3.2. UEFI—Unified Extensible Firmware Interface

Prior to installing openSUSE on a system that boots using UEFI (Unified
Extensible Firmware Interface) you are urgently advised to check for any
firmware updates the hardware vendor recommends and, if availale, to
install such an update. A pre-installed Windows 8 is a strong indication
that your system boots using UEFI.

Background: Some UEFI firmware has bugs that cause it to break if too much
data gets written to the UEFI storage area. Nobody really knows how much
"too much" is, though. openSUSE minimizes the risk by not writing more than
the bare minimum required to boot the OS. The minimum means telling the
UEFI firmware about the location of the openSUSE boot loader. Upstream
Linux Kernel features that use the UEFI storage area for storing boot and
crash information (pstore) have been disabled by default. Nevertheless it
is recommended to install any firmware updates the hardware vendor
recommends.

4. Actualizare sistem

4.1. systemd: Activating NetworkManager with a network.service Alias Link

By default, you use the YaST Network Settings dialog (yast2 network) to
activate NetworkManager. If you want to activate NetworkManager, proceed as
follows.

The NETWORKMANAGER sysconfig variable in /etc/sysconfig/network/config to
activate NetworkManager has been replaced with a systemd network.service
alias link, which will be created with the

systemctl enable  NetworkManager.service

command. It causes the creation of a network.service alias link pointing to
the NetworkManager.service, and thus deactivates the /etc/init.d/network
script. The command

systemctl -p Id show network.service

allows to query the currently selected network service.

To enable NetworkManager, use:

  • First, stop the running service:

    systemctl     is-active network.service && \
     systemctl     stop      network.service

  • Enable the NetworkManager service:

    systemctl --force        enable NetworkManager.service

  • Start the NetworkManager service (via alias link):

    systemctl     start     network.service

To disable NetworkManager, use:

  • Stop the running service:

    systemctl     is-active network.service && \
     systemctl     stop      network.service

  • Disable the NetworkManager service:

    systemctl disable NetworkManager.service

  • Start the /etc/init.d/network service:

    systemctl     start  network.service

To query the currently selected service, use:

systemctl -p Id show     network.service

It returns "Id=NetworkManager.service" if the NetworkManager service is
enabled, otherwise "Id=network.service" and /etc/init.d/network is acting
as the network service.

4.2. SYSLOG_DAEMON Variable Removed

The SYSLOG_DAEMON variable has been removed. Previously, it was used to
select the syslog daemon. Starting with openSUSE 12.3, only one syslog
implementation can be installed at a time on a system and will be selected
automatically for usage.

For details, see the syslog(8) manpage.

5. Detalii tehnice

5.1. Inițializarea graficii cu 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 using
Grub 2, the default boot loader, add it to the GRUB_CMDLINE_LINUX_DEFAULT
kernel default load options line in your /etc/default/grub text file as
root and running the terminal command

sudo /usr/sbin/grub2-mkconfig --output=/boot/grub2/grub.cfg

for the changes to take effect. Else, for Grub Legacy, add it to the kernel
command line in /boot/grub/menu.lst, also done as root. 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.

5.2. systemd: Se curăță directoarele (/tmp și /var/tmp)

By default, systemd cleans tmp directories daily as configured in /usr/lib/
tmpfiles.d/tmp.conf. Users can change it by copying /usr/lib/tmpfiles.d/
tmp.conf to /etc/tmpfiles.d/tmp.conf and modifying the copied file. It will
override /usr/lib/tmpfiles.d/tmp.conf.

Note: systemd does not honor obsolete sysconfig variables in /etc/sysconfig
/cron such as TMP_DIRS_TO_CLEAR.

5.3. Configuring Postfix

The SuSEconfig.postfix was renamed as /usr/sbin/config.postfix. If you set
sysconfig variables in /etc/sysconfig/postfix or /etc/sysconfig/mail, you
must manually run /usr/sbin/config.postfix as root.

5.4. GNOME: Workaround to Set Shift or Ctrl+Shift as Shortcut Keys for
Input Source Selection

In Gnome 3.6 use the following workaround to set Shift or Ctrl+Shift as
shortcut keys for input source selection:

 1. Install gnome-tweak-tools.

 2. Then in the 'Typing' section, at the very bottom, find the
    'Modifiers-only input source switch' option, where you can set Ctrl
    Shift_L, for example (meaning, Ctrl key and left shift) or Shift_L
    Shift_R (meaning both Shift Keys).

This is also being tracked in the upstream bug report https://
bugzilla.gnome.org/show_bug.cgi?id=689839.
