February 27th, 2015 by

There’s a new build published today for the AMD FGLRX drivers.

It include the new patch made by Sebastian Siebert supporting Kernel 3.19x series you could have on 13.1, 13.2 and Tumbleweed openSUSE distribution.

The server just got the new rpms, so you should be able to update with zypper ref -f && zypper up

Have fun.

openSUSE miniSummit @Scale13x – summary

February 20th, 2015 by

Hi Geekos, here a small summary of our Thursday February 19th openSUSE miniSummit event here at SCale 13x.

Located in Century AB room, a 80 seats room. The average attendance rate was varying between 50% and 85%.
Qualifying the attendance 50% or more were not related to SUSE / openSUSE, which was a good experience of question and feedback.

The day started by a talk about openSUSE / SUSE Xen and openstack by Peter Linnel and Russel Pavlicek.
One hour later Manu Gupta has presented all the bolts and nuts about GSOC at openSUSE.

We then go for lunch, and corridor exchanges.

I’ve opened the afternoon with my talk “them + me = we” about breaking mythic frontier
Then just after a small break, Mark Fasheh member of filesystem SUSE Labs group has talk about the project Duperemove: dedupe on btrfs (have a look on github the source are there, and package available on obs)

The day continue with a Town Hall talk co-animated by myself and Peter running an open discussion with attendees. With interesting remarks and feedback from openSUSE users, and also complete foreigners. For example, the way systemd was introduced in openSUSE distribution was appreciated (having choice during 2 versions). It was an unstressfull, open and positive exchange.

To follow, Bryan Lunduke and Peter animated a talk about “the 10 things you would love about SUSE and openSUSE if you only you knew…”
I did really enjoy the way they numbered the slides …
Freschy, punchy, funky, the kinda talk I would like to see again at OSC15.

To finalize the day, Markus Feilner​ for Linux Magazine (de) talked about openQA.

I found interesting the perfect mix we’ve done between openSUSE and SUSE during this day, confirming the excellent partnership we have.
Let the sponsors of this day be warmly thanked to make it happened.

fonts @ openSUSE

February 17th, 2015 by

Since I maintain fontconfig, time to time I hear contradicting opinions which font families should be used in the system if not said otherwise, i. e. which families should be preferred for sans, serif and monospace generic aliases and how they should be rendered. Bug reports I got was talking about overall system defaults, concerning fontconfig rules therefore.

General idea was to weaken the word ‘default’ in regard to font setting by creating a direct window into basic fontconfig setting of the system (of course: for advanced effects, fontconfig xml coding is still needed).

For my convenience, YaST framework was used and new module called fonts had seen the light of the day not long ago. It is packaged as yast2-fonts in Tumbleweed and in my home for openSUSE 13.2.

yast-fonts-tabS

I hope that, together with fontinfo.o.o, tuning your fonts will be much easier!

Certainly, this module is not done. Firstly, I would like to fix bugs which users will meet. After this stabilizing period, perhaps next hackweek, I will consider how hard would be to add per-user setting capability to fonts-config script, which would almost automatically mean per-user font setting capability in the module itself.

SSD configuration for openSUSE

February 6th, 2015 by

As you already know, there are mechanic disks and also SSD. There is the rumor that SSDs last for 5 years or up to 5 years. Read the openSUSE wiki page for more information about openSUSE and SSD.

Here I’ll describe what I did to my SSD.

RULE 1: Partitioning

The first step is creating the right partitions. First of all, create the root partition (about 15-20GB is enough). Then create the home partition (/home). Finally leave about 7% of the disk unallocated. This will help your disk during write process. The right filesystem is ext4.

If you have new computer, then you should have a partition /boot/efi. You don’t have to do any of the following configuration for that partition.

BE CAREFUL: Don’t create a swap partition. If you already have enough memory (4GB), you don’t need it. Swap memory is “destroying” your SSD. Finally, be careful of the file system, since openSUSE 13.2 uses BTRFS as default filesystem. Snapper will create snapshots, something that you don’t need.

Linux audio library smackdown part3: SDL

February 5th, 2015 by

How many of you remember Loki Games/Entertaiment/Software? Hands up  now! I’m still waiting.. wuhuu hands up now! Loki.. Loki! Oh still no hands.. what a pity (Damn how old Am I?). Ok I Admit! It was before Steam, before Internet was this huge fast beast for watching videos, telling how you are doing right now and sharing photos.

Loki only shipped CD’s for installing your application and there wasn’t hot fixes waiting when you got CD from post or yes there where but I had to wait and wait for 200 MB blob to download for ages with my 57600 modem. All the time I thought that I’ll boot Windows for playing Castle Wolfestein. It was long before before Linux have any gaming community what so ever. There weren’t Firefox or Chrome available and Google was just starting to own our lifes.  So it was dark days of late ’90 (we had electricity thanks for asking).

Loki was founded on 1998 and  it got on bankruptcy on 2001 after IT bubble blowed. Loki changed Linux in good way. One thing that they left behind was called Simple Direct Layer (SDL1). SDL layer sits top on Xorg that makes creating games more ease. You can port your game to Windows and Mac OS X with little effort. Current version of SDL is SDL2.

Good thing about SDL is that it abstracts drawing to screen in Windows, Mac OS X and X-windows. SDL1 was all about pixel buffers but SDL2 is all about surfaces and acceleration. It support many more OSes but that’s not the what we are looking at today. So how do you playing audio out of SDL1/2?. Good thing is audio interface stayed same through conversion from SDL1 to SDL2. They only added few bugs and float point audio in SDL2.  SDL1 have recording but I didn’t manage to make it work so if anyone with more patience than me can lead me to correct path I would be happy puppy. Here is SDL Github location: https://github.com/illuusio/linux-audio-example/tree/master/sdl (more…)
