1.1 UEFI: Interface de Firmware Unificada Extensíbel

Antes de instalar openSUSE nun sistema que se inicia usando UEFI (Interface
Unificada Extensíbel do Firmware), recoméndase comprobar se hai actualizacións
do firmware que recomende o provedor de hardware e, de existiren, instalar esta
actualización. Un Windows 8 preinstalado é un grande indicador de que o seu
sistema iníciase usando 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.

1.2 Particións UEFI, GPT e MS-DOS

Xunto coa especificación EFI/UEFI chegou un novo estilo de particionamento: GPT
(GUID Partition Table). Este novo esquema usa identificadores únicos globais
(valores de 128-bit mostrados coma 32 díxitos hexadecimais) para identificar
dispositivos e tipos de particións.

Additionally, the UEFI specification also allows legacy MBR (MS-DOS)
partitions. The Linux boot loaders (ELILO or GRUB2) try to automatically
generate a GUID for those legacy partitions, and write them to the firmware.
Such a GUID can change frequently, causing a rewrite in the firmware. A rewrite
consist of two different operation: removing the old entry and creating a new
entry that replaces the first one.

Modern firmware has a garbage collector that collects deleted entries and frees
the memory reserved for old entries. A problem arises when faulty firmware does
not collect and free those entries; this may end up with a non-bootable system.

The workaround is simple: convert the legacy MBR partition to the new GPT to
avoid this problem completely.

2.1 System with LUKS-Encrypted Partition Does Not Boot

In some cases, Plymouth does not display the passphrase prompt properly. To fix
this, add plymouth.enable=0 to the kernel command line. See also https://
bugzilla.opensuse.org/show_bug.cgi?id=966255.

2.2 systemctl stop apparmor non funciona

In the past, there could be confusion over the difference between how the very
similarly named systemctl subcommands reload and restart worked for AppArmor:

  • systemctl reload apparmor properly reloaded all AppArmor profiles. (It was
    and continues to be the recommended way of reloading AppArmor profiles.)

  • systemctl restart apparmor meant that AppArmor would stop, thereby
    unloading all AppArmor profiles and then restart which left all existing
    processes unconfined. Only newly started processes would then be confined
    again.

Unfortunately, systemd does not provide a solution within its unit file format
for the issue posed by the restart scenario.

Starting with AppArmor 2.12, the command systemctl stop apparmor will not work.
As a consequence, systemctl restart apparmor will now correctly reload AppArmor
profiles.

To unload all AppArmor profiles, use the new command aa-teardown instead which
matches the previous behavior of systemctl stop apparmor.

2.3 No Default Compose Key Combination

In previous versions of openSUSE, the compose key combination allowed typing
characters that were not part of the regular keyboard layout. For example, to
produce “å”, you could press and release Shift–Right Ctrl and then press a
twice.

In openSUSE Tumbleweed, there is no longer a predefined compose key combination
because Shift–Right Ctrl does not work as expected anymore.

  • Para definir unha combinación de teclas personalizadas para todo o sistema,
    use o ficheiro /etc/X11/Xmodmap e busque as seguintes liñas:

    [...]
    !! Third example: Change right Control key to Compose key.
    !! To do Compose Character, press this key and afterwards two
    !! characters (e.g. `a' and `^' to get 342).
    !remove  Control  = Control_R
    !keysym Control_R = Multi_key
    !add     Control  = Control_R
    [...]

    To uncomment the example code, remove the ! characters at the beginning of
    lines. However, note that the setup from Xmodmap will be overwritten if you
    are using setxkbmap.

  • To define a user-specific compose key combination, use your desktop's
    keyboard configuration tool or the command-line tool setxkbmap:

    setxkbmap [...] -option compose:COMPOSE_KEY

    For the variable COMPOSE_KEY, use your preferred character, for example
    ralt, lwin, rwin, menu, rctl, or caps.

  • Alternatively, use an IBus input method that allows typing the characters
    you need without a Compose key.
