If you upgrade from an older version to this openSUSE release, see previous release notes listed here: http://en.opensuse.org/openSUSE:Release_Notes
These release notes cover the following areas:
Miscellaneous: These entries are automatically included from openFATE, the Feature- and Requirements Management System (http://features.opensuse.org).
For the moment, these snippets are listed unsorted—we are working on improvements.
Installation: Read this if you want to install the system from scratch.
General: Information that everybody should read.
System Upgrade: Issues related to the process if you run a system upgrade from the previous release to this openSUSE version.
Technical: This section contains a number of technical changes and enhancements for the experienced user.
CHECKIT for 12.1!
In Start-Up, find step-by-step installation instructions, as well as introductions to the KDE and Gnome desktops and to the LibreOffice suite.
Reference covers deployment, administration, and system configuration in detail and explains how to set up various network services.
The Security Guide introduces basic concepts of system security, covering both local and network security aspects.
The System Analysis and Tuning Guide helps with problem detection, resolution and optimization.
Virtualization with KVM offers an introduction to setting up and managing virtualization with KVM, libvirt and QEMU tools.
GNOME 3 offers a new design for the desktop that is different from GNOME 2. As a result, and in order to have users benefit from the changes, the look and feel of your GNOME 2 desktop will not be migrated automatically. The System Settings can be used to customize GNOME 3, and an advanced tool (gnome-tweak-tool) is provided for more detailed customization.
The standard mode of GNOME 3 requires support for 3D acceleration in the graphic drivers. When 3D acceleration is not available, GNOME 3 then uses the fallback mode. If it turns out that GNOME 3 detects availability of 3D acceleration, but the standard mode is unusable, then you likely hit a bug in the graphic drivers. You can force the fallback mode with the "gnome.fallback=1" argument on the boot line in grub.
If you use the fallback mode, you can customize the panels by pressing Alt when right-clicking on a panel.
For a brief description of many GNOME Shell features, such as keybindings, drag and drop capabilities, and special utilities, see https://live.gnome.org/GnomeShell/CheatSheet.
The PulseAudio sound system is now system-wide integrated and enabled by default for new installation. If you disabled it on a previous release, and want to enable it now, check the PULSEAUDIO_ENABLE variable in /etc/sysconfig/sound:
Set PULSEAUDIO_ENABLE to "yes" to forcefully enable PA everywhere. Setting PULSEAUDIO_ENABLE to "no" will disable PulseAudio completely, and setting it to "custom" means to keep a custom configuration untouched.
The java-1_6_0-sun package is not anymore part of openSUSE due to a license change. We ship the OpenJDK build as a replacement. openSUSE users who prefer to use the Oracle JDK binary version over the openSUSE OpenJDK build, can download the Oracle version from http://oracle.com/java.
If encrypted partitions are not automatically mounted with systemd, the noauto flag in /etc/fstab for these partitions could be the cause. Replacing this flag with nofail will fix it. For instance, change the following line:
/dev/mapper/cr_sda3 /home ext4 acl,user_xattr,noauto 0 2
/dev/mapper/cr_sda3 /home ext4 acl,user_xattr,nofail 0 2
With openSUSE 11.3 we switched to KMS (Kernel Mode Setting) for Intel, ATI and NVIDIA graphics, which now is our default. If you encounter problems with the KMS driver support (intel, radeon, nouveau), disable KMS by adding nomodeset to the kernel boot command line. To set this permanently, add it to the kernel command line in /boot/grub/menu.lst. This option makes sure the appropriate kernel module (intel, radeon, nouveau) is loaded with modeset=0 in initrd, i.e. KMS is disabled.
In the rare cases when loading the DRM module from initrd is a general problem and unrelated to KMS, it is even possible to disable loading of the DRM module in initrd completely. For this set the NO_KMS_IN_INITRD sysconfig variable to yes via YAST, which then recreates initrd afterwards. Reboot your machine.
On Intel without KMS the Xserver falls back to the fbdev driver (the intel driver only supports KMS); alternatively, for legacy GPUs from Intel the "intellegacy" driver (xorg-x11-driver-video-intel-legacy package) is available, which still supports UMS (User Mode Setting). To use it, edit /etc/X11/xorg.conf.d/50-device.conf and change the driver entry to intellegacy.
On ATI for current GPUs it falls back to radeonhd. On NVIDIA without KMS the nv driver is used (the nouveau driver supports only KMS). Note, newer ATI and NVIDIA GPUs are falling back to fbdev, if you specify the nomodeset kernel boot parameter.
To halt and poweroff the system when using systemd, issue halt -p or shutdown -h now on the command-line or use the shutdown button provided by your desktop environment.
Note: A plain halt will not shutdown the system properly.
systemctl only supports "standard" parameters (see http://www.freedesktop.org/wiki/Software/systemd/Incompatibilities).
You can bypass this new behavior by calling the start-up script directly, for example:
cd /etc/init.d ./apache2 <your_parameters>
CUPS 1.5 comes with backward incompatible changes:
CUPS no longer supports the ~/.cupsrc or ~/.lpoptions configuration files from CUPS 1.1. Instead use ~/.cups/client.conf and ~/.cups/lpoptions that were introduced with CUPS 1.2.
The scheduler now requires that filters and backends have group write permissions disabled for improved security. If you use third party printer drivers from manufacturers with relaxed file permissions, adjust the permissions manually.
According to the GNU Coding Standards, the rename command now treats all strings beginning with a dash as a command line option. To prevent this, separate the option from the other arguments with -- as follows:
#!/bin/bash for f in *.jpg ; do rename -- ".jpg" "-$RANDOM.jpg" $f ; done
