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 SUSE KDM theme does not allow Windows Domain logons.
To work around this issue, set DISPLAYMANAGER_KDM_THEME to an empty string in
/etc/sysconfig/displaymanager to use the default KDM theme:
DISPLAYMANAGER_KDM_THEME=""
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.
Technical
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.
Due to problems on some hardware HDMI sound output has been disabled by default on the radeon driver, which is the default driver for AMD/ATI graphics cards.
It can be re-enabled by adding
radeon.audio=1 as a kernel parameter. In YaST, go to System -> Boot Loader, then click Edit on the default entry, and add the following to the end of 'Optional Kernel Command Line Parameter':
radeon.audio=1
Then reboot to apply the change.
Alternatively, users can install the proprietary driver from AMD. For more information, see
http://en.opensuse.org/SDB:ATI_drivers.
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.
By default, openSUSE now boots using
systemd. In case of trouble, you can switch back to the old way using
sysvinit by pressing the F5 key on the boot.
If you want to switch to
sysvinit permanently, install the
sysvinit-init package. To switch back to
systemd, reinstall the
systemd-sysvinit package.
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
Unprivileged users can no longer write to
/usr/src/packages.
rpmbuild> now uses
~/rpmbuild by default. To change the directory add a line as follows to
~/.rpmmacros:
%_topdir /some/where/else
To use the subdirectory
foo of
$HOME add to
~/.rpmmacros:
%_topdir %{getenv:HOME}/foo

System Upgrade
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
to
/dev/mapper/cr_sda3 /home ext4 acl,user_xattr,nofail 0 2
