Installation

Minimum Server Software Selection Pattern Is Broken

The "Minimum Server" software selection pattern misses several packages and causes conflicts when installing additional packages. See http://bugzilla.novell.com/show_bug.cgi?id=686397 for details.

If a conflict dialog says:

pattern:minimal_base conflicts with ...

choose to "uninstall" or "not to install pattern:minimal_base". This might cause additional or different packages to be installed.

General

openSUSE Documentation

Update Applets with Changed Behavior

The default behavior of updating packages using updater applets has been changed. Now, along with system update patches from maintenance the applets also show updates respecting vendor-stickiness. This behavior affects users who are subscribed to third party repositories.

To revert back to the pre-11.4 behavior to have only system updates shown by the applets, set HidePackages=true in the [Updates] section in /etc/Packagekit/ZYpp.conf. WARNING: This way, you may miss security updates published in third party repositories.

System Upgrade

Default Download Mode Needs More Space

The Zypp download mode for package installation has been changed: It first downloads all packages, before it starts installing them. This means, it now needs more disk space. The traditional behavior was to process one package after the other.

If you are short on disk space, switch back to the traditional behavior by setting commit.downloadMode = DownloadAsNeeded in /etc/zypp/zypp.conf.

Technical

Initializing Graphics with KMS (Kernel Mode Setting)

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).

Removing the Xorg setuid bit

The setuid bit on /usr/bin/Xorg is needed for starting X as an unprivileged user, e.g., via startx. This method has been deprecated for years in favor of using a display manager. Modern environments rely on device ACLs and polkit privileges, which in turn depend upon consolekit tracking the active console, which is performed by the display manager.

Users who depend on the old configuration can set the setuid bit themselves in /etc/permissions.local by removing the comment sign from the following line:

#/usr/bin/Xorg                 root:root       4711

and running SuSEconfig --module permissions afterwards.

CIFS and NFS Services Disabled By Default

To improve boot speed the CIFS and NFS services are no longer enabled by default.

Use the YaST System Services (Runlevel) editor to enable them if needed.

Issues with syslog-ng and SQL Support

The syslog-ng package is built with SQL support enabled, packaged as a module in the syslog-ng-sql sub-package. The SQL module uses DBI, a database-independent abstraction layer in C and allows writing log data into several databases with DBI support.

At the moment, it is not recommended to use sqlite3 as the database, because a re-open of the database does not work with current DBI drivers. The issue seems to be fixed in the libdbi development version, but shipping this version would break other packages.

Intel SSD Drives Causing System Hangs

Intel SSD drives with old firmware can cause system hangs using the smartd daemon (Monitor for S.M.A.R.T. Disks and Devices), which is enabled my default.

Users should upgrade the drive's firmware. Download it from http://www.intel.com/go/ssdfirmware/.
