Volunteers needed!

July 29th, 2011 by
Brave enough?

Volunteers needed!

As you know, the third international openSUSE Conference is happening in a couple of weeks. You already should be registered. For the organization teams that means they are really coming onto speed now and it starts to feel dizzy.

We had a couple of public meetings which resulted in a nice list of stuff to do, like organizing hardware for the venue, set up internet, foods and drinks and so on. This is all done by community members and open for your help. If you want to help, you’re more than welcome to contribute to the conferences success. A good start is to subscribe to the mailinglist opensuse-conference@opensuse.org .

If you prefer to give a hand during the conference days, also great, we are looking for volunteers. Many hands are needed to get the event going and it would be good if we could share the work so that it’s more fun for everybody.

Please go through the list on the volunteers page and find where you could jump in and help. Simply add your name or nick into the list where you feel comfortable to help.

Thanks a lot!

New namespace for KDE apps maintained by upstream

July 19th, 2011 by

After some discussion in #opensuse-kde, darix has created the KDE:Apps namespace for KDE apps maintained by their upstream, so that they can serve fresh packages for all distributions supported by the Build Service (which includes openSUSE, SUSE Linux Enterprise, Fedora, RHEL, Debian and Ubuntu).
As the first to join in, we warmly welcome the KMyMoney project!

Got questions? Feel free to contact the openSUSE/KDE Team on the mailing list opensuse-kde@opensuse.org or in IRC: #opensuse-kde (irc.freenode.net).

LXDE and gtk3

July 19th, 2011 by

GTK3 will slowly replace the “old” gtk2, and of course, if we don’t want to be left behind we have to move to gtk3 eventually.

Even if slowly (we need horse power! –> yes we need you too!!) LXDE is being ported too. Nothing has been released yet, but a good deal of work is actually into git repositories.

X11:lxde:gtk3 project

Thanks to openSUSE Build Service (public instance of the Open Build Service) we are currently able to get git code and build it auto-magically (thanks god you created obs _services 😀 )

Right now, only five packages don’t want to build with gtk3 and they are: gpicview, libfm, lxmusic, lxpanel, pcmanfm. Everything else builds fine. As a side note, lxdm gtk greeter build but seems to crasch.

Please test those packages and report in our mailing list or even better upstream your issues.

To conclude, right now i don’t feel comfortable to push into factory gtk3 packages, so 12.1 most probably will stuck with the well know stable gtk2 packages.

Also, i’m actually working to use obs, to provide gtk3 enabled git nightly build not only to openSUSE (actually only >= 11.4) but also to Fedora 15 (already building with many successful packages) and Ubuntu/Debian. So if you are .deb packagers, please let me know, i need your help. Contact me and the lxde team using our mailing list opensue-lxde@opensuse.org

Have a great day,


Factory Progress 2011-07-18

July 18th, 2011 by

I’ve noticed the following changes that might interest people using and developing openSUSE Factory:

Package changes

GNOME 3.1.3

The GNOME team plans to have GNOME 3.2 in for openSUSE 12.1 and thus have updated to the current development release 3.1.3. They have also started removing old GNOME 2 packages that are not needed anymore.


Frederic gave an update on systemd integration. The graphical bootloader allows now to switch during boot between systemd, SysVinit and also shell code.

Also, Lennart Poettering wrote in his “systemd for developers” series about socket activation where he uses cups as example.


[gsoc] osc code cleanup – summary of week 8

July 17th, 2011 by


here’s a small summary of the 8th (coding) week. This week I spent
most of my time with rewriting the working copy code.

  • added support to add and delete packages
  • added some “abstractions” for the tracking file format:
    currently packages and files are tracked in a xml file
  • thought about the package update algorithm. Basically
    it’ll work like this (verfy simplified version):
    – perform update in a tmpdir (phase 1)
    – if the tmp update finished, copy/rename all files to
    the wc (phase 2)
    If the update is interrupted in phase 1 the wc wasn’t touched
    at all and nothing should be broken.
    If the update is interrupted in phase 2 the wc is _inconsistent_
    but a subsequent “update” call can resume the update and everything
    should be consistent afterwards (in this case only files are


  • implement update + commit algorithm

If everything works as expected most parts of working copy code
cleanup should be finished after this week.


new package squidview available

July 17th, 2011 by


squidview is one of the software, I’ve always build and installed on each squid proxy server I build for me or customers. It’s small, stable, and usefull. So it was a clear real nice candidate to be use to improve my obs and packager skiil.
I would like to thanks T1loc, yaloki, mrdocs, coolo, alin, and all others great packagers around, for helping and teaching me during the process.


Squidview is an interactive console program which monitors and displays squid logs in a nice fashion, and may then go deeper with searching and reporting functions.

(If you don’t know what squid is or does this program is probably not for you.)

To use squidview you must at least have read access to squid’s access.log file. You may need to see your administrator for this. Squidview uses this text log file for all operations. It does not generate its own database for tasks.

homepage www.rillion.net/squidview


Squidview has a number of functions. Navigate the log file with the cursor pad keys, jump to a certain day or switch to a different log file. Search for text or large http/ftp requests.

Put squidview into monitor mode: see the latest activity updated every 3 seconds (this is light on cpu load).

Reports can be generated listing the heavist Internet users and the most popular visited sites. See how many cache hits squid makes to save network traffic.

Squidview is released under the GPL.

Examples / Usage

The selected line shows a request made for a .gif at the shown time. As luck would have it, the 'H' indicates a cache hit 🙂 In this mode user traffic can scroll by.

What the above would be if viewed with less.

A tally of all users against the bandwidth they used. Kept current in near real time.

A quick investigation into the recent history of one user.

Installation / Repositories

I’ve just made a submit request against openSUSE_Factory to get it included directly, but in the meantime, you could install it from the repository server:proxy as many other useful & related packages

For example adding the repository under openSUSE_Factory

zypper ar -c -f -n "server:proxy" http://download.opensuse.org/repositories/server:/proxy/openSUSE_Factory "server:proxy"
zypper in squidview

Builds available for :

The package is build successfully against : SLES10, SLES11, openSUSE 11.3 to Factory

Have Fun!

Steampunk beautiful theme for KDM and ksplash

July 17th, 2011 by

I created packages for the nice KDM and ksplash theme Steampunk. For this theme a matching color scheme, wallpaper and mouse theme exist and those are packed in the same rpm. Youtube shows the theme in action for Kubuntu, the version in the rpm is distribution neutral. The rpm can be obtained from the home:rbos repository, I hope you enjoy the theme.

Improved Kernel Package Retention in 12.1

July 14th, 2011 by

A long awaited feature of the openSUSE update stack is finally here!
Since some time, it has been possible to tell libzypp to not delete old
kernels on update:

multiversion = provides:multiversion(kernel)

in /etc/zypp/zypp.conf. That way, you don’t have to worry that a
brand new -rc kernel from Factory makes your system unbootable. This however
solves one problem and brings another one – you have to manually delete the
old kernel so that your /boot partition does not fill up. openSUSE 12.1 will
provide a solution to this, you will be able to tell what kernels you want to
keep after an update, other kernels will be deleted. The configuration is the
same file, /etc/zypp/zypp.conf:

## Comma separated list of kernel packages to keep installed in parallel, if the
## above multiversion variable is set. Packages can be specified as
## - Exact version to keep
## latest        - Keep kernel with the highest version number
## latest-N      - Keep kernel with the Nth highest version number
## running       - Keep the running kernel
## oldest        - Keep kernel with the lowest version number (the GA kernel)
## oldest+N      - Keep kernel with the Nth lowest version number
## Default: Do not delete any kernels if multiversion = provides:multiversion(kernel) is set
multiversion.kernels = latest,running

If you configure this and the above multiversion variable, then after each
kernel update, during a subsequent reboot, a script will compare the list of
installed kernels with the multiversion.kernels setting and delete those that
are no longer needed. Examples:

  • Keep the latest kernel and the running one if it differs. This is similar to
    no enabling the multiversion feature at all, except that the old kernel is
    removed after reboot and not immediatelly after installation. BTW, you
    probably always want to include “running”:

    multiversion.kernels = latest,running
  • Keep last two kernels and the running one:
    multiversion.kernels = latest,latest-1,running
  • Keep the latest kernel, the running and a my test kernel with a fancy

    multiversion.kernels = latest,running,3.0.rc7-test

If you want to try it, it’s all in Factory already. Check if these packages are
recent enough and uncomment the two variables in zypp.conf:

$ rpm -q --changelog kernel-desktop mkinitrd libzypp | grep -B2 312018
* Fri Jun 17 2011 mmarek@suse.cz
- rpm/post.sh: Touch /boot/do_purge_kernels on package install
- Add purge-kernels script to automatically delete old kernel packages
  on boot, based on configuration in /etc/zypp/zypp.conf, variable
  multiversion_kernels (fate#312018).
* Tue Jun 21 2011 dmacvicar@suse.de
- Add configuration template for automatic kernel
  purge (feature#312018) to zypp.conf
$ grep ^multiversion /etc/zypp/zypp.conf
multiversion = provides:multiversion(kernel)
multiversion.kernels = latest,running

Happy updating!

Zippl again – now in the package

July 12th, 2011 by

lightweight presentations

some might remember my hackweek project Zippl. I blogged about it more than a year ago. Zippl is a lightweigt presentation tool, a bit like prezi, a hipp tool for that purpose, where all ‘slides’ sit on one large canvas and during the presentation a kind of camera moves over the canvas.

I liked the idea and did Zippl as I wanted to play with Qt’s QGraphicsView. It takes a simple xml file as input which describes the presentation and animates it as shown in the video in my older blog.

First I thought it doesn’t make sense to continue that project. But recently, somebody asked if I have built in the feature back to the previous spot as I promised almost a year ago, as he wanted to do a presentation with Zippl. I couldn’t believe, and so I spent an evening in the weekend to polish Zippl a bit. And because its easy with OBS, I quickly built an rpm package for various openSUSEs.

Now that I worked on it a bit again I found it could also make sense on tablet devices, for example to run cool Hello New User animations or small presentations for ant Tilly to get some sponsorship for the new bike. Could be fun.

If you want to check it, please install from my home repository.

Presentation resolution on netbooks

July 11th, 2011 by

I recently got ASUS Eee Netbook R051PX, nice little machine, however small annoyance it has when plugged to projectors for presentation is that the default mirrored resolution is just 800×600, the gnome-display-properties does not allow the selection of 1024×768, xrandr comes to the rescue:

Run the following as normal user in terminal to get the required resolution.

xrandr --output LVDS1 --panning 1024x768
xrandr --output VGA1 --mode 1024x768

Note: just in case wordpress eats up – character, there are 2 – before output, panning and mode.
