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.
If you happen to use the fallback mode, note that you can customize the panels by pressing Alt when right-clicking on them.
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 0
/dev/mapper/cr_sda3 /home ext4 acl,user_xattr 0 0
CHECKIT for 12.1. Is this entry still required?
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, there is the "intellegacy" driver (xorg-x11-driver-video-intel-legacy package) 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 only supports KMS).
