается в панели с помощью нового модуля indicator-datetime, который пока ещё не имеет возможности графической настройки параметров отображения текущей даты. Графический интерфейс настройки индикатора появится в следующей версии Ubuntu  - 11.04.
-Стандартная программа управления фотографиями и изображениями была заменена на [[http://yorba.org/shotwell/|Shotwell]]. Несмотря на это, все преимущества версии Ubuntu для настольных компьютеров доступны также и для пользователей нетбуков. Evolution теперь работает в режиме, оптимизированном для небольших экранов.
-Список требований к аппаратному обеспечению компьютера [[https://wiki.ubuntu.com/DesktopExperienceTeam/UnityHardwareRequirements|доступен здесь]].
-===== Ubuntu для серверов =====
-Мы добавили новую версию Eucalyptus (версия 2.0), которая исправляет большое количество проблем, предоставляет большую стабильность и улучшенное управление пользователями.
-Образы облачных систем Ubuntu теперь могут быть запущены вне среды EC2 или UEC. Это позволит вам быстро и просто протестировать функциональность образа без необходимости запуска нового экземпляра объекта. На [[https://help.ubuntu.com/community/UEC/Images|wiki]] Ubuntu доступна более подробная информация.
-Canonical также запустил программу ''Ubuntu в облачных системах''. У всех есть возможность бесплатно попробовать Ubuntu 10.10 для серверов на Amazon EC2 в течение одного часа. Посетители страницы загрузки теперь могут также выбрать возможность испытания простоты и скорости облачных вычислений и Ubuntu. Для того, чтобы участвовать в программе, перейдите на сайт [[http://10.cloud.ubuntu.com]].
-===== Kubuntu =====
-Kubuntu 10.10 comes with the latest [[http://www.kde.org|KDE]] Software. KDE Platform, Workspaces and Applications were [[http://www.kde.org/announcements/announce-4.5.1.php|updated to 4.5.1]].
-For 10.10, Kubuntu has merged the Desktop and Netbook images into one image featuring both the Plasma Desktop and Plasma Netbook workspaces.  The appropriate workspace for your machine will be launched at login, you can also change the workspace in System Settings.
-Plasma Netbook now sports the Global Menu by default.
-The defaults web browser is now Rekonq, a KDE browser based on Qt Webkit.
-The new KDE bluetooth application collection Bluedevil is now installed by default.
-Pulseaudio is the default sound server to match other Ubuntu variants.
-KPackageKit updates bring a faster backend and an updated UI with an application based view.  It also has new features such as a backup/restore tool for the list of installed packages.
-Kubuntu's installer, Ubiquity, now offers install of restricted packages during the OS install.  Install starts after partitioning making it a quicker experience.
-Qapt-batch now replaces install-package as the update/batch-installer utility
-[[http://qt.nokia.com/products/|Qt]] was updated to the current [[http://labs.qt.nokia.com/2010/09/21/qt-4-7-0-now-available/|4.7]] release and Qt Webkit to 2.0.
-Kubuntu Mobile Tech Preview is a new variant with a workspace suitable for smart phones.
-For more information see the Kubuntu [[http://www.kubuntu.org/news/10.10-release|release page]]
-===== Xubuntu =====
-[[http://www.xfce.org/|Xfce4]] was updated to the current [[http://www.xfce.org/documentation/changelogs/4.6.2?PHPSESSID=01a9340c291d5153df6ecade0e0ce0ad|4.6.2 release]]. This fixes many of the bugs and updates the programs used in Xubuntu.
-New default applications: Parole (Xfce4 Media Player) replaced Totem Movie Player, Xfburn (Xfce4 CD/DVD burning tool) replaced Brassero, and xfce4-taskmanager (Xfce4 process manager) replaced Gnome-Task-Manager.
-===== Edubuntu =====
-Edubuntu features an easier than ever installation for LTSP and netbook users. It also now ships with Gnome Nanny, a tool for restricting computer access to users at certain times that also provides basic content filtering.
-Ubuntu Netbook Remix is now replaced with the Unity interface. LTSP has been updated to 5.2.4 and the Edubuntu menueditor has been updated to fix issues in the previous release.
-Edubuntu also includes now additional wallpapers and language support has now been expanded to 143 languages.
-During this release cycle Edubuntu also got a brand new website and now has presence on the most popular social networking sites.
-===== Ubuntu Studio =====
-Ubuntu Studio has had several applications updated and includes the changes from Ubuntu.  There is now better integration between Pulse Audio and JACK - starting JACK does not automatically suspend Pulse Audio anymore. JACK and Pulse Audio can be used side by side if they are using different audio interfaces, if they are trying to use the same audio interface JACK will take precedent.   In addition,  the network connections can now be configured with gnome-network-admin.
-===== Mythbuntu =====
-В этом релизе Mythbuntu был обновлен [[http://www.mythtv.org/|MythTV]] до версии 0.23.1. Добавлен новый инструмент для резервного копирования и восстановления.
-===== Ядро Linux 2.6.35 =====
-RC includes the 2.6.35-22.33 kernel which is based on the 2.6.35.4 Upstream stable [[http://kernel.org|kernel]].
-This kernel includes additional input subsystem patches for improved multitouch capability, improved support for Intel Sandybridge which includes support for 82579 LOM's, Apparmor bug fixes, reverts some KMS disablement patches, and general security updates ([[http://people.canonical.com/~ubuntu-security/cve/2010/CVE-2010-3081.html|CVE-2010-3081]],[[http://people.canonical.com/~ubuntu-security/cve/2010/CVE-2010-3301.html|CVE-2010-3301]]).  With 10.10 we have also dropped support for i586 and lower processors, as well as i686 processors without cmov support.
-There will be a kernel update made available shortly after the release.
-====== Установка ======
-===== Обзор =====
-The graphical installer has been streamlined and given a substantial visual redesign.  It now only asks the minimum of questions (language and partitioning) before it starts to copy files from the CD, and asks the remaining questions while transferring files to disk.
-The new [[https://btrfs.wiki.kernel.org/index.php/Main_Page|btrfs]] file system may now be used during installation via manual partitioning, as long as `/boot` is on some other file system.
-===== Загрузка выпуска =====

-===== Системные требования =====
-Минимальное количество памяти для Ubuntu 10.10 — 256 Мбайт. Учтите, что если вы используете встроенную видеокарту, то часть памяти уйдёт на обеспечение её работы. Если на вашем компьютере лишь необходимый минимум памяти, то установка займёт больше времени, чем обычно. Тем не менее, система установится и будет нормально работать.
-В системе с меньшим количеством памяти в меню загрузки можно выбрать "Установка Ubuntu". чтобы загрузить один инсталлер, а не всю систему. Или можно попробовать другие диски.
-====== Обновление ======
-Подробные инструкции по обновлению доступны на [[http://www.ubuntu.com/getubuntu/upgrading|данной странице]] в сети.
-===== С версии Ubuntu 10.04 LTS  =====
-To upgrade from Ubuntu 10.04 LTS on a desktop system, press Alt+F2 and type in ''update-manager -d'' into the command box. Update Manager should open up and tell you: New distribution release '10.10' is available. Click Upgrade and follow the on-screen instructions.
-To upgrade from Ubuntu 10.04 LTS 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 -d''; and follow the on-screen instructions.
-===== С версии Kubuntu 10.04 LTS =====
-To upgrade from Kubuntu 10.04 LTS, please follow the [[https://help.ubuntu.com/community/MaverickUpgrades/Kubuntu|upgrade instructions]].
-===== С других выпусков Ubuntu =====
-Users of other Ubuntu releases need to upgrade first to 10.04LTS, and then to 10.10.
-====== Известные проблемы ======
-===== Загрузка, установка, обновление и послеустановочный период =====
-  * **At end of installation, when the system goes to reboot, the CD-ROM is ejected and throws up lots of errors: "end_request: I/O error, dev sr0, sector 437628"**. Pressing Enter will reboot and resume normally. These errors are harmless and can be ignored. (Bug:539027)
-  * **In dual boot installs, after using Windows applications that use the [[http://en.wikipedia.org/wiki/Flexnet|FlexNet Publisher]], as a license manager, such software will overwrite GRUB, effectively breaking the boot process.** This has been fixed for applications including Adobe Photoshop (CS4), Dell Datasafe backup,  Autocad 2009, Adobe Flash Builder 4, UltraISO. If you have this problem with a new application, see the bug report to add its signature to prevent future problems (Bug:441941)
-  * **The Wubi Windows installer was reported to be unable to open Windows' boot configuration data store in some (but not all) cases.**  Investigation of the problems are ongoing (Bug:613288)
-  * **You cannot upgrade if wubi is installed to a partition other than Windows.** (Bug:610898,Bug:653134)
-  * **Lenovo S10-3 systems don't boot.** Temporary workaround: add "intel_idle.max_cstate=0" as a kernel paremeter at boot (Bug:634702). A fix already exists that will be available only at release time (Bug:647071).
-  * **Macbook's with EFI will not be able to boot the 64bit (amd64) version of Ubuntu 10.10 live cd.** The i386 CDs will work. (Bug:633983)
-  * **When the XHCI module is loaded for USB 3.0 operation the system cannot suspend.** Manually unloading XHCI will allow suspend to complete normally.  To avoid future suspend problems, the workaround is to add ''SUSPEND_MODULES="xhci-hcd"'' to ''/etc/pm/config.d/unload_module'' then the system can suspend normally. (Bug:522998)
-  * **Hibernation may be unavailable with automatic partitioning.** The default partitioning recipe in the installer will in some cases allocate a swap partition that is smaller than the physical memory in the system.  This will prevent the use of hibernation (suspend-to-disk) because the system image will not fit in the swap partition.  If you intend to use hibernation with your system, you should ensure that the swap partition's size is at least as large as the system's physical RAM. (Bug:345126)
-  * **I/O error after CD is ejected at end of install.**  In some cases, ejecting the CD at the end of installation will leave errors on the screen such as:
-''
-end_request: I/O error, dev sr0, sector 437628
-''
-these error messages indicate that the system is still trying to access some files on the CD, and are harmless except that they obscure the message asking the user to press Enter to reboot.  You can safely remove the CD from the tray and press Enter at this point to reboot to your new Ubuntu system. (Bug:539027)
-  * **Upstart jobs cannot be run in a chroot.** Upstart jobs cannot be started in a chroot because upstart acts as a service supervisor, and processes within the chroot are unable to communicate with the upstart running outside of the chroot (Bug:430224).  This will cause some packages that have been converted to use upstart jobs instead of init scripts to fail to upgrade within a chroot.  Users are advised to configure their chroots with /sbin/initctl pointing to /bin/true, with the following commands run within the chroot:
-''
-dpkg-divert --local --rename --add /sbin/initctl
-ln -s /bin/true /sbin/initctl
-''
-  * **The version of upstart included since Ubuntu 9.10 no longer uses the configuration files in the /etc/event.d directory, looking to /etc/init instead.** No automatic migration of changes to /etc/event.d is possible. If you have modified any settings in this directory, you will need to reapply them to /etc/init in the new configuration format by hand. (Bug:402759)
-===== Файловые системы =====
-  * **Performance regressions with ext4 under certain workloads.**  The default file system for installations of Ubuntu 10.10 is `ext4`, the latest version in the popular series of Linux extended file systems.  `ext4` includes a number of performance tuning changes relative to previous versions such as `ext3`, the file system used by default up to Ubuntu 9.04.  These generally produce improvements, but some particular workloads are known to be significantly slower when using `ext4` than when using `ext3`.  If you have performance-sensitive applications, we recommend that you run benchmarks using multiple file systems in your environment and select the most appropriate.
-  * **Use of degraded RAID 1 array may cause data loss in exceptional cases.**  If each member of a RAID 1 array is separately brought up in degraded mode across subsequent runs of the array with no reassembly in between, there is a risk that the disks will be reported as in sync when they are not, resulting in data loss due to inconsistencies between the data that has been written to each member. This is an unlikely occurrence during normal operations, but admins of systems using RAID 1 arrays should take care during maintenance to avoid this situation. (Bug:557429)
-  * **Avahi will always start even if a .local domain is present.**  The ''avahi-daemon'' package, which implements the mDNS "zeroconf" standard, formerly included a check to avoid running when a conflicting ''.local'' DNS domain is present, as it was reported that some ISPs advertise such a ''.local'' domain on their networks, leaving Ubuntu hosts unable to see names advertised on the local network (Bug:327362).  In Ubuntu 9.10, ''avahi-daemon'' is started regardless.  It is possible that this may cause other problems.  If your network is configured this way, you can disable mDNS using the following command:
-''
-sudo stop avahi-daemon
-sudo sed -e '/^start/,+1s/^/#/' /etc/init/avahi-daemon.conf
-''
-  * **NSS resolution breaks with LDAP over SSL in Ubuntu Server.**  Upgrading systems configured to use LDAP via SSL as the first service in the NSS stack (in /etc/nsswitch.conf) leads to broken NSS resolution afterwards such that `setuid` applications like `sudo` would stop working.  To work around this, switch to the libnss-ldapd package instead of libnss-ldap before the upgrade, or use nscd. (Bug:423252)
-  * **Cryptsetup is not by default compatible with the version in 10.04LTS.**  An encrypted disk set up under 10.04LTS will fail to properly mount under maverick. This is because, as documented in the ''/usr/share/doc/cryptsetup/NEWS.Debian.gz'', defaults have changed. So to mount a disk which was created in 10.04LTS with cryptsetup, in 10.10 you must specify the cipher as such: ''cryptsetup -c aes-cbc-plain create h /dev/sdb1''  (Bug:622762)
-===== Графика и отображение =====
-  * **Connected DisplayPort monitors may prevent booting when using the nouveau video driver.** (Bug:655795)
-  * **External monitor connected via DisplayPort is not recognized when using the nouveau driver.** (Bug:655800)
-  * **Image distortion (vsync) on some AMD ATI cards with the proprietary drivers**. (Bug:303697)
-  * **The new Xorg 1.9 available in Maverick is not compatible with nVidia based chipsets that use the (nvidia-96) and (nvidia-173) drivers.** (Bug:626974)
-  * **The logo will not display during boot when using the Nvidia proprietary driver.** (Bug:653274)
-  * **The wrong display port is chosen during install of Apple iMacs (Core i5).** If you plug a second screen on the mini display port, you can install ubuntu normally using this 2nd screen. (Bug:542660)
-  * **Non-mirrored dual-screen setups may provide incorrect display on secondary monitor.** (Bug:619663)
-===== Сеть & Wi-Fi =====
-  * **802.11n support for the iwlagn driver has been temporarily disabled.** Intel is actively working to get this properly fixed up in the firmware. This workaround should be reverted once updated firmware is available. (Bug:630748)
-  * **"Additional drivers" proposes b43, but the installation fails with "Not supported low-power chip"**. This affects some Dell Mini 9 models and potentially any system with BCM4312 adapters.(Bug:655111)
-  * **Ubuntu 10.10 does not  support the XDMCP protocol for remote graphical logins.** Users who require XDMCP support will need to install another display manager, such  as wdm or xdm, for this functionality (Bug:408417).
-  * **New drivers preventing "sleep" problem for RTL8111/8168B gigabit network adapter (usually onboard) are missing.** (Bug:573259)
-===== Устройства ввода =====
-  * **Some fingerprint readers normally supported by fprint are not fully supported yet.** Installing fprint from the latest PPA may work (Bug:640083, Bug:657017, Bug:657031). See [[https://bugs.edge.launchpad.net/ubuntu/+source/libfprint|the current bug list for libfprint0]] to see if your device is affected and possible workarounds.
-===== Общее в настольной версии =====
-  * **When running on battery, clicking on the battery icon permanently says "Battery life (estimating...)".** This affects some HP, Compaq, Dell and System76 systems (Bug:629258).
-  * **Resizing windows with the Ambiance theme by grabbing window borders is difficult.** This can be mitigated by switching to the Dust or Clear Looks theme (Bug:160311).
-  * **Several panel applets may be displayed twice or overlap.** (Bug:439448).
-===== Общие настольные приложение =====
-  * **It is not possible to create Ubuntu 10.04 USB disks from the Startup Disk Creator in Ubuntu 10.10 due to a backwards incompatibility in the syslinux program.**
-  * **Adobe Air is not available for 64-bit.**
-  * **GDM does not support XDMCP.** The version of ''gdm'' included in Ubuntu 10.10 does not support the XDMCP protocol for remote graphical logins.  Users who require XDMCP support will need to install another display manager, such as ''wdm'' or ''xdm'', for this functionality. (Bug:408417)
-  * **When uploading a file to a website, the file browse window doesn't show a preview when an image is selected.** This only happens on some websites, when Flash is installed. It appears such websites replace the Nautilus "Browse" dialog with a Flash version (Bug:613886).
-  * **The Gwibber micro-blogging client no longer permits synching of account details across computers.**  The client was switched to SQLite for back end  storage and to make it faster, but means that syncing of account details across computers is no longer supported.
-  * **The Cheese webcam application has video recording related performance regressions.** (Bug:610600)
-  * **The Nautilus file manager application will sometimes create a non-existent device after the mount and umount of a device.** (Bug:548546)
-===== Ubuntu для серверов =====
-  * **As a security improvement, libvirt in Maverick runs kvm with limited rights.** This disables the possibility of displaying a local SDL window (Bug:615077). Users are advised to use the VNC support instead.
-  * **If you configure apache to use a password-protected SSL key, you cannot specify the key passphrase at boot-time.** To work around this, Apache needs to be started manually after boot (Bug:582963)
-  * **libdbi 0.8.3 has a known ABI incompatibility with earlier versions of libdbi that have been distributed with past versions of Ubuntu and Debian.** As such, any third-party software linked against libdbi.so.0 may give unexpected results if they utilize the 'dbi_error_flag' enum. Recompiling these applications will resolve this issue. (Bug:625882)
-  * **Previous libvirt versions would probe a qemu disk to determine its format and did not require that the format be declared in the XML.** This is considered a security problem in most deployments and newer versions of libvirt will default to the 'raw' format when the format is not specified in the XML. As a result, non-raw disks without a specified disk format will no longer be available in existing virtual machines. The libvirt-migrate-qemu-disks tool is provided to aid in transitioning virtual machine definitions to the new required format. In essence, it will check all domains for affected virtual machines, probe the affected disks and update the domain definition accordingly. This command will be run automatically on upgrade. For new virtual machines using non-raw images, the disk format must be specified in the domain XML provided to libvirt, otherwise the disk will not be available to the virtual machine. See ''man 1 libvirt-migrate-qemu-disks'' for details. Users who require the old behavior can adjust the 'allow_disk_format_probing' option in /etc/libvirt/qemu.conf.
-===== Ubuntu для нетбуков (UNE) =====
-  * **UNE needs graphical driver acceleration to be able to run.**  Otherwise, you should be warned about missing them and will be logout and proposed to run standard ubuntu desktop session.
-  * **The targeted netbooks were intel GPU graphic mainly and was heavily tested on nvidia as well.**  You may encounter visual glitches, and Unity may not work altogether on some ATI cards.
-  * **Newly installed UNE 10.10 does not have a guest session.** (Bug:657371)
-  * **Certain applications such as Firefox and Shotwell do not use the global menu.  Certain applications such as Glade may not be functioning properly with the global menu.**
-===== ARM =====
-  *A separate page has been made available with release notes for the developer-oriented Ubuntu 10.10 armel port.  Please see [[https://wiki.ubuntu.com/ARM/MaverickReleaseNotes]] for information about issues affecting installation on specific ARM boards.
-  * **Users upgrading beagle (armel omap) from lucid (10.04 LTS) to maverick (10.10) can run out of free space if USB drive is 4G or less.**
-  * **After installing the system on the Dove architecture, you may see many a text screen with errors that say "end_request: I/O error".** However, this has not seemed to cause any installs to fail. Pressing 'enter' on this screen will reboot the system, but a message should have been displayed here warning you to remove the install media first. (Bug:539027)
-  * **Cannot suspend Ubuntu ARM images for Panda Boards(OMAP4).** Due to current hardware limitations it is not possible to use suspend on the Ubuntu ARM images for the Panda Boards(OMAP4) even though the suspend option is shown in the logout menu.  (Bug:628029)
-  * **Sound is not working on the Dove A0 boards, OMAP3 Beagleboards, and OMAP4 Panda boards.** (Bug:644028, Bug:651302, Bug:637947)
-  * **On Dove X0 based hardware, if you have speakers or headphones plugged into the headphone jack on the board, you will need to make some adjustments to hear audio.** Under sound preferences, click the "Output" tab and select "Analog Headphones" for the connector. (Bug:551249)
-===== Kubuntu =====
-  * **In many cases desktop effects are not active by default or on login in Kubuntu even for systems with video systems that support the current default effects well.** These can be manually enabled in SystemSettings -> Desktop Effects, but in order to continue to have effects enabled on login, it is necessary to disable hardware checks in the advanced tab of desktop effect settings. Before bypassing these check, do verify that your system is working correctly with effects enabled. (Bug:628930)
-  * **On some Kubuntu systems, the display server crashes on logout instead of returning to the KDE Display Manger (KDM) login display.** For systems with this problem, the problem can be avoided by changing the method KDM uses to interact with the display server. Edit /etc/kde4/kdm/kdmrc and uncomment the line "#TerminateServer=true" by changing it to "TerminateServer=true" and restart KDM (reboot the system or sudo restart kdm). (Bug:651294)
-  * **The Global Menu may not show gtk applications' menus.** You will need to install the package ''appmenu-gtk''.
-  * **Updates not downloaded during install when selected and internet is available during install** the can be downloaded after install through the normal update method (Bug: 634664)
-  * **Ubiquity not removed after OEM install** This makes the favourites in Plasma Netbook show the installer after the user setup (Bug: 651086)
-  * **KDevelop crashes** Fix will be released soon, or use the new Beta packages [[http://www.kubuntu.org/news/kdevelop-41-rc-and-koffice-23-beta-1-packaged|the new Beta packages]] or update to [[http://www.kubuntu.org/news/kde-sc-4.5.2|KDE Platform 4.5.2]] (Bug: 656195)
-  * **Dist Upgrade tool does not allow viewing conffile changes** this causes a Qt plugin to get loaded which can crash the upgrade tool if Qt has already been upgraded.  You can view the changes manually on the command line with ''diff -u <filename> <filename>.dpkg-new''  (Bug: 656876)
-===== Mythbuntu =====
-  * Во время установки на оборудование KMS, фон может быть нестабилен.
-  * На данный момент исправить эту ошибку не представляется возможным до окончания установки.
-===== Edubuntu =====
