openSUSE in Raspberry Pi

Writing a disk image to the SD card

  1. Download the image you want (Leap is stable, Tumbleweed is rolling) from here:

    using upstream kernel (does not include hardware video decoding)
    JeOS image E20 image XFCE image LXQT image KDE image X11 image

    If the direct links above do not work for you (as we are constantly building new images), please check the general download directory for the images.

    using downstream kernel (includes hardware video decoding)

    JeOS image E20 image XFCE image LXQT image KDE image X11 image

    If the direct links above do not work for you (as we are constantly building new images), please check the general download directory for the images.

  2. As root extract the image onto your SD card (replace sdX with the device name of your SD card).
    WARNING: all previous data on the SD card will be lost. Check first if the device you have selected is really your SD card!
     xzcat [image].raw.xz | dd bs=4M of=/dev/sdX iflag=fullblock oflag=direct; sync
  3. Insert the SD card with the openSUSE image into your board.
  4. Connect the board to your PC via serial port (optional, but helpful for debugging; USB-TTL serial cable needed).
  5. Connect the board to your monitor (via DVI/HDMI, optional).
  6. Power on the board.
  7. Walk through the first boot steps.
  8. Ethernet is configured to request an IP via DHCP, check your DHCP server for the board IP if used.
  9. Have a lot of fun...
Default login is root:linux, works on serial console, via ssh, GUI.

Known Issues with Tumbleweed (upstream)

The frame buffer needs to be set to get the appropriate resolution in the x images

1. edit /boot/boot.script
  • set bcm2708_fb.fbwidth=1280 and bcm2708_fb.fbheight=1024 in bootargs
2. Then rebuild the boot.scr
  • zypper in u-boot-tools (provides mkimage)
  • mkimage -C none -A arm -T script -d boot.script boot.scr

Tips for Tumbleweed (upstream)

If you do not see any kernel output on serial or HDMI, you can add earlycon=pl011,0x20201000,115200n8 to the kernel command line for troubleshooting (e.g., by editing the GRUB menu item).

Known Issues with Tumbleweed (downstream)


Additional software for Raspberry Pi

Some additional software is available for Raspberry Pi. Some are in openSUSE repositories, others are in Packman repositories.

You should add Essentials and Multimedia repos from Packman, and also devel:ARM:Factory:Contrib:RaspberryPi, if you want to get multimedia software.

 zypper ar -f https://download.opensuse.org/repositories/devel:/ARM:/Factory:/Contrib:/RaspberryPi/standard/devel:ARM:Factory:Contrib:RaspberryPi.repo
 zypper ar -f http://pmbs.links2linux.de:82/Essentials/openSUSE_Factory_ARM/Essentials.repo
 zypper ar -f http://pmbs.links2linux.de:82/Multimedia/openSUSE_Factory_ARM/Multimedia.repo

Multimedia software

In multimedia software, you may want to install:

  • omxplayer: a command line media player making use of Raspberry Pi video hardware acceleration
  • kodi-noX-raspberry-pi: a media center (without X server and including Raspberry Pi video hardware acceleration)


Configuring the openSUSE system on the Raspberry Pi

Using the system headless

A headless system does not have a display and a keyboard connected. It is only connected to the network.

  1. The image above is setup to require a display and a keyboard to set some system parameters. However this prevents the image to start headless. The solution is to remove the file /var/lib/YaST2/reconfig_system from the ext4 partition on the SD card.
  2. Connect to the system using ssh and the login information, user: root password: linux and the IP address the system received from your DHCP server in your network.
  3. Use zypper to install the necessary services and applications (the system already contains a link to the repository containing this software).
  4. If you are not familiar using config files for services and application, but you are using YaST, you can install a number of YaST modules and use the ncurses interface to YaST to configure your system.

Manual Yast2 Install

# Note: this requires around 150MB free disk space on a freshly new SD.

# Yast2 Base:
 zypper install yast2

# Yast2 YOU base:
 zypper install yast2-online-update yast2-online-update-configuration yast2-online-update-frontend ncurses libyui-ncurses libyui-ncurses-pkg4

# Yast2 base sysconfig:
 zypper install  yast2_basis patterns-openSUSE-yast2_basis yast2-inetd yast2-network yast2-storage yast2-sysconfig yast2-trans yast2-sudo yast2-sshd yast2-runlevel yast2-pam

Yast2 .. some modules.
 zypper install yast2-instserver yast2-installation yast2-ldap-client yast2-mail yast2-samba-server yast2-samba-client 

# If you think you miss a Yast2 module, install it ...
zypper search yast2 | egrep -v '(debuginfo|debugsource|devel|Quellpaket)'
zypper install <module>

In case you want the more familiar YaST2 windows, you have to install an x11 package and a number of yast qt packages

zypper in yast2-x11 yast2-control-center-qt libui-qt-pkg4
(a number of needed packages are also pulled in) and start YaST using
In this case you have to make the ssh connection using
ssh -X root@<IP address RPi>
Warning: It may take up to 60 seconds before you get the YaST window on your screen.
  1. Have a lot of fun installing and configuring...


Warning: The openSUSE image does not have a firewall installed by default!

To install Firewall and manage it with YaST2, you need to install Yast2 and iptables:

 zypper install yast2-firewall iptables SuSEfirewall2

Resizing openSUSE RPi SD card using YaST2

To increase the size of the root filesystem itself:

It is not possible to resize a mounted filesystem, but without a mounted root you can't use any programs. So you will need a second computer to perform the following.

Warning: Potential for data loss!
  • If you have data on the SD card, make a backup & verify it!
  • Poweroff the RPi and take the SD card to a second machine.
  • Resize / Partition actions with Yast2:
 (See docu http://de.opensuse.org/YaST_Module_Partitionierer) - In German
 * The article translates nicely with Google Translate, eg the following German to English, and is easily reset to support many other languages
 * The article is very old, and supports MBR only which is likely sufficient for most cases 


  Yast2 -> menu : System -> menu : Partitioner -> Menu -> Partition: /dev/mmcblk0p3 <return> -> menu : "Resize..."
  menu : "Custom Size ", enter the size you want for the root FS, at least 2 G should be used.
  Edit the size to what you like ... i.e. 10GB
  Save & run it ("Finish").
 errors can be ignored, just force it, say yes at questions
  • Install the SD card and boot your RPi.
  • Login as root.

Run this command - may not be necessary for all builds.

  • resize2fs /dev/mmclk0p2

(see http://linux.die.net/man/8/resize2fs)

Configure Boot & System startup parameters /boot/config.txt

Warning: You may need to adjust some parameters in the file config.txt (see openSUSE:Raspberry_Pi#Custom_configuration:_config.txt) in the DOS partition to have a proper display on your screen.

Using a keyboard

Warning: As default you will get an American keyboard layout. Keep this in mind, when entering the password ...
  1. Manual way of updating keyboard:
 zypper install vim
 vi /etc/sysconfig/keyboard
  1. Change to e.g. (sample for standard german 105 keytype´s):

reboot your Pi after changes.

Configure default system runlevel for headless

with Opensuse after 12.3 for RPi systemd are the default, no sys5 init system anymore :-)

How do I change the runlevel? systemd has the concept of targets which is a more flexible replacement for runlevels in sysvinit.

Run level 3 is emulated by multi-user.target. Run level 5 is emulated by graphical.target. runlevel3.target is a symbolic link to multi-user.target and runlevel5.target is a symbolic link to graphical.target.

You can switch to ‘runlevel 3′ by running

  1. systemctl isolate multi-user.target (or) systemctl isolate runlevel3.target

You can switch to ‘runlevel 5′ by running

  1. systemctl isolate graphical.target (or) systemctl isolate runlevel5.target

To set runlevel 5 and 3 we should modify a symbolic link to point a specific Target symbolic link metric:
(runlevel 5) :

 rm /etc/systemd/system/default.target
 ln -sf /usr/lib/systemd/system/graphical.target /etc/systemd/system/default.target 
 (runlevel 3) :

 rm /etc/systemd/system/default.target
 ln -sf /usr/lib/systemd/system/multi-user.target /etc/systemd/system/default.target 

Manual Network Setup for Static IP

Steps to Setup Static Network on Factory OpenSuSE Image below
Assume your network is an Class C 192.168.1.x with Router/gateway/dns a at .1 and your local domain called "local"

echo "default - -" >/etc/sysconfig/network/routes

cp -p /etc/sysconfig/network/ifcfg-eth0_orig
cat << EOF >/etc/sysconfig/network/ifcfg-eth0
cp -p /etc/resolv.conf /etc/resolv.conf.orig
cat << EOF >/etc/resolv.conf
domain local
search local

For permanent DNS / NTP settings edit the /etc/sysconfig/network/config settings instead of /etc/resolv.conf & /etc/ntp.conf upon your own needs.

echo " MyPIHostname.local  MyPIHostname >>/etc/hosts

echo MyPIHostname >/etc/HOSTNAME

and do:

rcnetwork reload 
rcntp reload "

Disable IPV6

Steps for disabling ipv6:

echo "net.ipv6.conf.all.disable_ipv6=1" >/etc/sysctl.d/disableipv6.conf

The non-systemd way (typically for 12.2 and earlier)
Code:     sysctl -p

The systemd way (12.3 and later although the above should still work indefinitely)
Code:    systemctl restart systemd-sysctl.service

Disable LINKLOCAL / Zeroconf / on headless

The link-local ( zero conf network may not always required - i.e., at headless to disable it do the following steps:

Change "NOZEROCONF" to yes.

vi /etc/sysconfig/network/config 

save it exec : rcnetwork restart

openSUSE self kernel compile

For some RPi kernels available the source and running kernel do not match due to the automated image build failing. The workaround for this is self compile and install your own kernel.

Steps to do:

First we pick an up to date RPi kernel source from GitHub RPi - the standard kernel sources do not have all patches.

cd /usr/src
cat << EOL >git3.11.y-update.sh

cd /usr/src
if [ ! -d SOURCES ]; then
  mkdir SOURCES
if [ ! -d GIT ]; then
        mkdir GIT
cd GIT
        if [ -d .git ]; then
                rm -rf .git
                rm .gitignore .mailmap
git init


if [ -d rpi-3.11.y. ]; then
        rm -rf rpi-3.11.y

cd /usr/src/GIT
mkdir rpi-3.11.y
git fetch git://github.com/raspberrypi/linux.git rpi-3.11.y:refs/remotes/origin/rpi-3.11.y
git checkout origin/rpi-3.11.y
 mv ./* rpi-3.11.y
tar cpfj /usr/src/SOURCES/rpi-3.11.y.tar.bz2    rpi-3.11.y

cd /usr/src
tar xpfj  SOURCES/rpi-3.11.y.tar.bz2
rm linux
ln -s rpi-3.11.y linux

chmod 750 git3.11.y-update.sh nohup git3.11.y-update.sh &

This take 2-4 ...depend on your network speed and SD card , cpu load.

now we build the kernel

cat << EOL >make-linux.sh
cd /usr/src/linux
kversion=$(make -s kernelrelease)
echo $kversion

#make distclean clean
#make cloneconfig
#make oldconfig
zcat /proc/config.gz >/boot/config-$kversion
## zcat /proc/config.gz >.config
#cp -p /boot/System.map-$kversion /usr/src/linux/System.map

touch /usr/src/linux/include/linux/modversions.h
 nohup make \
 CPPFLAGS="-Ofast -mfpu=vfp -march=armv6zk -mtune=arm1176jzf-s" \
 CFLAGS="-Ofast -mfpu=vfp -march=armv6zk -mtune=arm1176jzf-s" \
 dep zImage modules &

cd linux make oldconfig cd .. nohup make-linux.sh &

This can take up to 30H ..depend on your and SD card , cpu load. This requires a swapfile configured with at least 512M - I use 1G .

once done, install it:

cd /usr/src
cat << EOL >installkernel.sh


D=`date +%Y%m%d_%H%M`
mkdir /boot.old-$D

echo "backing up /boot to  /boot.old-$D"
cp -p /boot/* /boot.old-$D/

cd /usr/src/linux
kversion=$(make -s kernelrelease)

echo "Installing selfcompiled  $kversion kernel"
cp System.map /boot/System.map-$kversion
cp System.map /boot/System.map

make ARCH=arm modules_install INSTALL_MOD_PATH=/

make ARCH=arm INSTALL_PATH=/boot/ install

cp .config /boot/config-$kversion
cp ./Module.symvers  /boot/symvers-$kversion
cp arch/arm/boot/Image /boot/kernel.img

echo "You can reboot now rebooting"
echo " In case of failures , copy back the backup from /boot.old-$D \nwith use of an sdcard reader and an Opensuse Live cd within an OS emulator Like vmware Player"
echo ""

Reboot after done that. In case of possibly failure - restore old kernel.
