These release notes document known issues with Ubuntu 8.10 and its variants.
Line 5: Line 7:
The minimum memory requirement for Ubuntu 8.04 is 384MB of memory for desktop CDs, and 256MB for other installation methods. (Note that some of your system's memory may be unavailable due to being used for the graphics card.) The minimum memory requirement for Ubuntu 8.10 is 256 MiB of memory. (Note that some of your system's memory may be unavailable due to being used for the graphics card.)
Line 7: Line 9:
With only the minimum amount of memory available, the installation process will take longer than normal, but will complete successfully, and the system will perform adequately once installed. Low-memory systems may be able to use the desktop CD to install by adding the `only-ubiquity` boot option to run just the installer rather than the whole desktop. With only the minimum amount of memory available, the installation process will take longer than normal, but will complete successfully, and the system will perform adequately once installed. Low-memory systems may be able to use the desktop CD to install by selecting "Install Ubuntu" from the boot menu to run just the installer, rather than the whole desktop started by selecting "Try Ubuntu without any change to your computer".

== iSCSI partitions ==

 * The open-iscsi package is now a maintained option in Ubuntu 8.04 LTS, and iSCSI NAS partitions can be configured right from the installer. At this time, however, the root and boot filesystems should be placed on a local partition, with /usr on the same filesystem as root.

== Route metrics == == ATI video support ==
Line 21: Line 19:
 * ifupdown now sets the default route metric to 100 for interfaces with no metric option set in /etc/network/interfaces. This change makes no difference for most users, but may affect a few users with complex networking requirements. If you rely on the previous default route metric of 0 (zero), edit /etc/network/interfaces and set the metric option explicitly for your interface, for example: {{{
iface eth0 inet static
        address 192.168.0.2
        network 192.168.0.0
        broadcast 192.168.0.255
        netmask 255.255.255.0
        gateway 192.168.0.1
        metric 0
}}}
The proprietary {{{fglrx}}} video driver available in Ubuntu 8.04 LTS and earlier releases is not compatible with the X.Org included in Ubuntu 8.10. Users who used the {{{fglrx}}} driver in Ubuntu 8.04 LTS will on upgrade be moved to the free {{{ati}}} driver instead. This will result in decreased 3D acceleration support on some hardware, but should otherwise be usable.
Line 31: Line 21:
== Network Manager == == nVidia "legacy" video support ==
Line 33: Line 23:
 * In Ubuntu 8.04, network-manager only manages interfaces that are marked for roaming. Thus, all interfaces that were previously managed by network-manager will be set to roaming mode during upgrade. Technically, this takes any interface stanzas using the `dhcp` method with no options and that are marked `auto`, and removes them from /etc/network/interfaces. If you rely on your interfaces being started by ifupdown when the system starts up, you need to re-enable them in /etc/network/interfaces manually, or disable roaming in '''System''' -> '''Administration''' -> '''Network'''. The 71 and 96 series of proprietary nVidia drivers, as provided by the {{{nvidia-glx-legacy}}} and {{{nvidia-glx}}} packages in Ubuntu 8.04, are not compatible with the X.Org included in Ubuntu 8.10. Users with the nVidia TNT, TNT2, TNT Ultra, Ge``Force, Ge``Force2, and Ge``Force4 chipsets are affected and will be transitioned on upgrade to the free {{{nv}}} driver instead. This driver does not support 3D acceleration.
Line 35: Line 25:
== NFS mount support == Users of other nVidia chipsets that are supported by the 173 or 177 driver series will be transitioned to the {{{nvidia-glx-173}}} or {{{nvidia-glx-177}}} package instead.
Line 37: Line 27:
 * To mount NFS filesystems, you must now install the `nfs-common` package. == X.Org Input Devices ==
Line 39: Line 29:
== UltraSPARC disk label changes == The X.Org configuration file ({{{/etc/X11/xorg.conf}}}) still has Input``Device entries for the mouse and keyboard, but they are ignored now because input-hotplug is
used. The keyboard settings now come from {{{/etc/default/console-setup}}}; to change them please use `sudo dpkg-reconfigure console-setup`. After that, HAL and X
need to be restarted (e.g., by rebooting your system).
Line 41: Line 33:
 * Users upgrading to Ubuntu 8.04 LTS on UltraSPARC from Ubuntu 6.06 LTS should manually re-run fdisk on all disks. fdisk will warn if the disk label needs to be updated; follow its instructions. New installations of Ubuntu 8.04 will automatically use the new disk label format. == X.Org evdev xmodmap incompatibility ==
Line 43: Line 35:
= Other known bugs = The X keycodes generated with the new {{{evdev}}} input driver in X.Org 1.5 are not compatible with those generated in Ubuntu 8.04 LTS and before. If you have configured keybindings for your user with a {{{~/.Xmodmap}}} file, you will need to convert or disable it by hand on upgrade.

== GNOME Logout Applet ==

The "Logout" applet which appeared by default on the panel in earlier Ubuntu releases no longer offers the shutdown/reboot/hibernate/suspend actions. It is recommended that you remove this applet and replace it with the "User Switcher" applet, which now combines the previous "User switcher" and "Logout" applets. This change is not yet done automatically on upgrade (https://bugs.launchpad.net/bugs/274146)

== UbuntuStudio real-time kernel support ==

No real-time kernel variant is available for the Linux 2.6.27 kernel included with Ubuntu 8.10. Users of Ubuntu``Studio 8.04 who need real-time kernel support are advised not to upgrade to Ubuntu``Studio 8.10.

These release notes document known issues with Ubuntu 8.10 and its variants.

System Requirements

The minimum memory requirement for Ubuntu 8.10 is 256 MiB of memory. (Note that some of your system's memory may be unavailable due to being used for the graphics card.)

With only the minimum amount of memory available, the installation process will take longer than normal, but will complete successfully, and the system will perform adequately once installed. Low-memory systems may be able to use the desktop CD to install by selecting "Install Ubuntu" from the boot menu to run just the installer, rather than the whole desktop started by selecting "Try Ubuntu without any change to your computer".

Installation

Upgrading

Users of Ubuntu 8.04 can upgrade to Ubuntu 8.10 by a convenient automated process. Users of older Ubuntu releases need to upgrade to Ubuntu 8.04 LTS first, and then to 8.10. Complete instructions may be found at http://www.ubuntu.com/getubuntu/upgrading.

ATI video support

The proprietary fglrx video driver available in Ubuntu 8.04 LTS and earlier releases is not compatible with the X.Org included in Ubuntu 8.10. Users who used the fglrx driver in Ubuntu 8.04 LTS will on upgrade be moved to the free ati driver instead. This will result in decreased 3D acceleration support on some hardware, but should otherwise be usable.

nVidia "legacy" video support

The 71 and 96 series of proprietary nVidia drivers, as provided by the nvidia-glx-legacy and nvidia-glx packages in Ubuntu 8.04, are not compatible with the X.Org included in Ubuntu 8.10. Users with the nVidia TNT, TNT2, TNT Ultra, GeForce, GeForce2, and GeForce4 chipsets are affected and will be transitioned on upgrade to the free nv driver instead. This driver does not support 3D acceleration.

Users of other nVidia chipsets that are supported by the 173 or 177 driver series will be transitioned to the nvidia-glx-173 or nvidia-glx-177 package instead.

X.Org Input Devices

The X.Org configuration file (/etc/X11/xorg.conf) still has InputDevice entries for the mouse and keyboard, but they are ignored now because input-hotplug is used. The keyboard settings now come from /etc/default/console-setup; to change them please use sudo dpkg-reconfigure console-setup. After that, HAL and X need to be restarted (e.g., by rebooting your system).

X.Org evdev xmodmap incompatibility

The X keycodes generated with the new evdev input driver in X.Org 1.5 are not compatible with those generated in Ubuntu 8.04 LTS and before. If you have configured keybindings for your user with a ~/.Xmodmap file, you will need to convert or disable it by hand on upgrade.

GNOME Logout Applet

The "Logout" applet which appeared by default on the panel in earlier Ubuntu releases no longer offers the shutdown/reboot/hibernate/suspend actions. It is recommended that you remove this applet and replace it with the "User Switcher" applet, which now combines the previous "User switcher" and "Logout" applets. This change is not yet done automatically on upgrade (https://bugs.launchpad.net/bugs/274146)

UbuntuStudio real-time kernel support

No real-time kernel variant is available for the Linux 2.6.27 kernel included with Ubuntu 8.10. Users of UbuntuStudio 8.04 who need real-time kernel support are advised not to upgrade to UbuntuStudio 8.10.
